Answer:
Step-by-step explanation:
t + u = 11 ----------- (1 )
10t + u = 10u + t - 9
10t + u - 10u - t = -9
10t - t + u - 10u = - 9
Combine like terms
9t - 9u = -9
Divide the entire equation by 9
t - u = -1 --------------(2)
Add equation (1) & (2) and so, u will be eliminated and we can find the value of t
(1) t + u = 11
(2) <u>t - u = -1</u>
2t = 10
t = 10/2
t = 5
Plugin t = 5 in equation (1)
5 + u = 11
u = 11 - 5
u = 6
The original number is 56
Answer:
D
Step-by-step explanation:
Volume of a cylinder is equal to the area of the base circle times the height of the cylinder.
The area of your base circle is where r=15 and they are using
as 3.14.
So we have the area of your base circle is inches squared.
Now to find the volume of a cylinder again you just multiply your base area by your cylinder and you get:
cubic inches
