Answer:
x = 11
Step-by-step explanation:
The given angles are supplementary which means their sum is 180
8x - 6 + 98 = 180 add like terms
8x + 92 = 180 subtract 92 from both sides
8x = 88 divide both sides by 8
x = 11
Answer:
4
Step-by-step explanation:
You'll want to construct your question into an equation:
18 = 3(2+N)
Use distributive property
18 = 6 + 3N
Put 6 on other side and subtract
3N = 12
Divide and simplify
N = 4
Answer:
Step-by-step explanation:
-60
Step-by-step explanation:
Increase in population is given by positive sign
Change in population in 5 years = -300
Decrease in population is represented by negative sign
Change in population in 1 year = -300\5
= -60
Town's population faces a decrease of 60 residents each year.
Answer:
Step-by-step explanation:
V= π(8)^2(12/3)
V= 64(4)π
V= 256π
V= 804.3 cm^3
Answer:
30 years
Step-by-step explanation:
Shobo's age=x years
His mother's age= 6 times of Shobo's age= 6x years
Five years from now
Shobo's age= (x+5) years
According to the problem
x+5=1/3 of his mother's present age
x+5=6x/3
x+5=2x
5=2x-x
5=x
Therefore Shobo's present age is 5 years
His mother's age =6x
6x5=30 years
