Answer:
see below
Step-by-step explanation:
8+3m= -7
Subtract 8 from each side
3m+8-8= -7-8
Combine like terms
3m= -15
Divide each side by 3
3m/3 = -15/3
m = -5
Check
8+3m= -7
8+3(-5) = -7
8-15 = -7
-7 = -7
m = -5 is the solution

your answer is (A.)
Step-by-step explanation:
Answer:
V candle ≈ 196.9 cm³
Step-by-step explanation:
Volume of cone = ( π·r²·h)/3
V candle = V big cone -V small cone
V candle = [ π·4²·(8+5) - π·2²·5]/3
V candle = ( π·16·13 - π·4·5)/3
V candle = (π·16·13 - π·4·5)/3
V candle = π·(208 - 20)/3
V candle = π·188/3
V candle = 196.8731396
V candle ≈ 196.9 cm³
