Two submarines were headed toward one another. One followed the path represented by the equation y = 4x + 7. The other submarine followed the path represented by the equation y = 3x + 12. Let x represent the number of minutes the submarines have been in motion and y represent the distance each is from the submarine base. a. Solve the system of equations using two input-output tables to determine when the submarines' paths will cross.

b. Explain how you know your answer is correct.​

to have more of what you want like money

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
