Z--3/4=6 1/2

Help I have homework

Answers

Answer 1

Answer: In my opinion, it is easier to use decimals than fractions, so first we are going to rewrite this equation with decimals instead of fraction values.

z - 0.75 = 6.5

To simplify this equation, we are going to add 0.75 to both sides of the equation, to cancel out this value on the left side.

z= 7.25

Your final answer is=7.25 or 7 1/4

Answer 2

Answer: two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4

Callie has 83 postcards in her collection. Of the postcards, 24 are from Canada. The rest of the postcards are from United States. How many of the postcards are from the United States?

Answers

59 of the post cards were from the United states. Just subtract 24 from 83

Final answer:

By subtracting the number of postcards from Canada from the total collection, we find that there are 59 postcards from the United States.

Explanation:

The subject of this problem is subtraction in math. We know that Callie has 83 postcards in total, and 24 postcards are from Canada. The rest are from the United States. We can find out how many postcards are from the United States by subtracting the Canadian postcards from the total collection. So, 83 (total) - 24 (Canadian) = 59 postcards are from the United States.
