Convert 500 cubic feet to liters then to gallons

V125BC [204]

Answer:

500 cubic feet equals 14158.4 liters or 3740.25 gallons.

Step-by-step explanation:

We are asked to convert 500 cubic feet to liters then to gallons.

We know that one cubic feet equals 28.3168 liters.

$\text{500 cubic feet to liters}=\text{500 cubic feet}\times \frac{\text{28.3168 liters}}{\text{cubic feet}}$

$\text{500 cubic feet to liters}=500\times \text{28.3168 liters}$

$\text{500 cubic feet to liters}=\text{14158.4 liters}$

We know one liter equals 0.264172 gallons.

$\text{14158.4 liters to gallons}=\text{14158.4 liters}\times\frac{0.264172\text{ gallons}}{\text{liter}}$

$\text{14158.4 liters to gallons}=14158.4 \times 0.264172\text{ gallons}$

$\text{14158.4 liters to gallons}=3740.2528448\text{ gallons}$

$\text{14158.4 liters to gallons}\approx 3740.25\text{ gallons}$

Therefore, 500 cubic feet equals 14158.4 liters or 3740.25 gallons.

Of the four choices given, which two, when written as a system, have a solution of (-4,5)?

Svetach [21]

Answer:

both choices with 2x+y = -3

Step-by-step explanation:

to have the solution (-4, 5), that point must be on both equations/functions, meaning it must be on either one.

in other words, if the point is not on at least one of the functions, it cannot be a solution for that system.

the given function

2x + y = -3

looks like for the point (-4, 5)

2×-4 + 5 = -3

-8 + 5 = -3

-3 = -3

correct.

but

-2x + y = -3

looks like for (-4, 5)

-2×-4 + 5 = -3

8 + 5 = -3

13 = -3

wrong. the point is not on this function.

as we can therefore rule out 2 of the answer options, the other 2 most be correct.

Write and solve an equation that represents the following:<br> Twenty more than a number is eighteen

ArbitrLikvidat [17]

Salutations!

Let the number be $x$

The equation would be: $x+20=18$

Lets solve this!

We need to always keep the variables aside, and the numbers aside.

$x=20-18$

$x=2$

Hope I helped (:

Have a great day!
