Answer:

15^4+2^3−8^2−22−15

Step-by-step explanation:

(3^2−2−3)(5^2+4+5)

Distribute:

<u>3(5^2+4+5)</u> ⋅ ^2−2(5^2+4+5) − 3(5^2+4+5)

15^4+12^3+15^2 <u>− 2(52+4+5)</u> − 3(52+4+5)

15^4+12^3+15^2 − 10^3−8^2−10 <u>− 3(52+4+5</u>)

15^4+12^3+15^2 − 10^3−8^2−10 − 15^2−12−15

Combine like terms:

15^4<u>+12^3−10^3</u>+15^2−8^2−15^2−10−12−15

15^4+2^3<u>+15^2−8^2−15^2</u>−10−12−15

15^4+2^3−8^2<u>−10−12</u>−15

15^4+2^3−8^2−22−15

15^4+2^3−8^2−22−15

hope it helps :)

Change 0.7 to a common fraction
erma4kov [3.2K]

Answer:

7/10

Step-by-step explanation:

In 0.7 we will change the decimal to fraction. First we will write the decimal without the decimal point as the numerator. Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number. Therefore, we observe that 0.7 (decimal) is converted to 7/10 (fraction).

a store marks up the wholesale price of a skateboard by 112%. The retail price is $35. What is the wholesale price of the skateb
koban [17]
Answer is $31.25
Step by step
We know mark up is 112%
We know sell price (retail) after markup
We are looking for wholesale (original price)
So 112% of x = $35
1.12x = $35
Divide both sides by 1.12 to isolate x
X= 31.25

Solve for x: 3|x − 3| + 2 = 14
vaieri [72.5K]

Answer:

x = 7                      x = -1

Step-by-step explanation:

3|x − 3| + 2 = 14

Subtract 2 from each side

3|x − 3| + 2 -2= 14-2

3|x − 3|  = 12

Divide by 3

3|x − 3| /3 = 12/3

|x − 3| = 4

Now the absolute value has a positive and negative solution.

x-3 = 4      x-3 = -4

Add 3 to each side

x-3+3 = 4+3      x-3+3 = -4+3

x = 7                      x = -1
