Its false because it can't repeat in a set.
"the product of" ⇒ ___ * ___
86 ⇒ 86 . . . . . fills first blank
and
the depth of the river ⇒ d . . . . . fills second blank.
Your expression is
86 * d
It's A because 7.5 is the starting point but it's not included so that point is circled.
First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3
Division is like sharing so 85 things that are shared between 5 people
85÷5=17 that is how much each person gets
so 17 is your answer
