Can someone please help me out? It would really make me happier if you did.
asambeis [7]

Answer:

B) 8 and 24.

Step-by-step explanation:

Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.

Regardless, let's work this out mathematically. Let the first number be <em>a</em> and the second number be <em>b</em>.

Their difference is 16. Hence:

a-b=16

The first number is three times the second number. So:

a=3b

Substitute:

3b-b=16

Solve for <em>b</em>. Subtract:

2b=16

And divide both sides by two:

b=8

So, the second number is 8.

And since the first number is three times the second, the first number is 24.

Our answer is B as expected.

Which expression represents the following statement: x is no less than 0. x&gt;0 x≤0 x≥0 x&lt;0
ki77a [65]

Answer: x ≥ 0

Step-by-step explanation:

First, let's define the symbols used:

a < x              (this means that a is strictly smaller than x)

a > x              (this means that a is strictly larger than x)

a ≤ x              (this means that a is smaller than or equal to x)

a ≥ x              (this means that a is larger than or equal to x)

Now we have the statement "x is no less than 0"

Then x can be equal to zero, or larger than zero, but never smaller than zero.

Looking at the symbols above, we know that we need to use:

x ≥ 0

(this is equivalent to the statement)

Four of the 7 students got a sticker, so you need to turn that into a percent. To do that, divide 7 by 4, which gives you .57. That means that 57% of students got a sticker.
