From the Pythagorean Theorem, we know that a^2+b^2=c^2
28^2+21^2=(5x)^2
784+441=25x^2
1225=25x^2
49=x^2
x=7
The length of the hypotenuse would be 35m.
X= 2.5
just move the terms collect the terms calculate it, divide both sides !!
Answer: The answer is 8000 pounds, or 4 tons
Step-by-step explanation:
This is true because each tree makes about 250 pounds of oxygen. She counted 32 so.....
(32)(250)=8000
then convert 8000 pounds to tons and you get 4 tons
Step 1:Solve one of the equations for either x = or y = .
Step 2:Substitute the solution from step 1 into the other equation.
Step 3:Solve this new equation.
Step 4:Solve for the second variable.
I hope this helps!
