-9/4v + 4/5 = 7/8;
First, you subtract 4/5 from each side to have variable v on a side and numbers on the other:
-9/4v = 7/8 - 4/5;
-9/4v = 35/40 - 32/40;
-9/4v = 3/40;
Then you divide each side to get the variable v alone on a side, and one number on the other:
V= (3/40) / (-9/4);
Dividing to fractions is equal to multiplying the first one by the inverse of the second:
V= (3/40) * (-4/9);
V= -12/360;
V= -1/30;
You can re-check your answer (very important):
(-9/4)*(-1/30)+4/5=7/8;
The answer has been approved.
Hope this helps! :)
Answer:
The equation of the perpendicular line would be y = -2/5x - 1
Step-by-step explanation:
In order to find this line, we must first find the slope of the original line. We do this by solving for y.
-5x + 2y = -10
2y = 5x - 10
y = 5/2x - 5
This shows us a slope of 5/2. TO find the perpendicular slope, we use the opposite and reciprocal. This means we negative 5/2 to get -5/2 and then we flip it to get -2/5. Now that we have this, we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = -2/5(x + 5)
y - 1 = -2/5x - 2
y = -2/5x - 1

Sorry, this may be wrong. I am using an old skill, so it may be wrong.
Let P = number of problems solved per day.
P = 448/28
P = 16
