17 = -13 -8x

Add 13 to both sides:

30 = -8x

Divide both sides by -8:

x = 30 / -8

Reduce the fraction by dividing both numbers by 2:

X = -15/4 or - 3 3/4

6 = x +2/3

Subtract 2/3 from both sides:

x = 5 1/3

13 + w/7 = -18

Subtract 13 from both sides:

w/7 = -31

Multiply both sides by 7:

w = -217

Answer:

1) x = -3.75

2) x = 5.33

3) w = -217

Step-by-step explanation:

1) 17 = -13 -8x

Rearranging the terms of the equation:

=> 8x = -13-17

=> 8x = -30

Computing the value of x:

=> x = -30/8 = -15/4 = -3.75

So the required value of x is -3.75

2) 6 = x +2/3

Rearranging the terms of the equation:

=> x = 6-2/3

    x = (18-2)/3

Simplifying:

    x = 16/3 = 5.33

So the required value of x is 5.33

3) 13 + w/7 = -18

Rearranging the terms of the equation:

=> w/7 = -18-13 = -31

Computing the value of w:

=> w = -31 * 7 = -217

So the required value of w is -217

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters
Vera_Pavlovna [14]

Answer:

The approximate length of the actual car is <u>43 feet</u>.

Step-by-step explanation:

Given:

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters.

Now, to find the approximate length of the actual car.

Let the actual length of the car is x.

The length of a model car in the set is 150 millimeters.

As, given the scale on a model railroad train set is 3.5 millimeters to 1 foot.

<em>So, 3.5 millimeters equivalent to 1 foot.</em>

<em>Thus, 150 millimeters to </em>x<em>.</em>

Now, to get the actual length of the car by using cross multiplication method:

\frac{3.5}{1} =\frac{150}{x}

<em>By using cross multiplying we get:</em>

3.5x=150

<em>Dividing both sides by 3.5 we get:</em>

x=42.85\ feet.

<em><u>The approximate length of the actual car = 43 feet.</u></em>

Therefore, the approximate length of the actual car is 43 feet.

A triangular region of the community college parking lot was measured. The measure of the first angle of this triangle is double
dexar [7]
The key to word problems like this is to turn them into an equation, then they are much simpler to solve.
The first angle is is double the second, so it will be 2x and the second angle will be x. The third angle is 19 more than double the measure of the first angle. that means its 4x +19.
