Hey there!

Answer = -14

Explanation:

Let's solve your equation step-by-step.

x + 2 = -12

Subtract 2 from both sides:

x + 2 - 2 = -12 - 2

x = -14

So therefore, that is how you found your answer: x = -14

Gelneren [198K]

Answer:

800

Step-by-step explanation:

38200 would represent the debt, 400m would be the amount he puts into it every month. 800 must be the bonus because it doesn't have a variable and is added to the monthly amount.

The gas tank of a car is filled with a nozzle that discharges gasoline at a constant flow rate. Based on unit considerations of
Cloud [144]

Answer:

It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.

Step-by-step explanation:

The filling time of a gas tank can be given by a first order function in this format:

F(t) = V - r*t

In which F(t) is the current amount of fuel in the tank(in L), V is the volume of the tank(in L), r is the discharge rate of the tank(in L/s) and t is the time in seconds.

Finding the values of the parameters:

The tank is completly empty, so F(t) = 0.

The volume of the tank is 14 gallons. However, the problem states that the volume of the tank is measured in liters.

Each gallon has 3.78L.

So V = 14*3.78 = 53L

The discharge rate for the gas is 38.0 l/min. However, the problem states that the discharge rate is in L/s. So, to find the value of r, we solve the following rule of three.

38 L - 60s

r L - 1s

60r = 38

r = \frac{38}{60}

r = 0.63

Solving the equation:

F(t) = V - r*t

0 = 53 - 0.63t

0.63t = 53

t = \frac{53}{0.63}

t = 84.12s

It is going 84.12s = 1 minute and 24.12 seconds to fill the tank.
