Answer: 
Step-by-step explanation:
We need -9x on the left side, to move it, we must add 9x on both sides.
Done. We have Ax = 9x, By = 1y and C after the equal sign = -6
Answer:
General Formulas and Concepts:
<u>Pre-Alg</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
rt - 2n = y
<u>Step 2: Solve for </u><em><u>t</u></em>
- Add 2n to both sides: rt = y + 2n
- Divide both sides by r: t = (y + 2n)/r
Question:
The majority of U.S. car owners still buy American cars." Ideally, what would the sample be in the study that generated this stat?
answer choices
a) Everyone in the United States who owns a car
b) Everyone in the United States who owns an American car
c) A randomly selected group of car owners in the U.S.
d) A randomly selected group of Americans who own American cars
Answer:
A randomly selected group of car owners in the U.S.
Step-by-step explanation:
In this study, we are told the majority of U.S car owners still buy American cars. The sample in the study that generated this stat would be "a randomly selected group of car owners in the U.S".
⬤ Option A is incorrect, because collecting a sample from every car owner in U.S is impossible as the sample size would be rather tool large.
⬤ Option B is also incorrect because just like in option A, the sample size would be too large. Also this does not take into consideration those who don't use American cars
⬤ Option D is incorrect, this study deals with all car owners in the U.S, not Americans who own American cars. Therefore selecting a sample from Americans who own American cars would be wrong.
It would take 2 hours. To complete the whole lawn you would need:
To make a whole, so to get that we multiply:
So we use the same number required for the whole lawn, and multiply it times the hours
Step-by-step explanation:
let's say, 7 - 4 = 3
that contradicts the statement that both numbers are odd.
no, they are 7, 4, with 4 being even (and not odd).
in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.
odd with odd always delivers an even result. as does even with even.
