Answer:
2. x/-5 = 22
3. Multiply both sides by -5
4. x = -110
Step-by-step explanation:
The initial cost is $45. To determine the increase, you need to follow two steps.
First you have to find what 7% of the original $45 is. This will tell us how much the cost will increase by.
To find 7% of $45, you need to multiply .07 x 45 = 3.15
This tells us that 7% of $45 = $3.15
Next, you have to add the increase to the original cost. This will be the new monthly cost.
$45 + $3.15 = $48.15
From the first 2 statements again , x + 8 = y.
area of the hole would be 4x cm^2
area of sheet without hole is 9y cm^2
9y - 4x =76 ------------- eqn one
y = x + 8 ----------------eqn two
subs eqn two into one and u got it
