lidiya [134]

The number of adults waiting to see the new superhero movie is 62.

<h3>How many adults are waiting in line?</h3>

Ratio expresses the relationship between two or more numbers. Ratio is used to compare two or more numbers. It shows the number of times that one value is contained in another value.

Looking at the ratio given in this question, we know that there are 1 1/2 (3 /2) more children than adults on the line to watch the new superhero movie.

Number of adults waiting to see the movie = (ratio that represents adults / sum of ratio) x total number of people wafting in line

Sum of ratios = 2 + 3 = 5

(2/5) x 155 = 62 people

Elimination method. -2y = 0.5 - 2x<br> 6х + Зу = 6
AysviL [449]

Answer:

y=-1.5

X=1.75

Step-by-step explanation:

Yuh arrange the equations in order for easy subtracting of the equations.

-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.

6x+3y=6

3y=-6x+6 then divide both sides by three to get y

y=-2x+2

now arrange

y=-2x+2

y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x
