regina bought fruit for her family. she bought 3 1/2 pounds of oranges and 4 and 3/4 pounds of peaches. if she used all bit 1 3/
jeka94
First, you would have to combine 3 1/2 and 4 3/4 pounds. That would be 8 and 1/4 lbs. If she used all but 1 3/8 lbs, you would have to do 8 1/4 minus 1 3/8. That means she used 7 1/8 lbs of fruit. 

The equation would be 3/ 12 + 4 3/4 = 8 1/4 - 1/38 = 7 1/8.

klemol [59]
Answer: 15.7 minutes

Step-by-step explanation:

Let x be the time in the beginning (in minutes).

Given: The track team is trying to reduce their time for a relay race.

First they reduce their time by 2.1 minutes.

Then they are able to reduce that time by 10

If their final time is 3.96 minutes, then

x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7

Hence, their beginning time was 15.7 minutes.

1/2 divided by N equals 1/3<br> what is N?
Veronika [31]

You said that                          (1/2)  /  N  =  1/3

Multiply each side by 'N' :      (1/2)          =  1/3 N

Multiply each side by  3 :        3/2           =        N

                                   or        1-1/2         =       N .
