-8+6 (x-2)+5=9 how do you solve

Mathematics

Simplify -8+6(x-2)+5 to 6(x-2)-3
6(x-2)-3=9

Add the 3 to both sides
6(x-2)=9+3

Simplify 9+3 to 12
6(x-2)=12

Divide both sides by 6
x-2=12/6

Simplify 12/6 to 2
x-2=2

Add 2 to both sides
x=2+2

Simplify 2+2 to 4
x=4

I hope that is what you were asking for. :D

A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km
vitfil [10]

Answer:

3.5hour

Step-by-step explanation:

Average speed = Distance/Time

Given

Distance = 52 1/2 km

Speed = 15km/hr

Required

Time

Substitute the given values in the formula

Time = (52 1/2)/15

Time= 105/2 * 1/15

Time = 105/30

Time  = 3.5hour

hence it will take 3.5hr to travel a distance of 52 1/2km

Find the area of the given quadrilateral.<br> Pls :)
Tasya [4]

I think your teacher may have made a typo. Refer to the diagram below. If we ignore segment ZA for now, we can see a rectangle forms with angle W = angle Y = 90. Also, we can see that WX = 6 is the horizontal base and WZ = 8 is the vertical height.

However, the side opposite WZ (which is XY) should also be 8 cm tall, and not 6 cm. If XY was 6 cm, then point Y would move to where point A is located (and the quadrilateral would be WXAZ instead of WXYZ). This new quadrilateral would not have a 90 degree angle at point Y's new location.

In other words, if we want angle Y to be 90 degrees, then side XY must be 8 units long. I have a feeling this is where the typo is, but your teacher might have been intending to say something else.

Equation M: y = x + 4
sladkih [1.3K]
Solve the system

<span>y = x + 4
y = 3x + 6

Note that both equations have been solved for y.  Thus, you can set y = y, or

x+4=3x+6.  Simplifying, -2 = 2x, or x = -1.

Another way to look at this would be    x + 4 = 3x + 6.</span>
