Lol no one is going to work that out just copy and paste into an online calculator good luck
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

Hi there!
Your answer is:
0+ 10i!
I takes away the negative. √100 is equal to 10
Answer:
B) 8x - 20 + 2x = 11
Step-by-step explanation:
4(2x - 5) + 2x = 11
use pemdas
parenthesis comes first
open the parenthesis
4 * 2x - 4 * 5 + 2x = 11
8x - 20 + 2x = 11
