7x + x + 20 = 180\Leftrightarrow 8x = 160\Leftrightarrow x = 20

Blababa [14]4 years ago
7 0

Answer:

x=20

Step-by-step explanation:

The two angles add together to form a straight line, which is 180 degrees.

7x + (x+20) = 180

Combine like terms

8x+20 = 180

Subtract 20 from each side

8x+20-20 = 180-20

8x =160

Divide each side by 8

8x/8 = 160/8

x = 20

Plot and connect the points A(2,3), B(2,-5), C(-4,-3), and find the area of the triangle it forms.
MAVERICK [17]
Check the picture below.

so we can simply split the triangular area into two smaller triangles, notice their base and height.

so, simply, get the area of each triangle, sum them up, and that's the area of the triangular section.

\bf \stackrel{\textit{yellow triangle}}{\cfrac{1}{2}(6)(6)}~~~~+~~~~\stackrel{\textit{blue triangle}}{\cfrac{1}{2}(6)(2)}

a gas company in massachusetts charges $1.30 for 16.7 ft3 of natural gas. convert this rate to dollars per liter of gas
Katyanochek1 [597]

By using a change of units, we can see that the rate in dollars per liter is:

R = $0.0027 per liter.

<h3>How to convert the rate?</h3>

Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.

The original rate is in dollars per square foot, and it is given by:

R = $1.30 for 16.7ft^3

We know that the relation between cubic feet and liters is:

1ft^3 = 28.32 L

Then, if we apply a change of units, we can rewrite the volume as:

16.7ft^3 = 16.7*(28.32) L = 472.9 L

Then the rate is $1.30 per 472.9 L, taking the quotient we get:

R = ($1.30/472.9 L) = $0.0027 per liter.

How many quarts are in 2 &amp; a half gallons
puteri [66]
Hi there!

Using some simple conversions we can determine how many quarts are in 2 & a half gallons.

1 gallon = 4 quarts.
2 gallons = 8 quarts.

Since we're trying to determine how many quarts are in 2 & a half gallons we can separate our problem into how many quarts are in two gallons and how many are in a half a gallon.

2 gallons = 8 quarts.
.5 gallon = 2 quarts.

After adding this together we come up with the answer that there are 10 quarts in 2 & a half gallons. :)
