<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441

Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
C. 48 is the answer for 3(2x^2-£)
Since there is an addition symbol in the middle all you need to do is combine like terms/add. Your final answer should be:
p= 5s+5
