Given
Rob is twice Joshua's age
Nick is 5 years older than Joshua.
sum of all their ages is 45.
Find the age of nick.
To proof
As given
Rob is twice Joshua's age
let Joshua's age = x
than Rob age = 2x
Nick is 5 years older than Joshua.
Nick age = 5 + x
sum of all their ages is 45
than the equation becomes
Joshua's age + Rob age + Nick age = 45
put the value
x + 2x + 5 + x = 45
4x = 40
x = 10
Joshua's age = 10 year
than Rob age = 20 year
Nick age = 5 + 10
= 15year
Hence proved
(Mass) 2160g (Divided by) / (Volume) 240cm (Equals) = 9 (Density)
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
When you increase the x-value by one, the y-value decreases by 2. If you decrease the x-value by 1 which would be 0, then add 2 to the y-value which is 10, that would be the y-intercept
Area = LW + 1/2 b * h Subtract L*W from both sides.
Area - LW = 1/2*b*h Multiply both sides by 2
2*Area - 2*LW = b*h Divide by h
