Answer:
Minutes = 225
Cost = $41.75
Step-by-step explanation:
It is given that:
Cost of Plan A = $8
Per minute cost = $0.15
Let,
m be the number of minutes
A(m) = 0.15m + 8
Cost of Plan B = $17
Per minute cost = $0.11
B(m) = 0.11m + 17
For same cost,
A(m) = B(m)
0.15m+8 = 0.11m + 17
0.15m - 0.11m = 17 - 8
0.04m = 9
Dividing both sides by 0.04

Cost of 225 minutes
A(225) = 0.15(225) + 8
A(225) = $41.75
Therefore,
Minutes = 225
Cost = $41.75

The value of x from the figure is 70°
<h3>How to determine the value</h3>
It is important to note that alternate angles are equal and angles in a triangle sum up to 180°
We then have that,
x + 50 + 60 = 180 °
x + 110 = 180°
Make 'x' subject
x = 180 - 110
x = 70 °
Thus, the value of x from the figure is 70°

maybe the answer is 4 i don't have an computation but it feels 4
Answer:
x = -1
Step-by-step explanation:
3(x+1) = -2(x-1) - 4
3x + 3 = -2x + 2 - 4
3x + 3 = -2x - 2
Add the -2x to both sides
5x + 3 = -2
Subtract the 3 to both sides
5x = -5
Divide both sides by 5
x = -1
