Shinya went to the salon. The cost if her haircut was $16.00. He tipped the barber 15%. What was the total cost?

Answers

Answer 1
Answer: total cost=costofhaircut+tip
tip=costofhaircut times percent tip
percent tip=15%

percent means parts out of 100
15%=15/100=0.15

cost of haircut=16
tip=16 times 0.15=2.4

total cost=16+2.4=18.4

total cost=$18.40
Answer 2
Answer: $18.40 because 15% of 16.00 is 2.40 so 16.00 + 2.40 = 18.40.

Please help!! -5 = 7 + 3r

Answers

Hi!

-5 = 7+3r

-5-3r = 7+3r-3r

-5-3r = 7

-5-3r+5 = 7+5

-3r = 12

-3r    12
▬ =  ▬
-3      -3

r= -4
R would equal -4. Subtract 7 from each side & youll get -12=3r then divide each side by 3.

Write three different factorizations of the number 16. Do not use 1 as a factor.

Solve for x:-

x + 65 = 120

Thanks!

Answers

x + 65 = 120
    -65      -65

x = 55
To solve for x we will use the INVERSE OPERATION of addition which is subtraction. Lets do it:-

x + 65= 120
x = ?
120 - 65 = x
120 - 65 = 55
x = 55

CHECK OUR WORK:-

x + 65 = 120
x = 55
55 + 65 = ?
55 + 65 = 120
We were RIGHT!!!!

So, x = 55.

Hope I helped ya!! xD
