Answer:

1. D

2. A

3. C

Step-by-step explanation:

1. Given

6-\dfrac{1}{2}z=\dfrac{2}{3}

Multiply the equation by 6:

6\cdot 6-6\cdot \dfrac{1}{2}z=6\cdot\dfrac{2}{3}\\ \\36-3z=4

Hence,

-3z=4-36\\ \\-3z=-32\\ \\3z=32\\ \\x=\dfrac{32}{3}

2. Given

\dfrac{3y}{2}+\dfrac{ky}{4}=6

Multiply the equation by 4:

\dfrac{3y}{2}\cdot 4+\dfrac{ky}{4}\cdot 4=6\cdot 4\\ \\6y+ky=24

Use distributive property:

y(6+k)=24\\ \\y=\dfrac{24}{6+k}

3. Given

3-(w+2)>4+2w

Open the brackets using distributive property:

3-w-2>4+2w\\ \\1-w>4+2w

Hence,

1-w>4+2w

How fast is the train going if it can travel<br> 100 miles in 30 minutes?
DerKrebs [107]

30 min = 30/60 hr = 0.5 hr

d = rt

100 = r*0.5

100/0.5 = r

200 = r

r = 200 mph.

We know that Rate = distance/time

(30 minutes is .5 hour)

Rate=100 mile/.5 hour

Divide and we get:

Rate=200 MPH

(Hint: MPH is Miles per Hour---Per means "for each")

Make sense?

Solve 10/12 - 3/8 show your solution as an equation​
elena55 [62]

Answer:

11/24

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. The two fractions now have like denominators so you can subtract the numerators.

This fraction cannot be reduced.

Therefore the answer is 11/24
