Answer= 170.121

Step-by-step explanation:

You will first take 123.456+45.678+0.987=170.121

hope it will help:)

From the information in the word problem we are able to set up the following inequality:  

3y + 2 - y = 12   |   where x is the larger number of two numbers in a set (x, y)  

We know this because the problem states that [x = 3y + 2] or 3 times the smaller number plus two.  

We also know that x - y = 12.

So, we substitute x in [x - y = 12] with 3y + 2 that we found out above, and we get the following:

3y + 2 - y = 12

Now, we solve the inequality

3y + 2 - y = 12

-> subtract 2 from both sides :: 3y - y = 10

-> subtract y from 3y              :: 2y = 10

-> divide both sides by 2        :: y = 5

So now we have y, the smaller number, which is equal to 5. Next, to find x we simply plug y=5 back in to either the value of x, [3y + 2], or the inequality of x - y = 12. I will show both:  

x - y = 12

-> substitute y for 5     :: x - 5 = 12

-> add 5 to both sides :: x = 17

OR

3y + 2 = x

-> substitute y with 5 :: 3(5) + 2 = x

-> multiply 3, 5          :: 15 + 2 = x

-> add 15, 2              :: 17 = x

So there you have it:  

x = 17 , y = 5

You can go back and use these values to check your answer and make sure they work with the word problem.  

Remember to look for the setup to an inequality in the word problem. Anything that says BLANK times this number, or 4 less than that number, is trying to set you up with an inequality problem.

Answer:

120 Jumps per Minute

Step-by-step explanation:

3 Seconds per jump

So we do 60 (seconds in a minute) / 3 (seconds)

We get 20, this is how many times we do the 6 jumps.

Then we simply do 6x20 to get 120 jumps per minute!

Answer:

Drinks = $1.5

Pizza = $10.50

Step-by-step explanation:

let d = drinks

p = pizza

p = 7d  equation 1

2p + 8d = 33 equation 2

from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2

2p = 7d x 2 = 14d  eqn 3

Substitute for 2p in equation 2  

14d + 8d = 33

22d = 33

Divide both sides of the equation by 22

d = $1.5

Substitute for d in equation 1

p = 1.5 x 7 = $10.5

Answer:

2835

Step-by-step explanation:

-9×5= -45

-9×7= -63

-45×(-63)=2835

Answer: x - 1.5

4x – 97 + 12 – x = -80.5

3 x - 85 = -80.5

3 x - 85 +85 = -80.5 + 85

3x = -80.5 + 85

3x = 4.5

x = 1.5

Step-by-step explanation: hope this helps

Answer:

x=1.5

Step-by-step explanation:

4x-97+12-x=-80.5

Combine like terms

-97+12=-85

4x-x=3x

now you have 3x-85=-80.5

add 85 to both sides and now you have

3x=4.5

Now divide 3 to both sides and you get x=1.5

Answer:

$5.53 i think

Answer:

SSS.

Step-by-step explanation:

The 3 sides are congruent . The  ones that are marked and the middle line which is common to both triangles.

Answer:

One solution

Step-by-step explanation:

3-2x=5-x+3+4x

3-2x=3x+8       Combine like terms

3-8-2x+2x=3x+2x+8-8         Minus or add terms to get x on one side by itself

-5=5x        Divide 5 to both sides to get x by itself

5    5      

x=-1           The 5 is cancelled out on the side with the x and then divide it on                       the side with -5

Answer:

area = l * w

= (3x + 1) * (2x + 3)

Answer:

50 + 4 + .9 + .06

Step-by-step explanation:

Answer:

x+9

Step-by-step explanation:

f(x) = x, going up 9

that is y=x, going up 9

if you wnat to go up, subtract 9 from y

y -9 = x

y=x+9

convert back to f(x)

f(x) = x+9

Answer:

y=1

Step-by-step explanation:

it is in the middle of the maximum and minimum.

If one is positive we can conclude that the other is also positive

Positive*positive=positive(24)

The product of the two numbers is 24

And the smaller number is less than the greater number by 2

Factors of 24=1*24,2*12,3*8,4*6.

The only pair with the diffrence of two is 4*6

Therefore the two integers are 4 and 6

Answer: The correct answer is 250 miles per day. I just completed this question myself and I got it correct

Step-by-step explanation:

Answer:

102,9 cm^2

Step-by-step explanation:

First of all we can find the area of the two rectangles at the sides of the figure

A rectangle = length x width = 8 x 4 = 32 cm^2

the rectangles are two so:

32 x 2 = 64 cm^2

for the figure in the center we can proceed like this: we can initially assume that also it is a rectangle, so we have to find the length

length = 16-8 = 8 cm

A = 8^2 = 64 cm^2 (so we have discovered that is a square)

if we look we can see that there is also a semicircle that is not part of the figure. We have to find its area and subtract it to the area of the square

A semiciricle = (radius^2 π)/2

radius = 8/2 = 4 cm

A semicirlce = (4^2) π/2 = 25,13 cm^2

64 - 25,13 = 38,87 cm^2

At least we have to added up this value to the area of the two rectangles

total area = 38,87 + 64 = 102,87 = 102,9 cm^2

Answer:

There will be total 855 flowers.

Step-by-step explanation:

Suppose there are 9 total rows and each row has total 19 plant and each plant has 5 flowers.

Then the number of  flowers can be found out by simply multiplying

9*19*5= 855

There will be total 855 flowers (if the above given numbers assumed are the same as the original question)

IF the numbers are changed from the above assumed numbers even then the answer can be obtained by simply multiplying the numbers to get the total numbers of flowers.
