Step-by-step explanation:
Parallel lines always have the same slope.
Answer:
C. In step 2, Cindy should have multiplied both sides of the equation by 2.
Step-by-step explanation:
I'll go through the equation correctly, and then point out what would have happened.
3 = x/2 - 5
Add 5 to both sides. -5 and 5 cancel out.
8 = x/2
What Cindy should have done here is multiply by 2, not divide by 2. It is important to remember that you do the INVERSE operation to cancel out a number.
What would have happened here is that we have an extra step (though either way we still end up with x being 16.)
Correct Step 2:
Multiply both sides by 2. x/2 and 2x cancel out.
x = 16
Incorrect Step 2:
8/2 = (x/2)/2
4 = x/4
Multiply both sides by 4 (this would be the extra step!).
16 = x
Answer:
$50.50
Step-by-step explanation:
From the above question, we are to find the total cost of the tickets Mr Montes bought
An adult ticket to the school play cost $14.75.
A child ticket cost $5.25.
Mr. Montes bought 2 adult tickets and 4 child tickets.
Hence, the total cost is
= 2 × $14.75 + 4 × 5.25
= $29.5 + $21
= $50.50
