Answer:
The total weight change for the eight women was -24.
Step-by-step explanation:
In order to find the answer, you have to consider that average is calculated by dividing the total weight change by the number of women and you know that the average was they lost 3 pounds and there were 8 women:
Average= total weight change/number of women
-3=total weight change/8
total weight change=-3*8
total weight change=-24
According to this, the answer is that the total weight change for the eight women was -24.
So 22 problems/ 30 minutes = ? problems/ 180 minutes
so you basically just convert them
and you will times 30 by 6 to get 180, so you times 22 by 6
and you will get 132 problems
so Koby can do 132 problems
Y=6x, 2x+3y=-20
Substitution means just plugging in another equation equal to a single variable in order to solve for the other variable, and then the first. In this case, the equation being plugged in is y=6x, so 6x will be put in place of y in the equation 2x+3y=-20.
2x+3(6x)=-20
2x+18x=-20
20x=-20
x=-1
And then x=-1 can be plugged into the original equation to find y. (And, if you wish, into the y= equation to check it.)
2(-1)+3y=-20
-2+3y=-20
3y=-20+2
3y=-18
y=-6
And to check it, we plug the two into the original y= equation.
y=6x
-6=6(-1)
-6=-6
They are equal, so both check out.
x=-1, y=-6
