Answer:
k is the constant of proportionality
2 1/4 gallons
Step-by-step explanation:
y = kx, k is the constant of proportionality
y = how much of the tank is filled
x = how many gallons used
1/3 = k (3/4)
Multiply each side by 4/3 to isolate k
4/3*1/3 = k (3/4)*4/3
4/9 = k
y = 4/9x
We want y to be 1 for a full tank
1 = 4/9 x
Multiply each side by 9/4 to isolate x
9/4 = 4/9 x * 9/4
9/4 =x
We need 9/4 gallons or simplifying
2 1/4 gallons
Hi so we are going to select the story problem that this division problem represents so let’s get to it!
The answer is going to have to be 2 and 1/4 or 2.25 and the word problem is going to be Lauren jogs around a rectangular course with a length of 3/4 mile and an area of 1/3 square mile. How wide is the course?
Answer:
A
Step-by-step explanation:
2.1 Factoring 4x2+12x+9 The first term is, 4x2 its coefficient is 4 . The middle term is, +12x its coefficient is 12 . The last term, "the constant", is +9 Step-1 : Multiply the coefficient of the first term by the constant 4 • 9 = 36 Step-2 : Find two factors of 36 whose sum equals the coefficient of the middle term, which is 12 .
I would but I’m like really bad at math so
I think the answer is 1.5?
