Keith and michelle went out to dinner. the total cost of the meal, including the tip, came to $53.70. if the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?

$22.05

Step-by-step explanation:

you just need to subtract the tip from the total and then divide by 2 so

$53.70-$9.60= 44.10

44.10 ÷ 2= 22.05

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
