Select the correct systems of equations.

what angle is half of its supplement; the measure of one angle is 15 less than half the measurement of its supplement; complemen

Delvig [45]

So one angle is of measurement 130 degree and the other angle is of measurement 50 degree.

<h3>What are angles?</h3>

When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.

When two lines meet at a point, an angle is created.

An "angle" is the measurement of the "pening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.

Angles are a common occurrence in daily life.

Angles are used by engineers and architects to create highways, structures, and sports venues.

According to our question-

One angle's measurement is 15 less than its supplement's measurement.

Let's say that the supplement angle is measured in degrees.

So the measurement of the other angle is

And the sum of the measurement of supplementary angles is 180.

Multiplying both sides by 2

Therefore, one angle is 130 degrees in length and the other is 50 degrees.

A rental car agency charges a flat fee of $124.00 plus $45.00 per day to rent a certain car. Another agency charges a fee of $36

irina [24]

x=quantity of days

$38.00+$2.75x=$31.75+$4.00x

We can cancel all $...

38.00+2.75x=31.75+4.00x

It is just as important to cancel symbols as numbers.

Next, we isolate x.

We will begin by subtracting 31.75 from both sides...

-31.75+38.00+2.75x=4.00x

6.25+2.75x=4.00x

Then, we will divide both sides by 4.00...

(6.25/4.00)+((2.75x)/4.00)=(4.00x)/4.00

1.56+0.69x=x

Then, we will subtract 0.69x from both sides...

-0.69x+1.56+0.69x=x-0.69x

1.56=0.31x

Then, we will divide both sides by 0.31...

1.56/0.31=(0.31x)/0.31

5=x

Let's check our numbers...

The original equation was...

$38.00+$2.75x=$31.75+$4.00x

38.00+2.75(5)=31.75+4.00(5)

38.00+13.75=31.75+20.00

51.75=51.75

Answer:

Answer for 1 is x=10 and y=6

Step-by-step explanation:

Basically if you divide the ratio by the side then you should get your answer so 1:2 is basically 1/2

Beatrice has at least one quarter, one dime, one nickel, and one penny. She has exactly 13 coins total. Beatrice also has a tota

prohojiy [21]

Answer:

(Q, D, N, P) = (0, 7, 4, 2) or (1, 3, 7, 2)

Step-by-step explanation:

Let the numbers of coins be Q, D, N, P

We have:

Q + D + N + P = 13

25Q + 10D + 5N + P = 92

Obviously, P = 2, so

Q + D + N = 11 (1)

25Q + 10D + 5N = 90

Divide by 5 and get

5Q + 2D + N = 18 (2)

(2) - (1), get

4Q + D = 7

Let D = 7, Q = 0, from (1), N = 4, so the set is (Q, D, N, P) = (0, 7, 4, 2)

Let D = 3, Q = 1, from (1), N = 7, so the set is (Q, D, N, P) = (1, 3, 7, 2)

If D = 6, 5, 4, 2, 1, 0, Q is not an integer, these can be ignored.
