Answer:
The expression [tex]5(3r-10)[/tex] means the product of 5 and the difference of three times r minus 10. If r= 4, the value of the expression is [tex]10[/tex] .
Step-by-step explanation:
The product of 5 and the difference of three times r minus 10 would look like this:
[tex]5(3r-10)[/tex]
If you substitute 4 for [tex]r[/tex], you get
[tex]5[3(4)-10][/tex]
Multiply 3 and 4
[tex]5(12-10)\\[/tex]
Subtract
[tex]5(2)\\[/tex]
Multiply
[tex]10[/tex]
