Caleb - c
Kyras - k
k+c=37
c=2k-4
k+(2k-4)=37
3k=41
k=41/3= ~13.67 years old
c=37-k
c=(111-41)/3
c=70/3=~23.33 years old
Always
a=b
subtract c from each side
a-c = b-c
The answer is D.
To get an area of any 4 sided object (like you text book) , we multiply the length and the width.
All the other answers don't multiply only 2 numbers together, so we know it must be D)

-9x+8(-4)=22
-9x-32=22
-9x=46
x= - 5 1/9

Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.
