<span>k= Keisha
k + 6=
John</span>
<span>
k + k + 6
= 4k</span>
<span>
2k + 6 ( - 2k)
= 4k ( - 2k)</span>
<span>
6 = 2k</span>
<span>
3 =
k
(Keisha= 3 years old)</span>
<span>
k + 6 = 9
(John = 9 years old)
</span>
3 + 3 + 6 = 4 (3)

12 = 12
</span><span>So
we made the pawn represent Keisha’s age.
Then we knew that John is 6 years older than Keisha so we represented
his age with a pawn plus 6. This went on 1 side of the equation because it said
that together they equal 4 times Keisha’s age. So on the other side of the
equation we put 4 pawns because we are using each pawn as Keisha’s age. Then we subtracted the pawns from each side
to keep the equation balanced. So we had
that 2 pawns equal 6, which means that each pawn equals 3 so Keisha is 3 years
old. Since John is 6 years older than
Keisha, he must be 9 years old. We
checked our work and substituted 6 in for each pawn and found that 12 equals
12, so our equation is balanced.

Answer:
65 degrees
Step-by-step explanation:
First, solve for the unknown angle( not the y's).
the angle 130 is supplementary to that angle so we will use an equation to solve it. (supplementary means it adds up to 180 degrees)
x+130=180
-130 -130
x = 50 so, 50 is the measure of the interior angle
Now we have to use another equation to solve for y:
50+2y=180
-50 -50
2y = 130
/2 /2
y = 65
Thus, y is 65
Hello from MrBillDoesMath!
Answer:
y = x
Discussion:
x = t^2
y = t^2
I hope you see that
x = t^2 = y
Thank you,

Answer:
16⅜ cups
Step-by-step explanation:
Start by getting the same denominator on both fractions and by eliminating the mixed fraction. So our problem is:
15¾ cups + ⅝ cups = ?
15¾ = 63/4 = 126/8
126/8 + ⅝ = 131/8 = 16⅜
