Kind of lengthy but hope it helps! ;)
Part A
From the two buildings she rents, the building costing $643, 225 price is greater than the other that costs <span>$635, 895
Part B
Round to the nearest ten thousand:
</span><span>$635, 895 ~ $640, 000
this is because 5,895 rounds to 6,000, and then this rounds to 10,000
</span><span>$643, 225 ~ $640, 000
</span>this is because <span>43, 225 rounds to 40,000 the nearest ten thousand</span>
For X the answer would be..

Now for Y the answer would be..

Answer:
x=27
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5/3x-4/3x-1=8
5
/3
x+ −4
/3
x+−1=8
(5
/3
x+ −4
/3
x)+ (−1) =8 (Combine Like Terms)
1/3x-1 =8
1/3x=9
(1/3 x) x 3 = 3 x 9
x=27
