Option B is correct
Step-by-step explanation:
We need to find the solution to system of equations

Let:

Putting value of y from eq(2) into eq(1)

So, value of x=7

This is a fraction equal to
7 yards ÷ 4 dresses
We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.
7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)
Hope I helped! :)
        
             
        
        
        
.8 (88%)+.2x=90%
70.4%+.2x=90%
subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
