80+ 80= 160 miles
160 miles/ 7 hours= 22.857 miles per hour
Seems like you’re gonna fail
Use the Product Rule: x^ax^b = x^a + b
3x^-4 + 1 - 5 - 3(5x^-2x + 1)
Simplify -4 + 1 to -3
3x^-3 - 5 - 3(5x^-2x + 1)
Use the Product Rule: x^a x^b = x^a + b
3x^-3 - 5 - 3(5x^-2 + 1 + 1)
Simplify -2 + 1 to -1
<u>3x^-3 - 5 - 3(5x^-1 + 1)</u>
The answer will be 1.80
I divided 2.99 by 5 to find the price of each lb which is 0.6 and then multiplied by 3 which equals to 1.80
