Answer:
After 3 visits both plans will cost the same.
Step-by-step explanation:
Gym A costs $26.76 plus an additional $4 for each visit. 
Gym B has no initial fee but costs $12.92 for each visist.
The cost for gym A can be written as 
C= $26.76 + 4(x)  where x is the number of visits to the gym A
The cost for gym B can be written as 
C= $12.92 (x)  where x is the number of visits to the gym B
Both costs will be equal 
12.92x= 26.76 +4x
12.92x-4x= 26.76
8.92x= 26.76
x= 26.76/8.92
x= 3
after 3 visits both plans will cost the same.
Check 
12.92x= 26.76 +4x
12.92*3= 26.76 +12
38.76= 38.76

Answer:
2.5cm
Step-by-step explanation:
area of a trapeziod = 1/2 (a+b)×h
a=1cm
b=5cm
h=?
area= 7.5cm^2
••••• 7.5cm^2=1/2 (6)h
7.5= 3h
then height = 7.5/3= 2.5cm
