In 1 hour, Antoine travels 1.75 mi by dividing 5.25 by 3. So, after lunch, he hiked 4 hours. 1.75 times 2 is 3.5 mi every hour after lunch. So, 3.5 times 4 is 14 mi. + 5.25 is 19.25 mi., or 19 1/4 miles.
Add the two houses together:
135000 + 160000 = 295,000
Multiply the total by the percentage:
295,000 x 0.06 = $17,700
He earned $17,700
First combine like term
(-5x^3+2x^3) + x = 7- 3x^3
After add -5x^3 and +2x^3 together because it has like term is equal -3x^3
-3x^3 + x = 7-3x^3
Plus -3x^3 from both side
Left x alone you get
X= 7
The x is 2 :) I hope it’s right! I’m pretty sure it is though !
