x = $\frac{25}{3}$

simplify left side by collecting like terms

2.9x - 8.1 = 6.9 + 1.1x ( subtract 1.1x from both sides )

1.8x - 8.1 = 6.9 ( add 8.1 to both sides )

1.8x = 15 ( multiply both sides by 10 )

18x = 150 ( divide both sides by 18 )

x = $\frac{150}{18}$ = $\frac{25}{3}$

Answer:

Step-by-step explanation:

0.2x+2.7x−8.1 = - 5.2x and 6.9+1.1x = 8

Ig you add them it would be 2.8

What is the surface area?

mash [69]

$\large\bf{\underline{Answer:}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{ = 3000 \:ft^2}$

__________________________________________

$\large\bf{\underline{Given:}}$

A 3 dimensional figure with 5 sides
it has 3 rectangles with dimensions 28 ft and 25 ft
And 2 triangles with base =30 ft and height = 20 ft

$\large\bf{\underline{To\: find:}}$

Total surface area of figure

$\large\bf{\underline{Therefore:}}$

$\bf{area \:of\: figure}$

‎ㅤ ${\bf = area \:of \:3\: rectangles + 2 \: triangles}$

$\large\bf{\underline{Formulas:}}$

$\boxed{\bf\pink{area\:of\: triangle= \frac{1}{2}\times base\times height}}$

$\boxed{\bf\pink{area\:of\: rectangle=length\times breadth}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3\times (28 \times 25 )+ 2(\frac{1}{2} \times 30 \times 20)}$

GEOMETRY 10TH GRADE NEED HELP ASAP

Maru [420]

$\boxed{(6, -3)}$

Step-by-step explanation:

Given the ratio 5:3

and Points A and B where A is located at (-6, 3), and B is located at (26, -13).

Let point A be $(x_{1}, y_{1})$ , and let point B be $(x_{2}, y_{2})$ .

(-6, 3) → $(x_{1}, y_{1})$ .

(26, -13) → $(x_{2}, y_{2})$ .

Let 5 be n, and 3 be m.

5:3 → n:m

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ .

To solve, just substitute these variables into the expressions of these coordinates to get the answer.

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ →

$(\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)})$ →

$(\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)})$ →

$(\frac{-30 + 78}{8}, \frac{15+ -39}{8})$ →

$(\frac{78 – 30}{8}, \frac{15 – 39}{8})$ →

$(\frac{48}{8}, \frac{-24}{8})$

→

$(\frac{6}{1}, \frac{-3}{1})$

→

$(6, -3)$ .

Thus the coordinates of B are:

$\boxed{(6, -3)}$
