Answer:
x = 5, y = 3
Step-by-step explanation:
<u>Elimination method: (I will be eliminating 4y) </u>
3x + 4y = 27 --- Equation 1
x + 4y = 17 --- Equation 2
Equation 1-2: 3x + 4y - x - 4y = 27 - 17
2x = 10
x = 10 ÷ 2
x = 5
Substitute x = 5 into Equation 2:
x + 4y = 17
4y + 5 = 17
4y = 17 - 5
= 12
y = 12 ÷ 4
y = 3
3:5
3+5=8
82÷8=10.25
3(10.25):5(10.25)
30.75:51.25
the answer is 30.75:51.25
Yes the answer is A. Good job!!!
Answer:
2π r(15 + r ) = 650
Step-by-step explanation:
The formula for TSA of cylinder is 2πr (r +h)
so
The correct equation is
2π r(15 + r ) = 650
hope it helps :)
10 1/2
10.5 = 10 5/10
but 5/10 can be simplified to 1/2
the answer is 10 1/2
