First, set up your equation.
_(x+4)_ = 7
2
multiply both sides by 2 to cross out the 2 on the bottom
_(x+4)_ *2 = 7*2
2
x+4 =14
subtract 4 from both sides
x+4= 14
-4 -4
x=10
A solution to a equation is when the variable is substituted fully. That makes the equation true.
Y = 3(x + 2) + 4
Y = 3x + 6 + 4
Y = 3x + 10
Answer:
221 cubic metre.
Step-by-step explanation:
Volume of water in tank (v) = π × {3}^{2} × 6
= 54π cubic metre
Volume of tank (v') = π × {5}^{2} × 11
= 275π cubic metre
More Water that can be fit in the tank = v' - v
=275π - 54π
= 221π cubic metre.
