Okay, so what you need to figure out is that how many years in between 21 1/4 and 37 there are based on the amount the tree grows a year. So, 1 3/4 times 9 is 15.75, and this added to 21 1/4 is 37. This means that it will take the tree 9 years to grow from 21 1/4 ft to 37 ft.

Last week at a​ festival, a man sold 5 times as many​ tie-dyed T-shirts as​ silk-screened shirts. He sold 228 shirts altogether.
kumpel [21]

Answer:

The man sold 190 tie-dyed T-shirts

Step-by-step explanation:

This problem can be modeled by a system of equations.

I am going to call x the number of tie-dyed T-shirts that the man sold and y the number of silk-screened shirts that he sold.

We have that he sold 5 times as many tie-dyed T-shirts as silk-screened shirts. So this gives us our equation 1)

1) x = 5y.

We also know that altogether, he sold 228 shirts. So this gives us our equation 2)

2) x + y = 228.

Now, we solve the system formed by equations 1) and 2)

x = 5y

x + 5y = 228

6y = 228

y = 38

x = 5*38

x = 190

So, in all, the man sold 190 tie-dyed T-shirts and 38 silk-screened T-shirts.

So basically your gonna regaurd 63.5 as 60 +3.5, 60 is 5*12 and the remaining 3.5 is less than the divisor 5, so it would be the remainder 
anwser is 63.5/5 treat as 60/5+3.5/5
so anwser is 60/5+3.5/5=0.7=12.7
