Is 0 a solution to 2x+10 = 4x+10 explain or show your reasoning

1 answer:

3 0

0 is considered a solution because when you multiply both 4 and 2 by 0, you always get 0. when you add 10 to 0 you get zero, meaning that you get the same answer for both sides.

La presa de Hidroituango tiene una altura de 225 m., alberga 20 millones de m^3 de volumen y una cresta de 550 metros de longitu

bija089 [108]

Answer:

El ancho de la superficie = 444,44 my el largo = 200 m

La superficie de la superficie de la presa = 88888,89 m²

Step-by-step explanation:

Los parámetros dados son;

La altura del agua en la presa = 225 m

El volumen de agua en la presa, d = 20 millones de m³

La longitud de la base = 200 m

Sea el ancho de la presa = x

El volumen viene dado por la relación;

200 × 225 × x = 20 millones de m³

x = 20.000.000 / (200 × 225) = 444,44 m

Por tanto, las dimensiones de la superficie son ancho = 444,44 my largo = 200 m

El área de superficie de la superficie de la presa = 444.44 × 200 = 88888.89 m².

I need help with the solution to the problem

LUCKY_DIMON [66]

Answer:

(-1,2)

Step-by-step explanation:

The solution to the system graphed is where both of the lines intersect. That's because the intersecting point means that when you substitute x into both of the equations, you'll get the same y value.

If you look on the graph, the intersecting point is (-1,2)

A carpenter needs to cut four sections, each 3–feet 8–inches long, from a piece of molding. If the board is only sold by the foo

KIM [24]

Alright, lets get started.

The length of each section what carpenter needs to cut is 3 feet and 8 inches.

Converting 3 feet and 8 inches into feet only, we know, $12 inches = 1 feet$

So, 3 feet 8 inches = $3 +\frac{8}{12} =3 +\frac{2}{3} =\frac{11}{3}$ feet

It means length of each section = $\frac{11}{3}$ feet

Carpenter needs to cut 4 sections, so length of 4 sections will be = $4*\frac{11}{3}=\frac{44}{3}=14\frac{2}{3} feet$

2/3 feet means 8 inches so she needs board 14 feet 8 inches

Board is only sold by the feet only so, she has to puchase 15 feet board. : Answer

Hope it will help :)
