She is 3 years older than her brother and has (x+3) in the equation means that x is being used as her brothers age. (She is adding 3 to her brothers age)
The answer is Amy's brother's age.
Answer:
V=πr^2h
pi = 3.14
r = 2
r^2 = 4
h = 10
Multiply all the numbers to get the volume.
Or use the formula.
V = 3.14*4*10
V = 125.6 cubic inches
I am pretty sure that the answer is 4/5, hope this helped :)
9x-5, I guess, not sure, but I'm combining like terms. Hope it's right.
Answer:
x=40
Step-by-step explanation:
Both angles are equal. So the equation needs to equal 156.
Just plug in points for x until the answer is 156.
In this case, when we plug in 40, it works!
