Answer:
Step-by-step explanation:
This is a proportion question. You can take either of the other sides besides N to calculate the ratio. You need to use corresponding sides.
Here is the proportion
N/5 = 18/8
Multiply both sides by 5
N = 5 * 18/8
N = 90/8
N = 11.25
Answer:
35
Step-by-step explanation:
7n;n=5
7n
n=5
7×5=
n=35
3x+5y=15
5y=-3x+15
y=-3/5 x +3
It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x
Than subtract 4x on both sides it is now
-20=x
Because 5-4 equals 1 and 1x is just written as x
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
