60% of 15 is what answer

Answers

The correct answer is 9. :)

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.

Someone buys 6 cakes for 8$ each he sells them for ten each then he got 8 more and selled them for 10$ how much money does he have left???

Answers

Answer: $28

Step-by-step explanation:

The person bought 6 cakes for $8 which reduces his money by:

= 6 * 8

= -$48

He then sells them for $10 each so the money made was:

= 10 * 6

= $60

He then buys 8 more for the same price which will reduce his money by:

= 8 * 8

= -$64

He sells these 8 for $10 so the money made was:

= 8 * 10

= $80

Total money left is therefore:

= 60 + 80 - 48 - 64

= $28

angle A and angle B are supplementary angles. If m angle A = (2x + 26)° and m
angle B = (x + 25)°, then find the measure of angle B.


x=43

Answers

Answer:

m angle B = 68°

Step-by-step explanation:

Since they are supplementary, they add up to 180°

(2x+26) + (x+25) = 180

add like terms together

3x+26+25=180

simplify the left side

3x+51=180

subtract 51 from both sides

3x=129

divide both sides by 3

x=43

Then you plug in x into measure B

(43)+25

68
