Answer: JK+KL=JL <--> 4x+6+7x+15=120 <--> x=9
JK=4x+6=4.9+6=42
KL=7x+15=7.9+15=78
1. 9^7

3. 10^8
4. 3^9
5. 2^12
Answer:
Step-by-step explanation:
In algebra we work with variables and numerals. To evaluate an algebraic expression simply means that you are going to determine the value of an expression by substituting and evaluating using the operation order.
in summary in order to evaluate an algebraic expression
- you must identify the variable and its value
- you will substitute the given value for the variable
- complete the necessary calculations
Take for example;
evaluate 2a + 4b - 2c
given that a = 2 , b = 1 , c = 5
since you already know the value of the variables you substitute them into the question
we have
2(2) + 4(1) +2 ( 5)
4 + 4 + 10
