60= 100%
- 60% = tacos
=============
60x.60=36
60-36= 24
24x.25=6
6 orders were for other items.
5x-5=-7y
3x+2y=-8
First, you need to rearrange the first equation so it is in the same format as the second one.
5x-5=-7y
Add 5 to both sides
5x-5+5=-7y+5
Add 7y to both sides
5x+7y=-7y+7y+5
So you have 5x+7y=5
Now you need to multiply that equation by 3
3(5x+7y=5)
15x+21y=15
Multiply the second equation by -5
-5(3x+2y=-8)
-15x-10y=40
Now add them together
15x+21y=15
+(-15x-10y=40)
---------------------
11y=55
y=5
Now plug y=5 into one of the original equations and solve for x.
3x+2(5)=-8
3x+10=-8
3x=-8-10
3x=-18
x=-6
To check the solution plug them both into the other equation:
5(-6)-5=-7(5)
-30-5=-35
-35=-35
It checks.
Hope that helps.
Ac - 5ad - 5bc + 25bd = a(c - 5d) - 5b(c - 5d) = (c - 5d)(a - 5b)
Answer:In order to calculate the volume of a composite figure, first you separate the two figures.Then, find the volume for each figure by multiplication.Lastly, add the volumes of the two shapes.
