When writing the equation keep in mind that 7 + x is said as a term that is squared so it has to be squared while it's still together; (7 + x)².
Answer: 80 miles
Step-by-step explanation:
320miles/8hours= 40mph
40mph=xmiles/2hrs
40*2= 80 miles
On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.
on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.
combine like terms on the left to get 7x-6=-2x+2
add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.

Answer:
Case (c) has the lowest unit price and is thus the best buy.
Step-by-step explanation:
Example: (a) The unit price is the price paid divided by the weight:
$0.50
------------ = $0.2857/oz, or (to 2 decimal places) $0.29/oz
1.75 oz
(b) $1.00/(6 ounces) = $0.17/oz
(c) $1.88/(12 ounces) = $0.16/oz
Case (c) has the lowest unit price and is thus the best buy.
