For this one you have to make the equations. And what I like to do is write it out, like this.One Week- $473 suits 1 shoes (pairs)
Another Week- $1077 suits 2 shoes (pairs)
Then I make/choose my variables.For suits, it's going to be x.And For shoes let's do y.(Or if you would like better you can do x and y, which ever works best for you)
Now for the equations:One Week, 47= 3x +1yAnother Week, 107= 7x + 2y
Now it's time for the Substitution! Your last problem had it easier because it was already in the form, y=mx+b, but since ours aren't we have to change it to y=mx+b.
One Week, -0.33y + 15.67 =x Another Week, -0.29y + 15.29 =x
Now you can use substitution. :)For y i got 9.5 or 9.50.For x, i got 12.34
So the answer is (9.5,12.34) or (12.34, 9.5)
Answer:
x= -4
Step-by-step explanation:
1. Add 5 to both sides. So x=5. That is a vertical line. The answer is undefined
2. 25- 5 7/8 + 6 1/2
Denominators have to be the same
Multiply 1/2 by 4/4
25-5 7/8 + 6 4/8
25 - 11 11/8
23 16/8- 11 11/8
12 5/8
