Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:
2.25/ 1.5 = x/1
2.25 is the 2 1/4 converted which is the amount of hours she took.
1.5 is the 1 1/2 converted which are the amount of pages she wrote total.
1 on the right side of the proportion represents 1 page.
And x are the amount of hours used to write 1 page.
And in solving that proportion it would result in 1.5 or 1hr. and 30 min.
This is what you need i think
Yes the equations are equivalent
Inequalities and equations use similar steps to solve, but inequalities give a range of numbers that can represent the variable while an equation will give a direct answer.
Example:
4+5x=24
First you would subtract 4 or add the opposite of 4 from 24.
4+5x=24
+(-4) +(-4)
—————
5x=20
Then divide each side by 5 or multiply each side by the reciprocal of 5 to isolate the variable.
1/5*5x=20*1/5 (reciprocal)
X= 4
You would use the same steps in an inequality but end up with a different sign.
