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.
Answer:
128 > 4*(x + 7)
Step-by-step explanation:
Given the following data;
Length = 4 meters
Width = x + 7 meters
Area = 128 m²
Mathematically, the area of a rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
128 > 4*(x + 7)
128 > 4x + 28
128 - 28 > 4x
100 > 4x
Dividing both sides by 4, we have;
25 > x
You add the external lengths together
12x2=24
The middle is extra. All you need to answer is the $12 is half his allowence left.
