(-4,5) is the correct answer because it needs to be (-y,x) meaning the original x value stays the same because we’re going backwards and the y value changes signs

Answer please ...................................
jok3333 [9.3K]

Answer:

#1. 8.27

#2. 36

#3. 22

#4. 7.25

Step-by-step explanation:

#1: 60÷11=5.45  ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>

#2: 60÷5= 12 ----> 12×3= <u>36</u>

<u></u>

#3: Games- 35    Won- 14    Lost- 21

      In 1 Game  Manchester won =   14/35  =  2/5 games in 54 Game  Manchester won =  54 x  2/5   games

= 108 / 5

= 21.6

<u>= 22</u>

<u></u>

#4: 6 : 91 ⇒ n : 110

     6(110) ⇒ 91(n)

     660 ⇒ 91n

     660/91 ⇒ n

     <u>7.25=n</u>

<u></u>

What is the first step in the constitution of a line perpendicular to AB and passing through an external point M?
NikAS [45]

take your compass on a point on your line. then draw a circle. take the 2 points in which the circle hit the line and draw 2 circles larger than half the distance between he 2 points. take the point that they intersect and and connect it to the line and you point M and it is purpendicular. does that make sense?

What is the answer to the questions​
loris [4]
<h3>Answer:  x = 40</h3>

===================================================

Work Shown:

A+B+C = 180 ..... three angles of any triangle add to 180

(2x+10)+(x)+(2x-30) = 180

5x-20 = 180

5x = 180+20 .... adding 20 to both sides

5x = 200

x = 200/5 ... dividing both sides by 5

x = 40

This is the measure of angle B

We can stop here.

If you need to know the values of the other angles, then,

  • angle A = 2x+10 = 2*40+10 = 90
  • angle C = 2x-30 = 2*40-30 = 50

Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.
