Answer:

1) x/4 < 4 ⇒ x < 4*4 ⇒ x< 16

x = 4, 8, 12

2) x + 3 ≥ 15 ⇒ x ≥ 12

x = 12

3) 19 > x + 4 ⇒ 15 > x ⇒ x < 15

x = 4, 14

4) 12 ≥ 6x ⇒ 2 ≥ x ⇒ x ≤ 2

x = 1, 2

5) 7x ≤ 21 ⇒ x ≤ 3

x = 1, 2, 3

6) 5 + x < 7 ⇒ x< 2

x = 1

7) x - 5 < 17 ⇒ x < 22

x = 9, 14, 15

8) 3x ≥ 18 ⇒ x ≥ 6

x = 6, 11

9) 20 > x + 9 ⇒ 11 > x ⇒ x < 11

In the diagram, △RST∼△R′S′T′. Determine the length of RS. Show your work.
100 points!

Answers

Answer: 6 feet

Explanation: Since the triangles are similar, we can use the proportion 9/4=(12x+2)/(5x+1).

Cross multiplying 9*(5x+1) and 4*(12x+2) gives us 45x+9=48x+8.

Solving for x gives us 1/3.

You can check your work by plugging in x for the two equations, which gives us 6 (RS) and 8/3 (R’S’)

The scale factor is 4/9 (k) from 9k=4

6*4/9=8/3 and (8/3)/(4/9)=6

Answer:

RS = 6 feet

Step-by-step explanation:

Use ratios of corresponding sides:

TS/T'S' = RS/R'S'

Substitute and solve for x:

9/4 = (12x + 2)/(5x + 1)9(5x + 1) = 4(12x + 2)45x + 9 = 48x + 848x - 45x = 9 - 83x = 1x = 1/3

Find the length of RS:

RS = 12x + 2 = 12(1/3) + 2 = 4 + 2 = 6 feet
