Answer:
60 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
For Plan A
Plan A charges $35 plus $0.25 per minute for calls.
$35 + $0.25 × x
35 + 0.25x
For Plan B
Plan B charges $20 plus $0.50 per minute for calls.
$20 + $0.50 × x
20 + 0.50x
For what number of minutes do both plans cost the same amount?
This is calculated by equating Plan A to Plan B
Plan A = Plan B
35 + 0.25x = 20 + 0.50x
Collect like terms
35 - 20 = 0.50x - 0.25x
15 = 0.25x
x = 15/0.25
x = 60 minutes.
Hence, the number of minutes that both plans cost the same amount is 60 minutes

Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.

Answer:
Step-by-step explanation:
Given
<em>(You and 3 friends)</em>
per individual
Required
Determine the change
First, we need to determine the total amount spent on movie ticket.
The question does not state whether I pay for my friend's ticket.
So, we'll work on what is obvious.
i.e
Add this amount to the amount spent on popcorn
To get the Change, we have to deduct the total amount spent from the amount given by mom
Hence:
The change is $10.25
11. 5.63 | 56.3 | 563. 14. 10^2 | 4.2 | 42
