Answer: immy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy must determine c, the amount of change in dollars he should give the customer. Which equation represents c?

20 minus 0.75 c = 9

20 minus 0.75 = 9 c

0.75 (9) + c = 20

0.75 c + 9 = 20

C / 0.75 (9) + c = 20

Step-by-step explanation:

To find your change, first you must determine how much the customer is paying. To find this, you must multiply the cost of one book by the number of books bought.

Step-by-step explanation:

find the value of x.

Answers

Answer:

x = [tex]\sqrt{87}[/tex]

Step-by-step explanation:

if you draw a perpendicular segment from the vertex between sides 5 and 16 to the opposite side then you have a right triangle and can use the Pythagorean Theorem,  a² + b² = c²

a = x

b = 13 (you get this from 18 - 5)

c = 16

x² + 13² = 16²

x² + 169 = 256

x² = 87

x = √87

3-22.5

7-52.5

please mark as brainliest!!<3

Answer:

15 : 22.5 : 52.5

Step-by-step explanation:

2+3+7 = 12units

To find how much kg one unit is.

90kg ÷ 12units = 7.5kg/unit

2units : 7.5 x 2 = 15kg

3units : 7.5 x 3 = 22.5kg OR 22/1/2 kg

7units : 7.5 x 7 = 52.5kg OR 52/1/2 kg

Therefore, the answer is

15 : 22.5 : 52.5
