In a scale model of a television, 1 centimeter represents 9 inches. Scale
1 cm 9 in
Answer the following.
x
?
(a) In the scale model, the height of the television is 5
centimeters. What is the height of the real television?
inches
(b) The length of the real television is 81 inches. What is the
length of the television in the scale model?
centimeters

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
