Answer:

x = 21

Step-by-step explanation:

3x - 71 = 2x - 50

3x - 2x = -50 + 71

x = 21

Check:

3(21) - 71 = 2(21) - 50

63 - 71 = 42 - 50

-8 = -8

Answer: x=21

<u>Subtract 2x from both sides</u>

<u></u>3x-1-2x=2x-50-2x\\x-71=-50<u></u>

<u></u>

<u>Add 71 to both sides</u>

<u></u>x-71+71=-50+71\\x=21<u></u>

find the equation of the line passing through the points (2,4) and (3,2). find both green and grey box
Leto [7]

Answer:

  y = -2x +8

Step-by-step explanation:

The 2-point form of the equation of a line is useful when two points are given.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (2 -4)/(3 -2)(x -2) +4

  y = -2(x -2) +4

  y = -2x +8

What is the simplified expression for 6 (2 (y x))? 6 y 12 x 12 y 12 x 12 y 8 x 8 y 8 x
stellarik [79]

The simplified expression for 6(2( y + x)) is 12y + 12x.

Accordin to the given question.

We have an expression

6(2( y + x))

Therefore,

The simplified expression for 6(2( y + x)) is given by

6(2(y + x))

= 6(2y + 2x)          (by distributive law)

= 12y + 12x              (by distributive law)

Hence, the simplified expression for 6(2( y + x)) is 12y + 12x.

How do I solve this question I’ve been stuck on this since last night
meriva

Observation one

From the markings on the diagram <1 = 60o The left triangle is at least isosceles. Therefore equal sides produce equal angles opposite them.

Now we have accounted for 2 angles that are equal (each is 60 degrees) and add up to 120 degrees. The third angle (angle 2) is found from this equation.

<1 + 60 + <2 = 180 degrees.  All triangles have 180 degrees.

60 + 60 + <2 = 180

Observation 2

<2 = 60 degrees.

120 + <2 = 180

m<2 = 180 - 120

m<2 = 60 degrees.

Observation 3

m<3 = 120

<2 and <3 are supplementary.

Any 2 angles on the same straight line are supplementary

60 + <3 = 180

<3 = 180 - 60

<3 = 120

Observation 4

m<4 = 40 degrees.

All triangles have 180 degrees. No exceptions.

m<4 + 20 +m<3 = 180

m<4 + 20 + 120 = 180

m<4 + 140 = 180          

m<4 = 180 - 140

m<4 = 40
