Answer:
Step-by-step explanation:the diagonals of a parallelogram bisect each other
S=sodas h=hotdogs
228=s+h
s=3h
228=3h+h 228=4h h=57
228=s+57 s=171
Answer: 171 sodas and 57 hotdogs were sold by the vendor
7/2 = 3 1/2
16/4 = 4
17/3 = 5 2/3
18/2 = 9
22/8 = 2 3/4
21/9 = 2 1/3
Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
