3 casseroles feeds 15 people
The ratio is 3:15
If you divide each of those by 3, youll find that 1 casserole feeds 5 people
1 : 5 is the ratio.
Divide 30 by 5 = 6
6 casseroles feeds 30 people.
6 : 30
35 divided by 5 = 7
7 casseroles feed 35 people
7 : 35
1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
Answer:
The Choice N#1 will give more pizza for your money
Step-by-step explanation:
step 1
Find the area of one slice Choice #1
The area of the circle is equal to
we have
----> the radius is half the diameter
assume
The area of one slice is equal to
substitute
Divide the cost by the area
step 2
Find the area of the entire personal pizza Choice # 2
The area of the circle is equal to
we have
----> the radius is half the diameter
assume
substitute
Divide the cost by the area
therefore
The Choice N#1 will give more pizza for your money
Answer:
Has not solution.
Step-by-step explanation:
14x÷2 = 6(x - 0)
14x÷2 = 6*x + 6*-0
14x÷2 = 6x - 0
14x = 2*6x
14x ≠ 12x
then:
This equation has not solution.
