The ratio of red balloons to blue balloons at a party is 4 to 9. If there are 20 red balloons, how many blue balloons are there?

Step-by-step explanation:

4/9 to 20/x

cross multiply and divide to get your answer

4     20

9     x

4x=180

x=45

answer: i wpould go with c

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
