Eight more than four times a certain number is

Mathematics
1 answer:
yKpoI14uk [10]3 years ago
4 0

Answer:

<h2>The answer is 5.</h2>

Step-by-step explanation:

Let the number be x

Eight more than four times a certain number is written as

8 + 4x

12 less than eight times the number is written as

8x - 12

Equate them

We have

8 + 4x = 8x - 12

8x - 4x = 8 + 12

4x = 20

Divide both sides by 4

<h3>x = 5</h3>

Hope this helps you

which equation, written in standard form correctly represents this scenario and indicates what the variables represent?
pishuonlain [190]

The answer is the third option.

The explanation is shown below:

1. You must keep on mind the information given in the exercise:

- She bough 3 pounds of coffee.

- She bought 2 pounds of chocolate.

- She spent a total of $24.

2. Therefore, you can call the price per pound of coffee x and the price per pound of chocolate y.

3. When you multiply 3 pounds by the price per pound of coffee, you obtain the amount of money she spent for 3 pounds. When you multiply 2 pounds by the price per pound of chocolate, you obtain the amount of money she spent for 2 pounds. If you add both amounts, you obtain the total spent, which was $24.

4. Therefore, you can express this as following:

3x+2y=24

What is the missing length?
skad [1K]

Answer:

6.1

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) * h  where b1 and b2 are the lengths of the bases

108.6 = 1/2 ( 12+p) *12

108.6 = 6 (12+p)

Divide each side by 6

108.6 /6 = 12+p

18.1 = 12+p

Subtract 12 from each side

18.1-12 = 12+p-12

6.1 = p
