Answer:
or 9/20x + 12
Step-by-step explanation:
We can start by grouping like terms:
3/5x - 3/20x + 19 - 7.
We can add similar elements:
9/20x + 19 - 7.
Multiplying gives:
9x/20 + 19 - 7.
Adding and subtracting:
9/20x + 12
A=#nickels, b=#quarters
5a + 25b = 410 total value
5(a + 5b) = 410
a + 5b = 82
a + b = 30 total no. of coins
subtracting . . . 4b = 52
thus b = 13 and a = 17
13 quarters and 17 nickels = 13*25 + 17*5 = 410 = $4.10
Fish=8*parakeet, p=parakeet
f+p=63 ounces
8p+p=63
9p=63
p=63/9=7 oz
f=8*7=56 oz
