Y = kx
80 = 16k
k = 80/16 = 5

The first 2 choices are corect
Answer: The dimensions are 8 and 3
Step-by-step explanation:
So 8*3=24 which corresponds with the formula for area l*w= Area

Answer: Quotient means when you divided a number by another number.
Our first number will be 48 and also in this problem lets have that second "number" be x.
So 48/x is the quotient.
Given:X: The blue marbles.
3X: The red marbles.
A box contains
144 marbles.
SOLVING:X + 3X = 144
4X = 144
X =

X = 36
===> The blue marbles.If there are
3 times as many red marbles as there are blue marbles:
3(36) = 108
===> The red marbles. SOLUTION
TESTING:

GOOD LUCK...!!!
