a. 105
b. 120
c. 180
d. 195

Answers

1. D
5x+ 3 = 7x-1
now collect like terms
3+1 = 7x-5x
every time you move something it changes signs
4= 2x anything multiplied is divided on the other side and vice versa
4/2 =x
2 = x

2. C
5x + 2(x + 7) = 14x – 7
5x + 2x + 14 = 14x – 7
7x + 14 = 14x – 7
7x + 14x = -14 – 7
-7x = -21
x = 3

3. A

4. C
5(z+1) = 3(z+2) + 11. Z=?
5z + 5 = 3z + 6 + 11
5z + 5 = 3z + 17
5z = 3Z + 17 – 5
5z – 3z = 12
2z = 12
z = 6

5. D

6. C

7. D
The first time, Brian answered 150 questions correctly and the second time he answered 30% more correctly, so,
150 + (30/100 * 150) ;  30% of 150 = 45, or (30 * 150)/100
so 150 + 45 = 195

  1. I need to know how to do the formula in order to pass algebra to get accepted into a practical nursing program. Also, I need to learn basic mathematics.

    1. In order to solve it you have to look at the two sides separated by the equal sign then combine like terms after you add or subtract from both sides so a variable(s) is on one side and the numbers are on one side then if they have a common factor divide them by the smallest of the two then you will get your answer.
