So what you want to do for all of these is move the variable that you want to be the subject to one side of the equation and the other ones to the other side, then divide.
For example:
With number 1, m = 3n + 2p, since you want to make p the subject, first single out p by subtracting 3n from both sides.
m - 3n= 3n + 2p - 3n
2p = m - 3n
Then divide everything by 2.
2p / 2 = m/2 - 3n/2
p = , you could also say 1/2m - 3/2n
p = 1/2m - 3/2n
Next question: just do the same thing.
a = 3c - 4
a + 4 = 3c - 4 + 4
3c = a + 4
/3 /3 /3
c = 1/3a + 4/3
Next question: same process.
P - 2a = 2a - 2a + 2b
2b = P - 2a
/2 /2 /2
b = 1/2P - a

<h2><u><em>Answer: meters.
</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>Step-by-step explanation: Let L be the length of the rectangle. We have been given that the rectangle has an area of square meters and a width of meters. Since we know that area of a rectangle is the product of its length and width. To find the length of our given rectangle we will divide the area of the rectangle by the width of our rectangle. Let us factor out our numerator by splitting the middle term. Upon canceling out x-7 from numerator and denominator we will get, Therefore, the length of our rectangle will be metered.</em></u></h2>
Answer:
7a +19.5 = 112.25
Step-by-step explanation:
A suitable equation is ...
weight of alternators + weight of wheel = total weight
Since one alternator weighs "a", seven of them weigh 7a. Filling in the given values, this equation is ...
7a + 19.5 = 112.25 . . . . . matches choice D
