Answer:

You can't solve this unless you have the amount of the other alloy.

Step-by-step explanation:

For example, the question should be something like:

A jeweler is using 10 pounds of alloy that is 2% platinum. He has another alloy that is 5% platinum. He wishes to combine these mixtures to form a mixture that is 3% platinum. How many pounds of the second alloy should be added to the first to get a mixture that is 3% platinum?

Answer:

79

Step-by-step explanation:

From Question, we are told that, there are 14 rows of seat with is divided into left hand side and right hand side

Seats by the right = fit two people

Seats by the left = fit three people

This means, 1 row of seat can contain 5 persons

The back seat = 8 people can sit comfortably.

Hence, the number of people that can ride the bus at one time =

(14 × 5 people) + 8 people (backseat) + 1 driver

= 70 + 8 + 1

= 79 people

Step-by-step explanation:

Equation at the end of step 1

(3x2 - 38x) + 24 = 0

STEP2:Trying to factor by splitting the middle term

 2.1     Factoring  3x2-38x+24 

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -38x  its coefficient is  -38 .

The last term, "the constant", is  +24 

Step-1 : Multiply the coefficient of the first term by the constant   3 • 24 = 72 

Step-2 : Find two factors of  72  whose sum equals the coefficient of the middle term, which is   -38 .

     -72   +   -1   =   -73     -36   +   -2   =   -38   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -36  and  -2 

                     3x2 - 36x - 2x - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                    3x • (x-12)

              Add up the last 2 terms, pulling out common factors :

                    2 • (x-12)

Step-5 : Add up the four terms of step 4 :

                    (3x-2)  •  (x-12)

             Which is the desired factorization

Equation at the end of step2:

(x - 12) • (3x - 2) = 0

STEP3:Theory - Roots of a product

 3.1    A product of several terms equals zero. 

 When a product of two or more terms equals zero, then at least one of the terms must be zero. 

 We shall now solve each term = 0 separately 

 In other words, we are going to solve as many equations as there are terms in the product 

 Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

 3.2      Solve  :    x-12 = 0 

 Add  12  to both sides of the equation : 

                      x = 12

Solving a Single Variable Equation:

Step-by-step explanation:

[tex]if \: (x + 12) = (3x + 2) \\ 12 - 2 = 3x - x \\ 2x = 10 \\ x = 5 \\ \\ \\ if(x + 12)(3x + 2) = 0 \\ x + 12 = 0 \: \: \: or \: \: \: 3x + 2 = 0 \\ x = - 12 \: \: \: or \: \: \: x = - \frac{2}{3} [/tex]

Answer:

60 cm

Step-by-step explanation:

remember, the area of a triangle is found by

1/2 b h

or half of the base times the height

so using that plug in the values:

the base is made of two 5s;  2* 5 is 10 so the base is 10cm long

the height is 12cm

so

1/2 * 12 * 10

= 6 * 10

= 60

Answer:

I think its 60

Step-by-step explanation:

To find the area of a triangle you do (height x base) divided by 2

5+5=10

12 x 10 = 120

120 divided by 2 is 60

Answer:

[tex]\dfrac{x}{4} \le 35[/tex]

Step-by-step explanation:

There are 4 people splitting the gas cost equally.

Each person will pay at most $35, so the gas cost to each person can be less than $35 or equal to $35.

The total gas cost is x. The gas cost for each person is 1/4 of the total, so it is x/4.

Answer:

[tex]\dfrac{x}{4} \le 35[/tex]

see what should to do buddy :

step 1-

first we have to find the gradient of the line like this:

a ( 1 , 1 )

b ( 3 , 4 )

.

step 2-

now just need one of the a or b point to put in this equation :

.

step 3-

to find the standard form of the line we have to take the y alone.

so we add the sides of the equation plus 1.

[tex]y = \frac{3}{2}x - \frac{3}{2} + 1 \\ \\ \\ y = \frac{3}{2}x - \frac{1}{2} [/tex]

And we're done.

good luck buddy ♥️♥️♥️♥️♥️

Standard form of the line passing through points (1, 1) and (3, 4) is

y = (3 / 2)x  - (1 / 2).

"Line is a one dimensional figure which has only one dimension that is length no other dimension present in it."

