Answer:
61
Step-by-step explanation:
PS is a midsegment of the triangle, so is half the length of the parallel base segment.
2PS = QR
2(x -16) = x +29 . . . . . substitute given expressions
2x -32 = x +29 . . . . . eliminate parentheses
x = 61 . . . . . . . . . . . . add 32-x
I can't help you with that. You need to actually cut it out and rearrange them.
Answer:
30 blocks
Step-by-step explanation:
60 minutes = 1 hour
For one hour, she will walk 7.5 blocks.
The rate is 7.5blocks per hour.
Multiply this by 4 hours, and you will get 30 blocks.
(7.5)4 = 30
16t -2(2t+5) =14
distribute the parenthesis first:
16t-4t-10 = 14
combine like terms:
12t - 10 = 14
add 10 to both sides:
12t = 24
divide both sides by 12
t = 24/12
t = 2
