Answer:

x=3

Step-by-step explanation:

6(8−2x)=4x

Step 1: Simplify both sides of the equation.

6(8−2x)=4x

(6)(8)+(6)(−2x)=4x(Distribute)

48+−12x=4x

−12x+48=4x

Step 2: Subtract 4x from both sides.

−12x+48−4x=4x−4x

−16x+48=0

Step 3: Subtract 48 from both sides.

−16x+48−48=0−48

−16x=−48

Step 4: Divide both sides by -16.

−16x/−16=−48/−16

I am stuck on 14 and 15 as they do not have a straight line going through to help me, anybody know how to ?? thanks !

Answer:

14. x=21, GK=167°, HJ=98°, HGJ=262°, GKJ=201°

15. x=9, AD=108°, BC=23°, DC=139°, DBC=221°

Step-by-step explanation:

In each case, the sum of the arcs around the circle is 360°.

14. 61 +(5x -7) +34 +(9x -22) = 360

14x = 294 . . . . . subtract 66, simplify

x = 21 . . . . . . . . divide by 14

(5x -7) = 98

(9x -22) = 167

x = 21
arc GK = 167°
arc HJ = 98°
arc HGJ = 360° -98° = 262°
arc GKJ = 167° +34° = 201°

15. 90 +(2x +5) +(17x -14) +(12x) = 360

31x = 279 . . . . subtract 81, simplify

x = 9 . . . . . . . . divide by 31

(2x+5) = 23

(17x -14) = 139

(12x) = 108

x = 9
arc AD = 108°
arc BC = 23°
arc DC = 139°
arc DBC = 360° -139° = 221°

If 60% of a car company's sales are from SUVs, and they sell a total of 360 cars that are not SUVs, how many SUVs did they sell?

solong [7]

Answer:

540 SUV's

Step-by-step explanation:

Sales percentage of non SUV's = 100 - 60 = 40%

Let total cars be x

40% of x = 360

$\dfrac{40}{100}*x=360\\\\\\x=360*\dfrac{100}{40}\\\\\\x = 900$

Number of SUV's = Total cars - number of non SUV's

= 900 - 360

= 540

The ordered pairs below represent a relation between x and y.(-3,-3), (-2,0), (-1,3), (0,6), (1,9), (2,12)Could this set of orde

GarryVolchara [31]

The set of ordered pairs generate a linear function because all the points lie in the same line that is described by the equation y = 3x + 6. The equation is found by choosing any two ordered pair and constructing the y =mx+b equation form where m is the slobe and b is the y-intercept.
