-3.5 * 2 = -7
-3.5 * 3n = 10.5n
So there is (-7 - 10.5n) -2.5n
Now combine like terms
10.5n - 2.5n = 8n
ANSWER = -7 + 8n
Answer:
haircut =9 and hair color= 3
Step-by-step explanation:
Step one:
GIven data
let the haircut be x
and hair color be y in numbers.
so
18x+42y=288------------1
x+y=12---------------------2
from 1
x=12-y, put this in 2, we have
18(12-y)+42y=288
216-18y+42y=288
collect like terms
24y=288-216
24y=72
divide both sides by 24
y=72/24
y=3
put y= 3 in 2
x+3= 12
x= 12-3
x=9
Answer:
The height is 15 m.
Step-by-step explanation:
V = (pi)r^2h
375(pi) = (pi)(5^2)h
Divide both sides by 25pi.
15 = h
Answer: The height is 15 m.
