Answer:
DE = 81
Step-by-step explanation:
The sides of a rhombus are congruent , thus
9z = z + 72 ( subtract z from both sides )
8z = 72 ( divide both sides by 8 )
z = 9
Then
BC = 9z = 9 × 9 = 81
Since the sides are congruent, then DE = 81
Answer:
Lin ran at 2.9 meters per second. She can run 174 meters in a minute (2.9 times 60)

Answer:
$6.99 for each memory card.
Step-by-step explanation:
she paid a total of 127.35 for everything including sales tax.
if the camera cost 6 times more than the case you will first divide 91.98 by 6
91.98/6 = 15.33 total cost of the case
so now you subtract your camera, case and sales tax from the total amount she paid which is 127.35
127.35 - 91.98 - 15.33 - 6.06 = 13.98 is left to find the price of each memory card you divide 13.98 by 2
13.98/2 = 6.99
