−15x−40=23−8x
What does x =
2 answers:
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
<em>add 8x to both sides to bring -8x to the left side</em>
-15x + 8x - 40 = 23
<em>add 40 to both sides to bring -40 to the right side</em>
-15x + 8x = 23 + 40
<em>add the common terms</em>
-7x = 63
<em>for x to be alone divide -7 to both sides</em>
x = -9

Answer:
√75, 9, 9.5, √99, 10
Step-by-step explanation:
that's what I got
Step 1. Simplify 10/3b to 10b/3
12/5(10b/3 + 15/4)
Step 2. Distribute
8b + 9
Answer:
Step-by-step explanation:
base length b = 32 cm
slant height L = 30 cm
height h = √(L²-(½b)²)
= √(30²-0.25·32²)
≅ 25.3771550809 cm
volume V = (⅓)b²h
= (⅓)32²·25.38
≅ 8662.07 cm³
