Answer:

(x, y) = (18, 5)

Step-by-step explanation:

Assuming the three lines meet at a single point at lower left (the figure is sloppily drawn), the angle (3x)°+49° is a corresponding angle to (7x-23)°. That means they have the same measure:

3x +49 = 7x -23

72 = 4x . . . . . . . . . add 23-3x

18 = x . . . . . . . . . . . divide by 4

Angles (3x)° and (11y-1)° are "corresponding" angles, so are congruent.

3x = 11y -1

3(18) +1 = 11y . . . . add 1, fill in the value of x

55/11 = y = 5 . . . . divide by 11

The values of x and y are 18 and 5, respectively.

7 1/4 + 5 3/5= reduced to it's lowest form

Scrat [10]

7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20

The city's elevation is 23.5 feet below sea level. Between which 2 integers is the elevation.

Galina-37 [17]

I believe -23 and -24 because it is below sea level.

12-(4) - 1<br> 2<br><br> Please helppp!!! :)

Kryger [21]

Answer:

Step-by-step explanation:

Simplify:

$12\frac{1}{2} = \frac{25}{2}$

$-4\frac{1}{2} = \frac{-9}{2}$

$\frac{25}{2} - (\frac{-9}{2} ) = \frac{25}{2} + \frac{9}{2} = \frac{34}{2} = 17$

When you have a subtraction sign next to a negative number, the negative number will turn positive since it's understood as -1 multiplied by the number when it's a negative number.

This image of a physics problem shows a block resting on a ramp, . ∠P is the angle between the ramp and the horizontal, and is o

m_a_m_a [10]

Based on the image description, the quantity that is equal to cos W is sin P.

<h3>What is the image about?</h3>

The image is known to be showing an object on a ramp. Based on it, we can therefore take the angle a to the complementary angle of angle w.

Note that the angle w and angle b are said to be the same via alternate interior angles. Therefore, the quantity that is equal to cos W is sin P.
