The ratio of girls to boys in the sixth grade band is 4: 12. if there are 66 boys, how many girls are there? how many total band members from 6" grade are there?

Step-by-step explanation:

4×3=12

so,

66*3=198

4:12

66:198

198 girls

198+66=264 total

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
