Answer:

x = 22 (see explanation!)

Step-by-step explanation:

Just with any algebraic equation, you will want to isolate the variable (x). Here's a step-by-step to show you how it's done:

1/7(x + 6) = 4

Multiply by 7 to get rid of the 1/7 (since 7 * 1/7 = 7/7 = 1)

7*1/7(x+6) = 7*4

x+6 = 28

Now, subtract 6 from both sides to isolate x:

x + 6 - 6 = 28 - 6

Finally:

x = 22

A bookcase measures 13 ft wide and 24 ft tall. What would the bookcase's measurements be on a scale drawing using the scale 3 cm
qaws [65]

Answer:

19.5 cm wide

36 cm tall

Step-by-step explanation:

The given, 3 cm : 2 ft, is your first fraction (3 cm / 2 ft). We need to figure out how many cm is 13 ft and 24 ft. Let's start with 13 ft. We would use the first fraction, 3 cm / 2 ft, is equal to x cm / 13 ft. Then, you would cross multiply and get an answer of 19.5 cm. Now, we do the same thing but instead of 13 ft we need to use 24 ft. So again, 3 cm / 2 ft is equal to x cm / 24 ft. Then, cross multiply and get a final answer of 36 cm.

Anestetic [448]

Answer:

The original distance between Dallas and Houston is 240 miles.

Step-by-step explanation:

The scale on a map is 1 cm = 50 miles.

That means, 1 cm length in the drawing is equivalent to 50 miles original distance.

We have to find the actual distance between Dallas and Houston, which are 4.8 cm distant on the map.

So, 4.8 cm length in the drawing will be equivalent to (50 × 4.8) = 240 miles.

Therefore, the original distance between Dallas and Houston is 240 miles. (Answer)
