The correct answer for this problem is 700. This is because 0.07 is in the hundredths place. Marco got it wrong because he didn't count the place correctly.
Answer:
x = 2.25 or any number greater
Step-by-step explanation:
5x3 > 4 + 8 + x
Make them equal to each other to get x
5x3 = 4 + 8 + x
(5x)(3) = 12 + x
- x - 3 - 3 - x
4x = 9

x = 2.25
Once you get x plug it in to get the truth of the expression
Set up two equations:
Greg = 330 + 75X
Heather = 660 + 45x
Set them to equal and solve for x:
330 + 75x = 660 + 45x
Subtract 330 from both sides:
75x = 330 + 45x
Subtract 45x from both sides:
30x = 330
Divide both sides by 30:
x = 330 / 30
X = 11
11 months they will have the same amount saved.
Your equation should be 5 - r + 2 = 3.
