Answer:

C. Apply the distributive property to get 4x-12=9.

Step-by-step explanation:

To get x out of the parentheses, you have to use the distributive property by multiplying both x and -3.

Hope this helps you :)

Given triangle PRS is congruent to triangle CFH, find the values of x, y, and z.
Mashutka [201]

Answer:

x = 23

y = 7

z = 11

Step-by-step explanation:

Since ∆PRS ≅ ∆CFH, therefore,

m<R = m<F

13y - 1 = 90° (substitution)

Add 1 to both sides

13y - 1 + 1 = 90 + 1

13y = 91

Divide both sides by 13

13y/13 = 91/13

y = 7

Since ∆PRS ≅ ∆CFH, therefore,

PS = CH

2x - 7 = 39 (substitution)

Add 7 to both sides

2x - 7 + 7 = 39 + 7

2x = 46

Divide both sides by 2

2x/2 = 46/2

x = 23

Since ∆PRS ≅ ∆CFH, therefore,

m<S = m<H

Find m<S

m<S = 180 - (m<P + m<R) (sum of ∆)

m<S = 180 - (28 + (13y - 1)) (substitution)

Plug in the value of y

m<S = 180 - (28 + (13)(7) - 1))

m<S = 180 - (28 + 91 - 1)

m<S = 180 - 118

m<S = 62°

Therefore, since m<S = m<H,

62° = 6z - 4 (substitution)

Add 4 to both sides

62 + 4 = 6z - 4 + 4

66 = 6z

Divide both sides by 6

66/6 = 6z/6

11 = z

Dory lives 2.5 miles from school. Jim lives 3.2 kilometers from school. Ely lives 2300 meters from school, and Chris lives 3000
dezoksy [38]

Answer: Ely, Chris, Jim, Dory

Step-by-step explanation:

The distances must be expressed in the same uni.

Let's express the distance in meters.

We know that Dory lives 2.5 miles from school.

Since:

1\ mi = 1.61\ km

The distance  in kilometers is:

(2.5\ mi)(\frac{1.61\ km}{1\ mi})=4.025\ km

Since 1\ km = 1,000\ m

The distance in meters is:

(4.025\ km)(\frac{1,000\ m}{1\ km})=4,025\ m

 Jim lives 3.2 kilometers from school. The distance in meters is:

(3.2\ km)(\frac{1,000\ m}{1\ km})=3,200\ m

Chris lives 3,000 yards from school.

Since:

1\ m = 1.09\ yd

The distance in meters is:

(3,000\ yd)(\frac{1\ m}{1.09\ yd})=2,752.29\ m

Therefore, the order of the students from closest to farthest from school is:

Ely, Chris, Jim, Dory
