Recall that a square is just a rectangle with all sides equal.
and the area of a rectangle is just length * width.
The equation for the first option is Y=10x + 200
The equation for the second option is Y=30x + 100
X = one month
To find when they would be the same about you have to set the equations equal to each other
10x + 200 = 30x + 100
-10x -100 -10x -100
100= 20x
5 = x
After five months she would save the same amount. To find how much is saved you have to plug in 5 for x in one of the equations. You can always double-check 5 by plugging it in both equations and making sure you get the same answer
Y= 10(5) + 200 = 250
Y= 30(5) + 100 = 250
She would have saved $250 after five months by using either method
Answer:
43%
Step-by-step explanation:
Last month, 72.
This month, 126.
Last month, ebony had 72/126 in her account to what she has this month. 72/126 as a percentage.
Ratio:
72:126
X100
7,200:12,600
÷126
57.142:100
Ebony had approximately 57% of her cash in her account last month, compared to this month.
Answer:
divide the least common denominator by the original denominator
