A high school graduating class is made up of 351 students. There a 73 more girls than boys. How many boys are in the class

139 boys

Step-by-step explanation:

Using the given information, we can set up a system of equations.

Let the number of girls in the class be x and let the number of boys in the class be y.

x + y = 351

x = y + 73

Solving this system of equations would tell you that there are 139 boys in this graduating class.

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!
