You will do 60/2 to = 30 because the ratio of peaches to cherries is 2:3 and they need to have a unknown number of peaches lets say thats “x” therefore 60/2=x ,x=30 cups of peaches

Find the percent of decrease from 280 to 210. Round to the nearest tenth of a percent, if necessary.

Vlada [557]

To find the decreased percentage,here's what we can do:
$\frac{originl \: value - new \: value}{originl \: value} \times 100\%$

In this case,the eqaution would be:
$\frac{280 - 210}{280} \times 100\% \\ = \frac{70}{280} \times 100\% \\ = \frac{1}{4} \times 100\% \\ = 25\%$
Hope it helps!

$x-\ number\\\\
8x-20=15+x\ \ \ | subtract\ x\\\\
7x-20=15\ \ \ | add\ 20\\\\
7x=35\ \ \ | divide\ by\ 7\\\\
x=5\\\\Number\ is\ 5.$
