Answer: x = 6
explaination:
ac= 2ao
ao=3 so ac= 2(3) which is six
so 5x-24=6
x=6
surface area of cylinder = 2 π r h + 2π r²
plug in values of pi, radius and area
2,461.76 = 2× 3.14 × 14 × h + 2× 3.14 × 14 × 14
2,461.76 = 87.92 h + 1,230.88
2,461.76 – 1,230.88 = 87.92h
1,230.88 = 87.92h
1,230.88 ÷ 87.92 = h
h = 14 ft
The answer is A or it should be
Answer:
Step-by-step explanation:
Given that,
y=x+2 equation 1
2x-y=-4 equation 2
This is a simultaneous equation.
Substitute equation 1 into equation 2
2x-y=-4. Since y=x+2
2x-(x+2) = -4
2x-x-2 = -4
x-2 = -4
x = -4+2
x = -2
Also from equation 1
y=x+2
Since x=-2
y=-2+2
y=0
Then, solution (x, y) = (-2,0)
