Answer: 5:6

Explanation: We have 55 balloons. So, that means we must figure out a common factor between 25 and 30. That means the only factor is 5. So, that means after each 5 blue balloons there will be there will be 5 green balloons.

What is the area? 20 in 25 in square inches

slava [35]

Answer:

250 in sq

Step-by-step explanation:

Here's the solution

=> Base = 25in

=> Height = 20in

=>We need to find out area of traingle

=> Area of traingle = 1/2*base *height

=> Area = 1/2*20*25

=> Area= 250 in sq

hope it helps. ^_^

Which of the following ordered pairs represents a solution to the linear inequality y>2x-3

expeople1 [14]

Answer:

The solution of the inequality in the attached figure

Step-by-step explanation:

we have

$y> 2x-3$

we know that

The slope of the dashed line is positive $m=2$

The equation of the dashed line is $y=2x-3$

The y-intercept of the dashed line is the point $(0,-3)$

The x-intercept of the dashed line is the point $(1.5,0)$

Graph the inequality

The solution of the inequality is the shaded area above the dashed line

see the attached figure

Remember that

If a ordered pair is a solution of the inequality

then

the ordered pair belong to the shaded area and the ordered pair must satisfy the inequality
