Evaluate -3(8).

Mathematics

Answer: -24

Step-by-step explanation: When you're asked to multiply

positives and negatives together, the rules are simple.

positive times a positive is a <u>positive</u>

positive times a negative is a <u>negative</u>

negative times a positive is a <u>negative</u>

negative times a negative is a <u>positive</u>

One way that I think will help you is to think

about the problem in terms of the signs.

If the signs are the same, the product will always be positive.

For example, (+3) · (+6) = +18 and (-6) · (-2) = +12.

If the signs are different, the product is negative.

So (+6) · (-4) is -24 and (-10) · (+5) is -50.

So don't get caught up on the signs.

Do the problem first, then determine if the

signs are the same or if they are different.

In a recent year, 31% of all college students were enrolled part-time. If 8.6 million college students were enrolled part-time t
Ronch [10]

Answer:

28 million college students.

Step-by-step explanation:

We can represent all college students as x. This means that all part-time college students are \frac{31}{100}x. Because all part-time college students are also equal to 8.6 million, we have 8,600,000=\frac{31}{100}x. To find the number of total college students, or x, we have to multiply by 100/31 to get rid of the fraction on the other side:

8,600,00\cdot\frac{100}{31}=x

The left side of the equation evaluates as 27,741,935.5. Because we are asked to round to the nearest million, we have to round to 28 million, which is the closest.

For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What
Debora [2.8K]

Answer:

The answer is A.

Step-by-step explanation:

So we have the two equations:

3x+y=1\\y+4=5x

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

y+4=5x\\y=5x-4

Now, we can substitute this into the first equation. Therefore:

3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1
