Answer: 5x + 4z = 10z - 2x

move variable to the left side and change its sign

5x + 2x + 4z +10

Move variable to the right side and change its sign.                                                                     5x + 2x = 10z - 4z                                                                                                                                                                                                              Collect the like terms                                                                                                   5x + 2x =10z - 4z                                                                                                           ↓                                                                                                                                      7x = 10z - 4z                                                                                                                                                      Collect the like terms                                                                                                                                      ↓                                                                                                                                                                                                                    7x = 6z                                                                                                                                                                                                                                                   Divide both sides of the equation by 7                                                                                                                                                           x = 6/7 z decimal <em>0.857143</em>

Identify and EXPLAIN the ERROR
AveGali [126]

Answer:

Error: Sariah treated every term as though it were an x-term. 5 and -4.5 are constants that cannot be combined with the x-terms. They can only be combined with each other.

Correct solution: 31x + 0.5

Strategy: Pay attention to the variables.

Step-by-step explanation:

In her first step, it appears Sariah added 13x and 5 to get 18x. These terms are not <em>like terms</em>, so cannot be added in this way. An appropriate strategy is to first identify all the terms with the same <em>variables</em> (x in this case), then add their <em>coefficients</em>.

... = x(13 +17 +1) +5 -4.5

Likewise, all the <em>constant</em> terms can be added.

... = 31x +(5 -4.5)

... = 31x + 0.5

Which is a characteristic of the line that passes through the points (6, 10) and (12, 7)?
mihalych1998 [28]

Answer:

Step-by-step explanation:

The general formula of the linear equation is:

y = mx + c 

where m is the slope and c is the y-intercept

1- getting the slope:

We are given the two points:

(6,10) representing (x1 , y1)

(12,7) representing (x2 , y2)

The slope of the line will be calculated as follows:

m = (y2-y1) / (x2-x1) = (7-10) / (12-6) = -3/6 = -0.5

The equation of the line now becomes:

y = -0.5x + c

2- getting the value of the y-intercept:

To get the value of the y-intercept (c), we will use any of the given points, substitute in the equation of the line and solve for c. I will use the point (6,10) as follows:

y = -0.5x + c

10 = -0.5(6) + c

10 = -3 + c

c = 13

Based on the above, the equation of the line would be:

y = -0.5x + 13

Hope this helps :)

PLEASE HELP!! WILL MARK BRAINLEST!!!
miss Akunina [59]

Answer:

x: length

y: wide

x = 3y and x*y =192

=> 3y^2 = 192

=> y = 8 => x =3x8 = 24

=> Perimeter = (x+y)*2 = (8+24)*2 = 64
