-7x -7y = 21
Y = 6

Since they are giving you the value of 6 you just plug it in the equation

-7x - 7(6) = 21
-7x - 42 = 21
+ 42. +42

-7x = 63
/-7. /-7

X = -9

Consider the following number line
Sati [7]

<u>Answer:</u>

<h2><u>-2.25</u></h2><h3><u>Step-by-step explanation:</u></h3>

Lets start with D:

It says, 0.43 but we're on the OPPOSITE of 0, so it can't be a positive number.

Same goes for C.

Now we are on to our last two.

B, is -2.5 and A, is -0.8

So, now we look at the point <em>B </em>and <em>assume</em>, because it says Select a reasonable value for Point B.

To me, point <em>B </em>looks to be about around -2.0

So, the <em>reasonable value </em>for this problem would be -2.25

The length of a rectangle is 4 more than 3 times the width if the perimeter of the rectangle is 18.4 cm what is the area of the
garik1379 [7]
Let's call the width: w

the lenght is then 3w+4 ("4 more than 3 times the width")

and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.

this is also equal to 18.4:

8w+8=18.4
8w=10.4
w=1.3

this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9

and the area is their product:
1.3*7.9=10.27
