Answer:
about 19
Step-by-step explanation:
take the elevator weight (1330), subtract the delivery persons weight (140) then divide by the weight of the books (60). It ends up being 19.8333 and so on.
13 divided by 6
5.401×10^-1
You move the decimal over one to get5.401×10^−1
Given:
2x -3 > 11 -5x
Simplify both sides:
2x - 3 > -5x + 11
Add 5x to both sides:
2x - 3 +5x > -5x + 11 +5
7x - 3 > 11
Add 3 to both sides:
7x - 3 +3 > 11 + 3
7x > 14
Divided 7 to both sides:
>
x > 2
