Introduction to Pre algebre test
Algebra is an important part of mathematics and the pre algebra test is the basic operation is involves in mathematics . Here the topic discuss about the usual terms in algebra like addition, subtraction, multiplication and division. The pre algebre test makes very easy for whom studying the algebra.Let we discuss about the pre algebre test problems. Is this topic Polynomial Factorization hard for you? Watch out for my coming posts.
Pre Algebre Test Problems
Pre algebre test 1:
Determine the value of x in the equation x - 6 = 12
Solution:
Add 6 to both sides of the equation:
x – 6 + 6 = 12 + 6
x = 18
The required solution is x = 18.
Example based on Proof:
6(-3x - 2) - (x -5 ) = -6 (3x + 5) + 13
Multiply the factors-18x - 12 - x + 5 = -18x - 20 +13
Group like terms
-18x - 7 = -18x - 7
Add 18x + 7 to both sides 0 = 0
Hence the prooved.
pre algebre test 2 :
Determine: 6(c – 2) + 5 = 8
Solution:
Step 1: Remove the brackets
6c – 12 + 5 = 8
Step 2: Isolate variable a
6c = 12 – 5 + 7
6c = 14
c=16/14 = 3.4
Answer: c = 1.42
pre algebre test 3:
Addition and subtraction
1) Solve: x + 62 = 262
Solution:
x + 62 = 262
subtract 62 on both sides
x + 62 - 62 = 62 -262
x = 200
pre algebre test 4:
Solve: y - 82 = 756
Solution:
y - 82 = 756
(Add 82 on both sides)
y - 82 + 82 = 756 + 82
y = 838.
I have recently faced lot of problem while learning Simplifying Rational Expressions, But thank to online resources of math which helped me to learn myself easily on net.
More Problems in Pre Algebre Test
Pre algebre test 1:
Multiplication and division
Solve: 7y = 49
Solution:
7y = 49
Divide by 7 on both sides
(7y) / 7 = 49 / 7
xy= 7
pre algebre test 2:
Solve: y / 8 = 64
Solution:
y / 8 = 64
multiply by 8 on both sides
8(y / 8) = 64(8)
y = 512
pre algebre test 3:
Combination of operations
1) Find: 6y - 6 = 36
Solution:
6y - 6 = 36
6y - 6 + 6 = 36 + 6
6y = 42
(6y) / 6 = 42 / 6
y = 7
Pre algebra test 4:
Solve: 4(y + 8) = 32
Solution:
4(y + 8) = 32
[4(y+ 8]/4 = 32/8
y + 8 = 4
y + 8 - 8 = 4- 4
y = 0
Practice Problems in Pre Algebre Test
1) Solve: x + 72 = 64
Answer: x = 8
2)Solve: y - 16 = 99
Answer: y = 115
3)Solve: y / 9 = 82
Answer: y = 738
4) Find: 2y - 2 = 4
Answer: y = 3
