### Answers

**Answer:**

x=3/16

**Step-by-step explanation:**

**Answer:**

3/16

**Step-by-step explanation:**

32(4x−1)−3x=54−(x+2)

32(4x−1)−3x=54+−1(x+2)(Distribute the Negative Sign)

32(4x−1)−3x=54+−1x+(−1)(2)

32(4x−1)−3x=54+−x+−2

(32)(4x)+(32)(−1)+−3x=54+−x+−2(Distribute)

6x+−32+−3x=54+−x+−2

(6x+−3x)+(−32)=(−x)+(54+−2)(Combine Like Terms)

3x+−32=−x+−34

3x+−32=−x+−34

Step 2: Add x to both sides.

3x+−32+x=−x+−34+x

4x+−32=−34

Step 3: Add 3/2 to both sides.

4x+−32+32=−34+32

4x=34

Step 4: Divide both sides by 4.

4x4=344

Suppose y varies with x. Write a direct variation equation that relates x and y. Then find the value of y when x=10

### Answers

**Answer:**

y = 1.5xy = 15 when x = 10

**Step-by-step explanation:**

A direct variation equation is of the form ...

y = kx

for some constant k. We can arbitrarily choose k=1.5, so our equation is ...

** y = 1.5x**

For x=10, the value of y is ...

** y = 1.5·10 = 15**

**Step-by-step explanation:**

An object is moving at a speed of 9 kilometers every 6.5 years. Express this speed in inches per day. Round your answer to the nearest whole number.

### Answers

**Answer:**

**The object is moving at 149 inches per day.**

**Step-by-step explanation:**

The speed can be converted from km/y to in/d taking into account that:

In 1 kilometer we have 39370.1 inches and in 1 year we have 365 days, hence:

[tex] V = \frac{9 km}{6.5 y}*\frac{39370.1 in}{1 km}*\frac{1 y}{365 d} = 149 in/d [/tex]

**Therefore, the object is moving at 149 inches per day.**

Determine the slope of each line:

### Answers

**Answer:**

a=(2/5), b = (-2,6)

Step-by-step explanation:

Karen has 2/3 of her juice box left. Her brother drinks 3/4 of that. How much of the juice box does her brother drink?

### Answers

**Answer:**

1/2 of the juice box

**Step-by-step explanation:**

We see that Karen has 2/3 of her juice box left. Her brother drinks 3/4 of that leftover 2/3.

First, remember that "of" in mathematics usually means to multiply. Here, since the brother drank 3/4 **of** the 2/3, we multiply the two:

(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6 / 12 = 1/2

We understand this as 1/2 of the entire thing.

So, Karen's brother drank **1/2 of the juice box**.
