Answer:
f = -3/4
Step-by-step explanation:
13f + 6 -f = -3
Combine like terms
12f +6 = -3
Subtract 6 from each side
12f+6-6 = -3-6
12f = -9
Divide each side by 12
12f/12 = -9/12
f = -3/4
Answer:
(-5,2) (-7,0)
Step-by-step explanation:
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
Given:
uniforms in a package of 8.
127 people with 3 uniforms each.
127 x 3 = 381 uniforms
381 ÷ 8 = 47.625 ⇒ 48 packages
The store will need to order 48 packages of uniforms to fulfill the uniform requirement of 127 people. There will also be 3 uniforms left in excess of the 48 packages.
48 * 8 = 384
384 - 381 = 3 excess uniform
