Answer 1

Answer:

Answer:

w = 24

Step-by-step explanation:

$(5w)/(8)$ = 15

Multiply both sides by 8.

5w = 15 × 8

= 120

Find w.

w = 120 ÷ 5

w = 24

Rebecca sold 11 more magazine subscriptions than Chad.Laura sold 4 more than Rebecca.Laura sold 45 magazine subscriptions.How many magazine subscriptions did Chad sell?

Answers

Since Laura sold 4 more than Rebecca, you subtract 4 from 45 which is 41, and Rebecca sold 11 more than Chad, you subtract 11 from 41 which is 30.
Laura sold 45 magazine.
Rebecca sold 41 magazine.
Chad sold 30 magzine.

$45-4 = 41 \ (Rebecca) \n\ 41-11 = 30 \ (Chad)$

Solve for x.

23=79(6x−36)+9

Answers

23=474x-2844+9
23=474x-2835
-474x=-2835-23
-474x=-2858
x=1429/237

23 = 79(6x - 36) + 9

Distribute 79 inside the parentheses.

23 = 474x - 2,844 + 9

Combine like terms.

23 = 474x - 2,835

Add 2,835 to both sides.

2,858 = 474x

Divide both sides by 474.

x = 2,858/474

Simplified by dividing both sides by 2: 1,429/237

Your answer is x = 1,429/237.

Molly's jump rope is 6 1/3 feet long. Gail's jump rope is 4 2/3 feet long. How much longer is Molly's jump rope?

Answers

If you would like to know how much longer is Molly's jump rope, you can calculate this using the following steps:

6 1/3 feet long - 4 2/3 feet long = 6 1/3 - 4 2/3 = 19/3 - 14/3 = 5/3 = 1 2/3

The correct result would be 1 2/3 feet longer.

Molly's jump rope is: 6 1/3 feet long
Gail's jump rope is: 4 2/3 feet long

The Question asks how much longer is Molly's jump rope than Gail's

Lets write it as an algebraic expression:

4 2/3 + x = 6 1/3

Next we should subtract 4 2/3 from both sides of the equation:

4 2/3 - 4 2/3 + x = 6 1/3 - 4 2/3
x = 2 -1/3

x is equal to two negative one third feet

Question olve the following quadratic by factoring. a^(2)-4a-12=0

Answers

Answer:

a = - 2 , a = 6

Step-by-step explanation:

a² - 4a - 12 = 0

consider the factors of the constant term (- 12) which sum to give the coefficient of the a- term (- 4)

the factors are + 2 and - 6, since

+ 2 × - 6 = - 12 and + 2 - 6 = - 4

use these factors to split the a- term

a² + 2a - 6a - 12 = 0 ( factor the first/second and third/fourth terms )

a(a + 2) - 6(a + 2) = 0 ← factor out common factor (a + 2) from each term

(a + 2)(a - 6) = 0 ← in factored form

equate each factor to zero and solve for a

a + 2 = 0 ( subtract 2 from each side )

a = - 2

a - 6 = 0 ( add 6 to both sides )

a = 6

solutions are a = - 2 , a = 6
