They will make 70 dollars
50/5 = 10 so they make 10 dollars an hour 8 - 1 equals 7 so 10 times 7 hours is 70
The answer is 4 miles and hour because at the x it is the amount of hours and 4 y falls on the line above it
X = 34/cos27° = 34/0.891 ≈ 38.16
Answer:
Eighteen and five-hundred thirty-three thousandths
To put simple like this
add as normal
2+2=4
add if were positive but keep it negative
-2+-2=-4
at this point it basically turns in to a subtraction problem
2+-2=0
here is another way to look at it. two positives (+) and two negatives (-)
+ +
- -
if there is a negative under it, it is canceled out.
in this there are 5 positives and 3 negatives. each negative will cancel one positive leaving +2 left
+ + + + +
- - -
hope that explains it some what.
