Answer:
Step-by-step explanation:
Wut bob has 4 die you should i have 1 kill in a foot face
Steps:
let “x” be number of hrs
let “y” be total cost
Abe:
50x + 75 = y
Plumbing Service:
65x=y
Since both equations are equal to y, you can set them equal to each other.
65x = 50x + 75
isolate for x:
65x - 50x = 75
15x = 75
x = 5
therefore it will take 5 hours for each to cost the same. you should call Abe for any task more than 5 hours because it will be cheaper and you should call the Plumbing Service for any task less than 5 hours because it will be cheaper.
Answer:
x = 18
Step-by-step explanation:
Since both right triangles are similar, therefore:

Cross multiply




Subtract 780 from both sides





x + 23 = 0
x = -23
Or
2x - 36 = 0
2x = 36
x = 18
Answer:
The average time to commute to work is 25 minutes.
Step-by-step explanation:
If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.
The answer is 1/2 because if you draw 1/2 and 1/3 I will see 1/2 is bigger
