In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 80° angle and the 60° angle.

Write and solve an equation to determine the measure of angle x. (5 points)

Answers

Answer:

x = 40°

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

Then we have following equation to solve for x:

x + 60° + 80° = 180°x + 140° = 180°x = 180° - 140°x = 40°
X = 40 degrees

How do you convert 18x − 17y = 18 into slope intercept form?

Answers

Answer:

[tex]y=-\frac{18}{17} + \frac{18}{17} x[/tex]

Step-by-step explanation:

First move x terms and numbers on one side, keep y on the other side.

y = mx+b is the form

18x -17y = 18

subtract 18x from both sides

-17y = 18 - 18x

divide both sides by -17

y = -18/17 + 18/17x

Write an expressions for the missing dimension of each shaded figure and a multiplication expression for it's area

Answers

Answer:

alrighty then, x has to be 14, so x-3=11 which means the question mark would be 3. you can do the rest yourself, I believe in you!

Step-by-step explanation:

To solve this problem, we are required to write and expression to solve for the missing side in each figure.

Side of a Square

To find the missing side of the square, we can simply write it as

[tex]15 = h + x\\x = (15 - h)m[/tex]

For the triangle, to find the missing side let's calculate the area of the triangle

[tex]area = \frac{1}{2} base * height\\area = \frac{1}{2} * 5 * 12\\area = 30m^2[/tex]

But for the length of the missing side, we can simply write it as

[tex]b = 10 + x\\x = (b - 10)m[/tex]

The expressions for the missing sides are;

x = (15- h)mx = (b - 10)m

Answer:

D.

Step-by-step explanation:

Form an equation. 593 = 418 + 12.50d

The variable d represents how many days she needs to pet-sit for.

Use the subtraction property of equality by removing 418 from both sides.

593 - 418 = 418 - 418 + 12.50d

175 = 12.50d

You will need to divide both sides by 12.50 to get the variable by itself.

14 = d

You've gotten the answer now, 14.

Answer: The speed of the car is 45.3 miles per hour.

Step-by-Step Explanation: Let 'x' be the speed of the car.

60 × 2/3 = 120/3 = 40

30 × 1/5 = 151/5

151/5 /40 = x / 60

151 / 200 = x / 60

=> x = (151×60) / 200

=> x = 45.3

Answer:

The car was traveling at an average speed of 45.3 miles per hour.

Step-by-step explanation:

We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.

We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):

30.2/40=x/60

We then cross multiply:

30.2x60=40(x)

1,812=40(x)

Divide each side by 40

1,812/40 = x

x=45.3
