PERT Test Maths Review Questions and
Answers
an equation between two or more variables that gives a straight line on a graph -
ANSWER-linear equation
2x + 3 = -15
-3 + 2x + 3 = -15 - 3
2x = -18
1/2 • 2x = -18 • 1/2
x = -18/2 = -9 - ANSWER-2x + 3 = -15
5x - 3 - 7x = x + 8
-2x - 3 = x + 8
-x + (-2)x - 3 = x + 8 - x
3x - 3 = 8
3 + (-3)x - 3 = 8 + 3
-3x = 11
-1/3 • (-3)x = 11 • (-1/3)
x = -11/3 = -3 2/3 - ANSWER-5x - 3 - 7x = x + 8
3/x = 5
x • 3/x = 5 • x
3 = 5x
1/5 • 3 = 5x • 1/5
x = 3/5 - ANSWER-3/x = 5
.15 = p/40 × 100
0.15 • 40 = 6.00
6 - ANSWER-15% of 40
0.2 ---> 0.002
0.002 • 7 = 0.014
.014 - ANSWER-.2% of 7
.2x = 4
