Answer:
10
Step-by-step explanation:
5 · (3r - 10)
If r = 4, this expression becomes 5 · (3[4] - 10), or 60 - 50, or 10.
Answer:
the value of the expression is 10
Step-by-step explanation:
The expression means the product of 5 and the difference of three times r minus 10.
'r' represents the variable
three times 'r' is 3r
for minus 10, subtract 10 from 3r
[tex]3r-10[/tex]
the product of 5 and the difference of three times r minus 10.
[tex]5(3r-10)[/tex]
Now evaluate the expression when r=4
Plug in 4 for 'r' in the expression we got
[tex]5(3r-10)[/tex]
[tex]5(3(4)-10)[/tex]
[tex]5(2)[/tex]
10
