40/2=20 half is as many their is if she has lest of seven round to the highest num because they are all even numbers
Answer:
0.08
Step-by-step explanation:
Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

Hi,
850 $ -- 6%*850 $ = 850 $ -- 6*850/100 $ = 850 $ -- 5100/100 $ = 850 $ -- 51 $ = 799 $.
Easy, huh ?
