2 x 103 = 206, 8 x 105 is 840.
840 is roughly 4.08 times greater than 206.
24 x 0.25
6
24+6
30
so the answer is £30
Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:
50 + 40x = 30 +45x
Subtract 30 from both sides:
20 + 40x = 45x
Subtract 40x from both sides:
20 = 5x
Divide both sides by 5
x = 4
The length is 4 hours.
It should be "A"
On the number line, it shows that -4.5 is further and to the right of -2.3.
Hope that helps!
