First set up the equation:
number * percent = part
So your answer is
140.
For the two lines to be equal, they have to have the same slope.
So put the other one in slope intercept form because the first one is already in the equation of y=mx+b, where m is the slope.
5y+2x=4
5y=-2x+4
y=-2/5x+4/5
The second line has a slope of -2/5
The first line has a slope of 2.
They are not parallel, because they don't have the same slope. One has a slope of -2/5 and the other one has a slope of 2.

Answer:
(a) it is less then
(b) it is greater then
Step-by-step explanation:
it those because that the right answer
-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
Two ways of solving this, you can just expand and solve, or combine like terms then solve. I will combine like terms.
<span>-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
</span>(2*-1.5)(4-n) + (2*2.8)
-3(4-n) + 5.6
-3*4 + 3n + 5.6
-12 + 3n + 5.6
3n - 6.4
