$3x-y=2 \\ x+y=6 \\ \\4x=8\Longrightarrow x=\boxed{2}$

The x coordinate is equal to 2.

Here we used elimination to eliminate y by adding both equations.

Hope this helps.

A movable section of stage has the shape of an isosceles right triangle. You need to apply 2 coats of paint to all but the botto

Artemon [7]

Answer:

You need to buy 13 quarts of paint

Step-by-step explanation:

The correct question is

A movable section of stage has the shape of a right triangle. You need to apply 2 coats of paint (Assume you will not paint the bottom of the ramp). The paint covers approximately 80 square feet per quart. How many quarts of paint do you need to buy?

The picture of the question in the attached figure

step 1

we know that

The figure show a triangular prism

The surface area of the triangular prism is given by

$SA=2B+PL-(14)(19.5)$ ----> (the area of the bottom is not included)

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the prism

we have

$B=\frac{1}{2}(14)(6)=42\ ft^2$

$P=14+6+15.2=35.2\ m$

$L=19.5\ ft$

substitute

$SA=2(42)+35.2(19.5)-(14)(19.5)=497.4\ ft^2$

step 2

You need to apply 2 coats of paint

Multiply the surface area by 2

$497.4(2)=994.8\ ft^2$

step 3

Divide the total square feet by 80 square feet per quart

$994.8/80=12.4\ quarts$

Round up

You need to buy 13 quarts of paint

What is the answer please

just olya [345]

Answer:

RVS is equal to 180 - 26 degrees, or 154 degrees.

Bonus: I assume the next part of the question asks you to solve for x, where x is equal to that angle. If so, then the answer is 15:

154 = 10x + 4

150 = 10x

x = 15

Determine f(9/2) for the function f(x)=3x-5

ANEK [815]

Answer:

f(9/2) = 17/2

Step-by-step explanation:

f(x) = 3x-5

let x=9/2

f(9/2) = 3*9/2 -5

f(9/2) = 27/2 - 5

get a common denominator

f(9/2) = 27/2 - 10/2

f(9/2) = 17/2
