Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
Answer:
The answer is $97.35
Step-by-step explanation:
This because you would need to multiply 75x1.298 to get your answer and your conversion method is multiplying so your answer is $97.35
Hope this helps and have a great day!!
This is the concept of algebra, to get the slope of the line we need to rewrite the equation in slope intercept form y=mx+c, where m=slope, c=y-intercept.
Therefore re-writing our expression in slope-intercept form we get:
7x-3y=10
-3y=-7x+10
y=7/3x-10/3
The slope=7/3
hence we conclude that the slope of the line perpendicular to this is -3/7
Answer:
x = -20
