Answer:

has no solution.

Step-by-step explanation:

you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.

Answer:

infinite solutions  

Step-by-step explanation:

you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.

-7(y= 1.5x - 6) which equals the equation below

-7y= -10.5x-42 then combine the other equation

7y=10.5x+42 and that equals

0=0

Answer:

Step-by-step explanation:

There are 65 seats in row 20, option D is correct.

Given that number of seats in row 3 are 31.

Number of seats in row 6 are 37

We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:

Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)

Rate of increase = (37 - 31) / (6 - 3)

Rate of increase = 2

So, the number of seats increases by 2 seats per row.

To find the number of seats in row 20, we can use the rate of increase:

Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))

Number of seats in row 20 = 31 + (2× (20 - 3))

= 31 + (2 × 17)

= 31 + 34

= 65

Therefore, there are 65 seats in row 20.

Answer: 24 hours - no; because depending on where you are on Earth, you have a  different amount of sunlight.

Step-by-step explanation:

The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.

People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

Step-by-step explanation:

The value of x is 10.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

From the triangle it can be assume that ΔPSR is similar to ΔPQR.

Then, the ratio of corresponding sides of triangles are proportion.

So, PQ/ PS = QR/ RS

9/15 = 6 /x

9x = 90

x= 90/9

x= 10

Thus, the value of x is 10.

Answer:

79 degrees.

Step-by-step explanation:

There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.

68+82+81+82+74+75+91 = 553.

553 / 7 = 79.

Law of sines

Step-by-step explanation:

i took the test

The law of sines can be used to calculate the side h. Hence, option B is correct.

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.

Hence, Hence, option B is correct.

Answer:

31

Step-by-step explanation:

The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.

Answer and Step-by-step explanation:

We know that a is equal to 25.

Let's subtract that from the entire angle measure of line segment AB, which is 180.

180 - 25 = 155.

Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.

155 = 2x + 3x

155 = 5x

31 = x

So, the value of x is 31.