Formula used

( x₁ , y₁) and (x₂ , y₂) are the two points through which line passes

[tex]\frac{x-x_{1} }{x_{2} -x_{1} } =\frac{y-y_{1} }{y_{2} -y_{1} }[/tex]

According to the question,

Given ,Line passes through points( 1, 1 )and (3,4)

Substitute the value in the formula to get standard form of line we get,

  [tex]\frac{x-1 }{3 -1} =\frac{y-1 }{4 -1 }[/tex]

⇒3(x -1) = 2(y -1 )

⇒3x -3 = 2y -2

⇒y = (3/2)x - (1/2)

Hence, standard form of the line passing through points (1, 1) and (3, 4) is

y = (3 / 2)x  - (1 / 2).

Answer:

A or x = 1

Step-by-step explanation:

So we can see from the most right column that the sum of the three number is  9 (2 + 4 + 3) so we know that every row or column has to add up to 9. We want to find x so we must make sure that, 8 + 0 + x should be 9 and 2 + 6 + x should be 9. From 8 + 0 + x, we know that 8 + 1 is 9 so x is 1. We can also see that 2 + 6 is 8 and 8 + 1 is 9 so x = 1.

Answer:

4.25$ per pair of skates

Step-by-step explanation:

Subtract 9.25 from 39. You get 29.75. Just divide 29.75 by 7 and you get 4.25

Answer:

let the first no. be x

then the second no. = x - 6

their sum is 48

therefore,

[tex] = > x + (x - 6) = 48 \\ = > 2x = 48 + 6 \\ = > 2x = 54 \\ = > x = \frac{54}{2} \\ = > x = 27[/tex]

The value of first no. = x = 27

The value of second no. = x - 6 = 27 - 6

Answer: D

Step-by-step explanation:

First, remember two things about translations.

For a function f(x).

A horizontal translation to the right of N units is written as:

f(x - N)

A vertical translation up of N units is written as:

f(x) + N.

Now let's look at the graph.

You can see that:

g(x) is: 4 units at the right of f(x) and 3 units bellow f(x).

Then we have:

g(x) = f(x - 4) - 3.

and f(x) = ∛x

then g(x) = ∛(x - 4) - 3

The correct option is D.

The function g(x) is transformed from the function f(x) by translating function f(x) by 4 units in the right direction and then by translating that graph 3 units in a downward direction.

Given :

Function --   [tex]\rm f(x) = \sqrt[3]{x}[/tex]

The following steps can be used to determine the unknown function g(x):

Step 1 - According to the given graph, translate function f(x) 4 units in the positive x-axis that is in the right direction.

Step 2 - Now, again according to the given graph, translate function f(x) 3 units in the downward direction that is in the negative y-axis.

Step 3 - The resulting graph is the graph of the function g(x). Whose equation is written as:

[tex]\rm g(x) = \sqrt[3]{x-4} - 3[/tex]

So, the correct option is D).

Answer:

The number of rabbits Katniss caught = 10 rabbits

Step-by-step explanation:

The number of squirrels Katniss caught = 3 × (The number of deer she caught)

The number of rabbits Katniss caught = The number of squirrels she caught - 5

The total number of animals she caught = 10 + 4 × (The number of deer she caught)

Let the number of deer Katniss caught = D

∴ The number of squirrels she caught = 3×D

The number of rabbits Katniss caught =  3×D - 5

The total number of animals she caught = 10 + 4 × D

Therefore, we have;

The number of squirrels she caught + The number of deer she caught + The number of rabbits she caught = 10 + 4 × D

3×D + D + 3×D-5 = 10 + 4 × D

7·D - 5 = 10 + 4·D

7·D - 4·D = 10 + 5

3·D = 15

D = 15/5 = 5

∴ The number of deer Katniss caught = D = 5

The number of rabbits Katniss caught =  3×5 - 5 = 10

The number of rabbits Katniss caught = 10 rabbits.

Answer:

x= -4 y= -1

Step-by-step explanation:

6x - y = - 23

-y=-23-6x

y=6x+23, use this to plug in for y in the second equation.

2x + 5y = -13

2x + 5(6x+23) = -13

2x+30x+115=-13

x= -4, use this to plug in for x in the first equation.

6x - y = - 23

6(-4)-y=-23

-24-y=-23

-y=-23+24

-y=1

y= -1

The values after solving the equations by substitution is that the value of x is -4 and the value of y is -1.

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the provided data in the question,

6x - y = -23  (i)

2x + 5y = -13  (ii)

Multiply equation (ii) by 3

6x + 15y = -39 (iii)

Solve equation (i) and (iii)

-16y = 16

y = -1

Substitute y = -1 in equation (i)

6x = -23 - 1

x = -4.
