Answer:

C. 2A/b

Step-by-step explanation:

The given formula is

$A=\frac{1}{2}bh$

We want to solve the given formula for h.

Multiply both sides by 2.

$2A=bh$

Divide both sides by b.

$\frac{2A}{b}=h$

$h=\frac{2A}{b}$

Last Month, Levi had written 125 words of his book. This month,he is up to 12,580 words. About how many times more words has he

VladimirAG [237]

Answer:

He has written about 100 times as many words.

Step-by-step explanation:

In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.

12,580 - 125 = 12,455

Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.

12,455/125 = 99.64 times more, or rounded, about 100 times more.

5 1/4 - 2 2/3, how do I solve please?

densk [106]

5 1/4 - 2 2/3

first you find the LCM, so u can make both fractions have a like denominator. I'm thinking the LCM is 12, so:

(5 3/12) - (2 8/12)
= 63/12 - 32/12
=31/12
= 2 and 7/12

5 1/4 - 2 2/3 = 2 7/12
