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.
Answer:
Step-by-step explanation:
∵∛x = (x)^1/3
∴
So you can replace the radicals by fractional exponents
Because the shadow doubled, the tree is actually only 11 FEET TALL.
300
because 3 x 1 = 3 +00 = 300... make sense?
The answer is none of the lines intersect each other, because they are at the same slope, and they do not have a different slope for the lines to be intersected.
