Answer:
It will take 100 additional minutes for the two plans to cost the same.
Step-by-step explanation:
Tim is choosing between two cell phone plans, Cingular and Verizon. They offer the same amount of free minutes.
Cingular's plan charges $39.99 per month with additional minutes costing $0.45.
Verizon's plan costs $44.99 with additional minutes at $0.40
Let a = the number of additional units that it will take the two plans to cost the same.
This means total cost of Cingular's plan additional minutes will be 0.45a and total cost of Verizon's plan additional minutes will be 0.4a
For the two plans to cost the same,
39.99 + 0.45a = 44.99 + 0.4a
0.45a - 0.4a = 44.99 - 39.99
0.05a = 5
a = 5/0.05 = 100
Answer:
The perimeter of the square would be 8x - 16.
Step-by-step explanation:
Since the sides of the square all the same, you can just multiply the length of one side by 4 to find the perimeter. The perimeter is the distance around an object.
4( 2x - 4 ) = 8x - 16
Step-by-step explanation:
Given
3 (t + 4 ) = 25.5
t + 4 = 25.5 / 3
t + 4 = 8.5
t = 8.5 - 4
t = 4.5
Hope it helps :)
I don’t know how to solve this but I think u have to use the fractions with the other numbers and multiply them then divide
