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.
We're are given the following system of linear equations:
What we'll do, is substitute the
in the second equation by the definition of
given in the first equation (
):
We solve for
from the previous equation:
Now we know
.
In order to get the numerical value of
we use the fact that
in the first equation:
So
.
The answer is n=-2 and m=3.
Answer:
B
Step-by-step explanation:
In 45 45 90 triangles the ratio is a:a:a root 2 so the answer would be 3root 2/2 or c because when multiplied again by root 2 it will get you 3.
