Answer:
-11°C
Step-by-step explanation:
Original Temp = -2°C
Temp Drop (i.e temperature is reduced by) = 9°C
Final Temperature,
= Original Temp - Temp Drop
= -2°C - 9°C
= -11°C (Ans)
Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
Answer:
x = 5
Step-by-step explanation:
15 / 3 =5
Step-by-step explanation:
from,
An = 4n -13
A1 = 4 (1) - 13
> A1 = -9
A2 = 4(2) - 13
> A2 = -5
A3 = 4(3) - 13
> A3 = -1
A4 = 4(4) - 13
> A4 = 3
You would do 150/15=10 since this is a percent change it to a decimal(.10) to check do 150x.10=15 and 15/.10=150
