Answer:

x = 2, y = 4

Step-by-step explanation:

First we isolate and solve for x

y = 6x-8

y= -3x+10

6x-8 = -3x + 10

9x-8 = 10

9x = 18

x=2

Now we solve for y by inserting x into one of the equations

y = -3(2)+10

y = -6 + 10

y = 4

HELP ASAP. <br><br> I’m so confused can someone tell me what to do on this? I’ll mark brainliest

DENIUS [597]

Answer:

52°: angles 4, 13, 18
128°: angles 1, 3, 14, 17
44°: angles 5, 12, 15
136°: angles 2, 6, 11, 16
84°: angles 7, 10
96°: angles 8, 9

Step-by-step explanation:

Where a transversal (t or u) crosses parallel lines (m and n), there are four angles formed at each intersection. Corresponding and vertical angles are congruent.

Angles in a linear pair are always supplementary. Of course, the angles interior to a triangle always total 180°. These facts let you find the relationships of all the angles in the figure.

Angle 13 corresponds to the given angle 52°, so has the same measure. Angles 4 and 18 are vertical angles with respect to those, so also have the same measure. Angles 1 and 3, 14 and 17 are supplementary to the ones just named, so all have measure 128°.

In the same way, angles on the other side of the figure can be found from the one marked 44°. Angles 5, 12, and 15 also have that measure; and angles 2, 6, 11, and 16 are supplementary, 136°. Angles 7 and 10 finish the triangle interior so that its sum is 180°. That means they are 180° -52° -44° = 84°. Of course, angles 8 and 9 are the supplement of that value, 96°.

In summary:

52°: angles 4, 13, 18
128°: angles 1, 3, 14, 17
44°: angles 5, 12, 15
136°: angles 2, 6, 11, 16
84°: angles 7, 10
96°: angles 8, 9

Several students from boxerville middle stood in a circle, evenly spaced, to play a game. If the 6th student was directly across

myrzilka [38]

Answer:

There were 14 students in the circle

Step-by-step explanation:

* Lets explain how to solve the problem

- The students stood in a circle

∴ The line joining each two opposite students is the diameter

of the circle

- The 6th student was directly across from the 13th student

∴ The 6th student is opposite to the 13th student

- Lets count how many students between 6th student and

13th student

∵ 7th , 8th , 9th , 10th , 11th , 12th students between the 6th

student and 13th student

∴ There are 6 students between them

- Lets count how many students between 13th student and

6th student

∵ 14th , 1st , 2nd , 3rd , 4th , 5th students between the 13th

student and 6th student

∴ There are 6 students between them

∵ There are 6 students between 6th and 13th

∵ There are 6 students between 13th and 6th

∵ There are 2 students in 6th and 13th

∴ The number of the students = 6 + 6 + 2 = 14

∴ There were 14 students in the circle

yesterday Josh sold some boxes of greeting cards. today he sold seven boxes .if he sold 25 boxes in all , how many did he sell

Galina-37 [17]

If he sold 25 boxes in all and he sold 7 today then he would of sold 25 - 7 boxes yesterday. Josh sold 18 boxes yesterday.

Today = 7

Yesterday = 18

Total = 25

7 + x = 25, when x = Yesterdays sold boxes.

Hope this helps :)
