There are 54 students on a school bus. The number of high school students is 3 more than twice the number of middle school students.
How many of high schoolers are on the bus? State your answer in a
sentence.

there are 37 high school students on the bus

Step-by-step explanation:

h+m=54   total number of students

h= 2m+3 total number of HS students

2m+3+m=54    Substitute 2m+3 in for h

3m+3=54

3m=51

m=17

h+17=54

h= 37

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
