### What is the answer to the mathematical equation m=t-r for r?

What one does to one side of the equation must be done to the other.
Starting with m=t-r, add r to both sides:
m+r = t-r+r or m+r=t. Subtract m from both sides:
m+r-m=t-m or m-m+r= t-m or r=t-m

### Is algedra the only tip of math that an electrician needes to now?

In general no. He/she will need some elementary vector calculus as well if he will try solve problems regarding design of various circuits powered by AC. Some elementary integral/differential calculus will be useful if he/she wants to solve more complicated problems with respect to power/energy consumption for example.Let just say Algebra is a MUST!

### 6+22)/ 2-12 x 3

Just follow the order of operations. 1. Parenthesis 2. Exponents 3. Multiply and Divide in order from left to right, and 4. Add and subtract in order from left to right. I'm assuming you are missing the left parenthesis before the 6 (.

(6 + 22) / 2 -12 x 3 =
28 / 2 - 12 x 3 =
14 - 36 =
-22

### Math Word Problem

First, you need to get the probability of the two events - not enough rain and enough rain.
The probability of not enough rain is 1 less the probability of enough rain.

Supposing that the probability of not enough rain is 0.70, then the probability of enough rain is 0.30.

Therefore to get the profit per acre, you multiply these probabilities with their profits per acre. Hence,
\$4000 * 0.30 + \$1600 * 0.70 = \$2,320 is the average profit per acre.

The above method uses the mathematics principle of the weighted expected returns.

I hope this helps.
