How to Evaluate Equations?
To evaluate an equation, place the value of the given variable into the expression given.
1. 14 - a² is given, if a = -3, therefore, the expression would be evaluated as:
= 14 - 3²
= 14 - 9
= 5
2. "fifteen" = 15
"sixty-one" = 61
Therefore, "fifteen more than r is 61 is represented by the equation:
B. r + 15 = 61
3. Evaluate 4² - 2(3 × 5 + 1)
16 - 2(15 + 1)
16 - 2(16)
16 - 32 = -16
The value is: C. -16
4. |-3| = 3
Therefore, |-3| is greater than -2. That is, -2 is less than |-3|. The symbol needed would be: A. <.
5. Evaluate 7(10 - 2³) + 8 ÷ 2:
7(10 - 8) + 4
7(2) + 4
14 + 4
= 18.
The answer is: C. 18
6. From the least to the greatest, the set of integers that are in the right order is: D. -3, 2, 7, |-10|
7. (-42) + (42) = 0. Therefore, the additive inverse of -42 is: B. 42.
8. 107 -(-25)
107 + 25
= 132
The answer is: A. 132
