Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6
Answer:
1. 80%
2. ?
3. $28.37
4. 37.5
5. around 6.1
6. 15
7. 333
8. $228.56
9. 0.24%
10. around 24.6% so if you round it , it would be 25%
11. 83.3%
12. $86.20
(7)^2 +
2nd power means squaring a number and since you need to do that first, it goes in brackets.
