If the simple interest on $7,000 for 9 years is 3,780, then what is the interest rate?

Answer:

50

Step-by-step explanation:

a + 30 + 20=100

100-30=70

70-20=50

Answer: 50 marbles

Step-by-step explanation: 100-(30+20)=50

Answer:

Step-by-step explanation:

given: x-y = 4

x=4+y

given: -10x + y = -58

plug in for x

-10(4 + y) + y = -58

-40 - 10y + y = -58

-9y = -18

y = -18 / -9

y = 2

now plug in 2 for y in the first equation

x-2=4

x=6

There is the solution  x=6, y=2  :)

Answer:

6

Step-by-step explanation:

3 / 1 - 1/2 = 3 / 1/2

when dividing by singular fractions (1/3 1/6 1/29 whatever) just multiply by the denominator so 3 ÷ 1/2 = 6

Answer:

The diagonals bisect each other

Step-by-step explanation:

2s = 10    s+5 = 10      FJ = JH

t+12 = 18   3t = 18    EJ = JG

Answer:

28.4 miles/gallon

Step-by-step explanation:

to find the answer, you need to find the constant by dividing the miles drove by the amount of gasoline (or the other way around in terms of wording if it is not correct grammar) So you need to do 35.5/1.25 .  FYI I converted the fraction to decimal. The answer is 28.4 miles/gallon.

Hope this helped!! :)

Answer:

2.20E17 is 220,000,000,000,000,000 kg

Answer:

The value of the expression when x = -1 and y = 2 is -16.

Step-by-step explanation:

Firstly, let's look at [tex]x^{3}[/tex].

As the question provides, the value of x is -1. Therefore, we have to find the value of [tex](-1)^{3}[/tex], which is -1.

Now, moving onto [tex]y^{2}[/tex].

The question provides us with y = 2. Simply substitute this value into [tex]y^{2}[/tex], and we get [tex]2^{2} = 4[/tex].

Finally, concluding the equation, we get 4(-1)(4). That is equal to -16, which is our answer.

Hope this helped!

Answer:

∠1 and ∠5 are pair of corresponding angles

∠1 and ∠8 are pair of alternate exterior angles

∠3 and ∠6 are pair of alternate interior angles.

Step-by-step explanation:

we need to identify the pair of corresponding angles, a pair of alternate exterior angles and a pair of alternate interior angles.

1) Pair of corresponding angles

Angles that are at the same corner at each intersection.

So, ∠1 and ∠5 are pair of corresponding angles

2) Pair of alternate exterior angles

A pair of angles that are on outer side of the two lines but on opposite sides of the transversal.

So, ∠1 and ∠8 are pair of alternate exterior angles

3) Pair of alternate interior angles

A pair of angles that are on inner side of the two lines but on opposite sides of the transversal.

So, ∠3 and ∠6 are pair of alternate interior angles.

35/ 7

3x+1 = 5

3x= 4

x= 4/3

Answer: x=4/3

Step-by-step explanation:

1. Distribute

7(3x+1)=35

21x+7=35

2. Subtract 7 from both sides of the equation

21x+7=35

21x+7-7=35-7

3. Simplify

Subtract the numbers

Subtract the numbers

21x=28

4. Divide both sides of the equation by the same term

21x=28

21x/21 28/21

5. Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=4/3

Answer:

137°

Step-by-step explanation:

Basically, its the reverse of question 1.

With angle x, you can find out that the opposite angle is 360 - 106 = 254°

the angle is twice the size of angle y as said in the corcle theorems.

254 divided by 2 = 137°

Answer:

11

12

does not

Step-by-step explanation:

If we know how much money the coach has and how much each bag costs we can find out how much bags the coach can by by divide the money the coach has by the price of one bat bag. So we do....

605 / 55 = 11

So now we know that she can by 11 bags maximum, while she needs 12 bags for the team. From this we know that she does not have enough money to buy 12 bags.

Answer:

Basically, it is asking what fraction equals 15 / 1 ?

And the answer is 60 miles / 4 gallons

Step-by-step explanation:

(22.11 - 4.29) /3 = X

22.11- 4.29 = 17.82

17.28/3 = 5.94

One bag of apples cost $5.94

Answer:

(22.11-4.29)÷3=x

(17.82)÷3=5.94

x=$5.94

Answer:

3rd option. The way you do it is just plug in negative x value let's say -8, plug it in then y would be a positive value. So that rules out first two options. Then plug in positive x value, y would be negative.

Step-by-step explanation:

Step 1: Define Equation

4x - 8 = 16

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 16 does indeed equal 16.

∴ x = 6 is the solution to the equation.

Step-by-step explanation:

Answer:

5 of the 7 boxes are 8 inches in height

Step-by-step explanation:

Mathematically;

1 ft = 12 inches

So, 5 ft will measure 5 * 12 = 60 inches

So from what we have ,

We want to combine 8 and 10 inches to give 60 inches total

Let the number of 10 inches be x and the number of 8 inches be y

Mathematically;

x + y = 7 •••••(i)

10x + 8y = 60 ••••(ii)

From equation i, x = 7-y

Put this in equation ii

10(7-y) + 8y = 60

70-10y + 8y = 60

70-60 = 10y-8y

2y = 10

y = 10/2

y = 5

Answer:

5x<45 Divide both by five which results in the equation looking like this:x<9. On a number line, there would be an open circle on the nine and the arrow would go to the left.

Step-by-step explanation:

The solution set is x<9 of inequality 5x<45.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

5x<45

divide by 5

x<9

The graph is the shaded region below x =9.

Therefore, the solution set is x<9. And the graph is given.
