HEL PLZZZ IF YOU DOI GIVE YOU BRAINLIEST I DO ANYTHING JUST PLZ HEL PLEASE ANSWER ALL 1. WRITE AN EQUATION For a field trip 4 students rode in cars and the rest filled nine buses. How many students were in each bus if 472 students were on the trip? *

4x=472
9x=472
4+9x=472
4+x=472

2. WRITE AN EQUATIONAliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost? *

24-10=7x
24+7x=10
10+7x=24
10+x=14

1) 4 + 9x = 472

2) 24 - 10 = 7x

Step-by-step explanation:

#1 explanation:

We know that 4 students rode in cars, so we add that. We know there were 9 buses, but we don’t know how many students rode in them so that is our x. All of this is equal to the total number of students, 472. That’s how you get

4 + 9x = 472

#2 explanation:

We know that Aaliyah has $24 total. She had $10 left after buying the pencils, so to find out how much she spent, we subtract them. Now, we know she bought seven pencils, but we don’t know how much they COST so the cost is our x. That’s how you get

24 - 10 = 7x

Hope this helps! :)

Scan be the time on soccer, v can be footballs+v=10, similarly, s=2v+1, so we can sub 2v+1 into the first equation where we see s,(2v+1) +v=103v+1=103v=9v=3, so 3 hours on volleyball. then, we can sub that in to one of our other equations, s+3=10, so s=7.
