PLEASE HELP ASAP!!

Mathematics
1 answer:
NNADVOKAT [17]3 years ago

Answer (the system of equations input doesn't work, so there is no brace):

x = 1.5y

x + y =800

Step-by-step explanation:

First, identify the vital information:

- 800 total students

- 1.5 times as many boys as girls

So, if x = number of boys and y = number of girls, we can agree that:

x = 1.5y

And because there are 800 kids in total, we can agree that:

x + y = 800

There are 320 girls and 480 boys. (see below)

Since you have the value of x, 1.5y, you can plug-in the value:

x + y = 800

1.5 + y = 800

2.5y = 800

y = 320 girls

Plug-in the y-value into the equation for the number of boys:

x = 1.5y

x = 1.5(320)

x = 480 boys

To double-check:

320 + 480 = 800 ☺
