<span>the question is 3 variable equation solution
the three equation will be
5x+4y+7z=152
3x+2y+5z=92
2x+2y+4z=74
solving by elimination we get
x=11,y=12,z=7</span>
Hmm... well, here ya go.
1.50 ÷ 0.05 = 30
So, the total is $30
As for the tax rate, including the total, it would be $31.50.
Hope I helped.
I think it is B. y=0.75x+1. I think that 1 in. of water in a pool is the y-intercept.
A margin of error means how much a prediction can be wrong. So if a prediction is 54% and the margin of error is 4%, then it can be wrong by 4 percent, so it could be 4 % less (50%) or more (58%).
Correct Answer;
X is the actual answer.
50%≤x≥58%
