Answer:
w = 24
Step-by-step explanation:
= 15
Multiply both sides by 8.
5w = 15 × 8
= 120
Find w.
w = 120 ÷ 5
w = 24
23=79(6x−36)+9
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.

d. nonagon
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
Answer:
9 pies
Step-by-step explanation:
72 pieces divided by 6 slices = 12-3=9
Answer:
Step-by-step explanation:
72 pieces divided by 6 pieces in each pie=12 pies
The cafeteria gave 3 pies so the club made 9. 12-3=9
