Please help me answer this

Train was late by 13 minutes.

Step-by-step explanation:

Time train took to travel = 290 miles / 50 mph

= 5.8 h

= 5h 48 min.

Time train left = 10:10 am

Time of arrival

= 10:10 + 5:48

= 15:58 pm

= 3:58 pm

Scheduled time of arrival

= 3:45 pm

Train arrived late by

3:58 - 3:45

= 0:13

= 13 minutes.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
