The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are

rented. Which expression can be used to find the cost in dollars of renting ice skates

for h hours?

A)4h + 3.5

B)3.5 - 4h

C)3.5(h+4)

D)3.5h+4

D)3.5h+4

Step-by-step explanation:

Let h denotes the number of hours that the ice skates are  rented.

Since, The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are  rented.

So , the total cost for ice-skating = $4 + $3.50 x (number of hours that the ice skates are  rented.)

= 4+3.50 x ( h) [as expression]

Hence, the expression can be used to find the cost in dollars of renting ice skates for h hours :-

282 6/7 cm^2

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
