On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
nikitadnepr [17]

Answer:

The percent change is -7%.

Step-by-step explanation:

In order to find the answer, you can use the following formula:

Percent change=(New value-Old value/Old value)*100

New value=71-5=66

Old value=71

Now, you can replace the values on the formula:

Percent change=(66-71/71)*100

Percent change=(-5/71)*100

Percent change=-0.07*100

Percent change=-7%

According to this, the answer is that the percent change is -7%.

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of
KiRa [710]

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

\frac{L}{W}=\frac{5}{3}

Where:

  • L represents the new length
  • W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

L=18-x

W=12-x

Then, we will have:

\frac{18-x}{12-x}=\frac{5}{3}

Finally, we just need to solve it for x.  

3(18-x)=5(12-x)

5x-3x=60-54

2x=6

x=3

<u>Therefore, the value of </u><u>x = 3.</u>

I hope it helps you!
