What are the coefficients of the variables in the expression 5 + 8y - 6 + 4r? a
5, 4
b
8, 1
c
6, 5
d
4, 8
Please help me out!

The terms that have variables are 8y and 4r

The coefficients are the numbers to the left of the variables, so the coefficients are 8 and 4.

The terms 5 and -6 are constants that don't have any variables attached to them (so those terms do not change; whereas the terms with variables do change depending on what the variable is equal to).

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
