Yky. we'd to provide the other options but to do this you need to +14 to both side. 21+14 then -14+14 cancel. so it's now

7x=35 then you divide 7 in both sides 7 cancels 35/7 =5

x=5

Concentrate and water are mixed to make juice. Which is the stronger
vladimir1956 [14]

Answer:

As a fraction, A is 3/8 concentrate in final product and B is 4/11.

A is, in other words, 33/88, and B is 36/88 concentrate in the final mixture.

So Mixture B is stronger, slightly.

Note that in order to make the fractions the same denominator, we had to 'expand' each fraction with the denominator of the other fraction. After that, the numbers are really easy to compare.
