Answer:
$3.15
Step-by-step explanation:
At $2.10 for 70 slices, the rate is apparently 3¢ per slice. That rate multiplied by 105 slices gives $3.15.
The correct answer should be C to this question

Step-by-step explanation:
−2x - y = 9
x-intercept → Plug in 0 for <em>y</em><em> </em>to get −4½ for <em>x</em>
y-intercept → Plug in 0 for <em>x</em><em> </em>to get −9 for <em>y</em>
−2x - y = 9
+ 2x + 2x
_________

<em>Slope-Intercept</em><em> </em><em>Form</em>
_______________________________________________
x + 5y = 5
x-intercept → Plug in 0 for y to get 5 for x
y-intercept → Plug in 0 for x to get 1 for y
x + 5y = 5
- x - x
_________

<em>Slope-Intercept Form</em>
_______________________________________________
3x - 4y = 12
x-intercept → Plug in 0 for y to get 4 for x
y-intercept → Plug in 0 for x to get −3 for y
3x - 4y = 12
- 3x - 3x

Answer:
Step-by-step explanation:
Let the equal number of hours be represented by variable H;
The two equations will be as follows;
Jack; 40 +30H
Mark; 50 +25H
Next, equate them;
40 + 30H = 50 + 25H
30H - 25H = 50 - 40
5H = 10
H =10/5
H = 2hrs
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30H = 40 + (30*2)
=40 + 60
= $100
