Answer:

x =5

Step-by-step explanation:

To solve for x:

1: add like-terms

6x+ 12x = 90

Now it is: 18x =90

2: use division on both sides to solve for the variable

18x= 90

18x/18 = 90/18

What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the correspond

Brrunno [24]

Answer: Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

$A=l\times w$ , where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

$A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2 \text{Rounded to the nearest tenth}$

Therefore, the area of rectangle = $13.6\text{ cm}^2$

Three points, A, B, and C exists in space such that B is "between" A and C. It is known that AB=7, BC=4, and AC=9. Are points A,

EleoNora [17]

If the points are collinear, then that would mean that the points lie on the same line when joined to each other. In order to confirm this, the distances between the points must sum up to the length of the line.

AB + BC = AC
7 + 4 ? 9
11 ≠ 9

Since they do not sum up, therefore, the points are not collinear.

PLEASE HELP! All links will be reported!

kozerog [31]

SI =[PRT]/100
Interest = $15.62
Principal = $31
Time = 8
15.62 =[31 x R x 8]/100
15.62 x 100 = [31 x 8 x R]
[15.62 x 100] / [31 x 8] = R
1562/248 = R
6.298 = R
To the tenth
6.3 = R
Check
[31 x 6.3 x 8]/100 = 15.62

Hope that helps
