What is the justification for step 2 in the solution process?

Mathematics
1 answer:
igomit [66]3 years ago
3 0

Answer:

y = 11

Step-by-step explanation:

Solve for y

12y - 40 - 4y = 6y - 18

8y -40 = 6y - 18

8y - 6y - 40 = -18

2y - 40 = -18 ( the justification for step 2 is to isolate y on one side of the                   equation in order to solve for y )

2y - 40 + 40 = 40 - 18

2y = 22

2y/2 = 22/2

y = 11

Check :

12(11) - 40 - 4(11) = 6 (11) - 18

132 - 40 - 44 = 66 - 18

48= 48

A researcher interested in Springfield citizens' shopping habits surveys a randomly selected group of 200 Walmart shoppers. 76%
luda_lava [24]

Answer and Explanation: The results of the survey would not be accurate to the whole of springfield, as the sample was not a random sample. A random sample is where each person in a given area (Springfield in this case) has an equal chance of being surveyed. In this case, only walmart shoppers were surveyed. Therefor, the results can only apply to shoppers at walmart, not the whole of Springfield.

10. A 266-hp output is required for an engine. If there is a 5% loss of power, what amount of input
marta [7]

Answer:

Amount of input horsepower needed is 279.3 hp.

Step-by-step explanation:

if there is a loss of power of 5% the base horsepower will need to be increased by same percentage so that same amount of power can be delivered.

Now to calculate 5% of 266 hp, we can write

266 ×\frac{5}{100} = 13.3 hp

Now to deliver same amount of power we will have to add 5% of 266 hp to its actual power.

So real base power which is needed to deliver 266hp output even at a loss of 5% will be = (266+13.3) hp = 279.3 hp

To know more about horsepower and percentage problem:
