X = 28% * 80
x = 28/100 * 80
x = 28/10 * 8
x = 2.8 * 8
x = 22.4
28% of 80 is 22.4.
Your final name is a. 22.4
<span>P= IRT solve for T
To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side.
IRT means that I and R are multiplied by T.
To get rid of them we must do the opposite of multiply, which is divide.
But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side.
So if we divide the right side by IR, we must also divide the left side by IR</span>

By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
<h3>How to find a constant of proportionality in direct proportional equation</h3>
Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of <em>direct</em> proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:
k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week
By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
