Answer:
you just substitute the variable for its values
like based on the above
m change into 7
r change into 8
t change into 2
then, solve
Step-by-step explanation:
5(7)-6
35-6
29
8/2
4
(7)(2)
14
4(7)+2
28+2
30
3(7)-5(2)
21-10

EVALUATING ALGEBRAIC EXPRESSIONS
[tex]__________________________[/tex]
Given:
Answer & Solution:
To evaluate algebraic expressions just substitute the values of the variables to the expression then solve it usung the orders of operation.
[tex]\sf 6.) \: 5m - 6[/tex]
[tex]\sf = 5(7) - 6[/tex]
[tex]\sf = 35 - 6[/tex]
[tex]\sf = \boxed {\sf 29}[/tex]
[tex]\sf 7.) \: \frac{r}{t} [/tex]
[tex]\sf = \frac{8}{2} [/tex]
[tex]\sf = \boxed{ \sf 4}[/tex]
[tex]\sf 8.) \: mt[/tex]
[tex]\sf = (7)(2)[/tex]
[tex]\sf = \boxed{ \sf 14}[/tex]
[tex]\sf 9.) \: 4m + t[/tex]
[tex]\sf = 4(7) + (2)[/tex]
[tex]\sf = 28 + 2[/tex]
[tex]\sf = \boxed{ \sf 30}[/tex]
[tex]\sf 10.) \: 3m - 5t[/tex]
[tex]\sf = 3(7) - 5(2)[/tex]
[tex]\sf = 21 - 10[/tex]
[tex]\sf = \boxed {\sf 11}[/tex]
