Jayden drew a scale drawing of an arcade. He used the scale 1 inch = 3 feet. If an air hockey table is 3 inches long in the drawing, how long is the actual air hockey table?

9 Feet

Step-by-step explanation:

Lets start with a ratio:

1:3

Now lets look at the other ratio:

3:?

If the 1 turned into a three in the second ratio, then what will the 3 in the first ratio turn into?

9!

Because 1x=3 should be equivalent to 3x=9

Lets check our work:

x=3

3x=9

Simplify by dividing by 3 on both sides:

x=3

x=3

It worked!

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
