D is the answer because if you combine it:

2y + y= 3y

3y= y+y+y

2z+z=3z

3z=3z

Answer:

The answer is C

Step-by-step explanation:

There are 3 y's and there are three z's

3(y+z) means that you are multiplying 3 and y, and 3 and z which gives you 3y+3y

Which also equals y+y+y+3z

ERROR ANALYSIS Describe and correct the error in ﬁnding the x-intercept.

EastWind [94]

The x-intercept is -6

Step-by-step explanation:

In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0

In the given method, x is put equal to zero instead of y as x-intercept had to be found.

Given equation is:

$-2x+3y=12$

$-2x + 3(0) = 12\\-2x +0 = 12\\-2x = 12$

Dividing both sides by -2

$\frac{-2x}{-2} = \frac{12}{-2}\\x = -6$

The x-intercept is -6

the perimeter of a basketball court is 102 meters, and length is 6 meters longer than twice the width, what r length and width.

stepladder [879]

Perimeter = 2(l + w)

Thus,

102 = 2(l + w)

l = 6 + 2w

102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w

Thus, w = 15.

Length = 6 + 2w
= 6 + 30
= 36.

Thus, the length is 36 meters and width is 15 meters.
