Bill tells Matt that he has 3 kids. This means that in this item, we have three unknowns, those are the ages of the three kids. First, the product of the ages is 72.
(x)(y)(z) = 72
Also, for the sum of their ages, we have
x + y + z =?
There are three variables in the equation which means that 3 equations should also be presented to determine the ages of the three children.
The value of 7 in that number is 7 because the 7 is in the ones place
The answer is $15 more per T-shirt
$1.50 because 0.15 x 10 is 1.50
Answer:
There is a total of 45 members in the math club.
Step-by-step explanation:
What I did is I multiplied 9 by 5 and got 45. I multiplied 9 by 5 because the question stated that 9 students are 20%. 20% times 5 would be 100%, which would be the total number of students.
Hope this helped :)
