Answer:
(u – t)(u² - 12) is equal to 0.5.
Step-by-step explanation:
First let's find u and t:
Given u + t = 5, and u - t = 2
We'll substitute one of those into the other equation.
Let's solve the second one for u:
u - t = 2
u = 2 + t
Now we can substitute that definition into the first equation:
u + t = 5
(2 + t) + t = 5
2 + 2t = 5
2t = 3
t = 1.5
Now we can substitute that into either of the original equations to find u:
u = 2 + t
u = 2 + 1.5
u = 3.5
So t = 1.5 and u = 3.5. Now we can substitute them into the given expression to solve it:
(u – t)(u² - 12)
= (3.5 – 1.5)(3.5² - 12)
= (3.5 – 1.5)(12.25 - 12)
= 2 × 0.25
= 0.5

Answer:
$0.5
Step-by-step explanation:
formula ; y = kx
where ; y = $1.5
x = 3 pounds of bananas
k = constant of proportionality
Step 1. Do the equation based on the data given
y = kx
$1.5 = k3
Step 2. Compute the mathematical equation. Divide both sides by the coefficient of 3.
<u>$1.5</u> = <u>k3</u>
3 3
k = .5
Answer; $0.5 is the constant of proportionality cost in dollars per pound of banana.
