Answer:

Step-by-step explanation:

This may seem quite obvious but study! Math is said to be one of the hardest subjects, in middle, high school, and college. Thus, it is very important you are good at it; considering it will be essential in many cases in life. I'd suggest:

Doing your homework and assignments
Try some practice problems so you could get the gist of what is being asked of in the question
Try some online tests, quizzes, or lessons

Here's a tip:

Ask for help if you need it! It is important that you really understand everything, every little detail matters. Good luck!

Look at the pair of equivalent expressions. 36 + 8 = ?(9 + 2) What number is missing from the expression?

JulijaS [17]

Answer:

? = 4

4 is the number missing on the right.

Step-by-step explanation:

Check out the 8 on left. It has become a 2 on the right. How did that happen?

What do you have to multiply the 2 by to get 8?

Before I answer, check out the 9 on the right. What did you have to multiply it by to get 36? The answer to that is 4 isn't it?

What about the 2. Don't you have to multiply it by 4 to get 8?

36 + 8 = 4(9 + 2) The distributive property on the right will produce the numbers on the left.

So ? = 4

Can someone explain to me how to get the answer?

kow [346]

Amount = P $(1+ \frac{r}{n}) ^{nt}$

P is the amount you invested.
r is the interest rate in decimal form (so 6% = 0.06)
n is the number of times a year you are paid interest (semiannually = 2)
nt is the number of payment times you expected (4 years, twice a year = 8 times)

Sally is 10 years older than one fifth of her mother’s age. If Sally is 20 years old, how old is her mother?

slamgirl [31]

S = Sally

M = Mother

S = M/5 + 10

20 = M/5 + 10

20 - 10 = M/5

10 = M/5

M = 10 * 5

M = 50

----------------

Her mother is 50 yo

-----------------

50 : 5 + 10 = 20

the answer is good
