x+1 > -5(7-2x)
Use distributive property(Multiply -5 by 7 and -2x).
x+1 > -35 + 10x
Subtract x on both sides so that the variable x is only on one side.
1 > -35 + 9x
Add 35 to both sides so that it cancels out negative 35.
36 > 9x
Divide 9 on both sides so that the only thing remaining on the right side is the variable x.
Final Answer: 4 > x

Helga [31]

Answer:

24 inches.

Step-by-step explanation:

Given:

During a week the water level in a pond decreased by 4 in. Per day,

For two days, it decreased by half that amount = $4\times\frac{1}{2}=2\ inches\ per\ day$

Question asked:

How much did the water level decrease in the pond in one week?

Solution:

As we know, there are 7 days in a week.

For 5 days,

Each day water level decreased by = 4 inches

In 5 days, water level decreased by = $4\times5=20\ inches$

For exceptional 2 days:

Each day water level decreased by = 2 inches

In 2 days, water level decreased by = $2\times2=4\ inches$

Water level decreased in whole week = 20 + 4 = 24 inches

Therefore, water level decreased 24 inches in the pond in one week.
