Elanso [62]

When Kimai is making blankets for charity, the proper form of the unit rate is 4 hats per hour.

<h3>How to calculate the value?</h3>

From the information given, it was stated that Kimai is making blankets for charity. In order to determine how many hats she can make per hour, she created 3/5 of the hats in 1/8 of an hour.

Therefore, the proper form of the unit rate will be:

= Amount of hats / Time

= 3/5 ÷ 1/8

= 3/5 × 8/1

= 4.8

Therefore, the proper rate will be 4 hats per hour.

13) -4= -b -1/3b and -23/3= 1/2a + 5/3a
Sergeeva-Olga [200]

-4=-1b-(1/3)b

-4=-(4/3)b

-4/-(4/3)=b

b=3

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

(1/2)3+(5/3)2

3/6+10/6=13/6

-23/3=13/6a

(-23/3)/(13/6)=a

a=-46/13
