It’s number 6a i don’t get how we do this

There are 8 girls on the team.

Step-by-step explanation:

In this equation, we are being asked to find how many girls are on a 20 person team that has 12 boys.

We will use the variable g to represent girls.

We know that the sum of all the boys and girls on the team is 20, and that there are 12 boys, so lets write the equation out.

12 boys + g girls = 20 members

12 + g = 20

(12 + g) = (20)

(12 + g) - 12 = (20) - 12

g = 8

girls = 8

There are 8 girls on the team!

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

found it xd it ok yt
