If 36 is 80% ( a piece) of a number. that means the number must be higher than 36
Changing the English to math:
36 = 80% x n (n being the number)
36= .8n (changed the percent to a decimal by moving it back two places
<u>36</u> = <u>.8</u>n
.8 .8 I divided both sides by .8 - when you divide a number by a decimal (less than one) the number will become larger.
The answer is 45

Step-by-step exAnswer:(-2, 2)
Step-by-step explanation:
7q² - 28 = 0
Add 28 to bothside
7q² - 28 + 28 = 0+ 28
7q² = 28
Divide bothside by 7
7q² / 7 = 28/7
q² = 4
Take the square root of bothside
√q² = ±√4
q = ± 2
q = -2 or q =2
q = (-2, 2)
Answer: y= -1/4x+5

Answer:
<h2>
<em>D</em></h2>
Step-by-step explanation:
She bought gas and candy so solve both to find the answer
She bought 18 gallons of gas and each gallon is 2.66
18*2.66= 47.88
So total 47.88 dollars for gas
And two candy bars so
1.46*2= 2.92
Add the two costs together
2.92+47.88= 50.80
$50.80
D is the answer because you have to divide to find it
