Answer:
Step-by-step explanation:
10x-9y=24....(1)
y=x-2...(2)
Substitute (2) into (1)
10x-9(x-2)=24
10x-9x+18=24
x+18=24
Substrate 18 from both sides
x=6
Substitute the value of x in (2)
y=6-2
y=4
When x=6,y=4
Cylinder: 1²(3) = 3
3(9) =27
Prism: 4x3x6 =72
Total: 72+27 = 99in³
Answer:
X=-4, y=-7
Step-by-step explanation:
6x-5y=11. 1st equation
y=7x+21 2nd equation
6x-5(7x+21)=11. Sub value of y in 2nd equation (7x+22) into 1st equation
6x-35x-105=11. Solve by distributative property
-29x-105=11. Add x values
-29x=116. add 105 to both sides
x=-4. Solve for x
solve for y:
y=7x+21
y=7(-4)+21
y=-28+21
y=-7
check answer by substituting x and y into either equation
6x-5y=11
6(-4)-5(-7)=11
-24+35=11
11=11
