Answer:

-1.2

Step-by-step explanation:

15x+20−2.5x=2.5x+5−2.5x

12.5x+20=5

12.5x+20−20=5−20

12.5x=−15

12.5x /12.5  =

−15 /12.5

x=−1.2

Answer:

x=-1.2

Step-by-step explanation:

<u>Question: 15x+20=2.5x+5</u>

1) Subtract 2.5x from both sides:

12.5x+20=5

2) Subtract 20 from both sides:

12.5x=-15

3) Divide both sides by 12.5:

x=-15/12.5

4) Write the fraction as a decimal:

x=-1.2

The area of a square is 72.25 inches squared. Find the length of the side and the perimeter.
Darina [25.2K]

Area of the square = 72.25

side^2 = 72.25

side = \sqrt{72.25}

Side = 8.5 in

Perimeter = 4 × side

Perimeter = 4 × 8.5 in

Perimeter = 34 in

How does 0.03 compare to 0.003
kati45 [8]

0.03 compare to 0.003

While comparing decimals we write the decimals one below the other according to the place value of each digits in place value chart

ones -- point -- Tenths -- Hundredths -- Thousandths

 0          .             0              3

 0          .             0              0                      3

Now we compare each digit left to right. We have 3 in hundredths  and 0 in hundredths place. 3 is greater

So 0.03  is greater than  0.003

0.03 > 0.003

Please please help I really need it today please show work
Cerrena [4.2K]

Answer:

<u><em>x=9</em></u>.

<em><u>perimeter=68</u></em>

<em><u>area=168</u></em>

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to  multiply the length and the width so 28x6 which is <em><u>168</u></em>.

hope that helped :)

Maria's account has a credit of $ 13, and Harry's account has a debit of $ 14. Which of the following statements are true? Selec
soldi70 [24.7K]

Answer:

A, Harry has $27 more.

Step-by-step explanation:

I could be wrong but.

1) debit cards are of your money, if you have $14 in your account it means you have $14 that you can spend without owing anything.

2) credit cards allow you to borrow money with the expectation that you pay it back. So if you have $13 of credit, you owe $13 which I guess could be seen as -$13.

3) the distance between -13 and 14 is 27.
