The answer is mp-n=x. Hope this helps.

To do this, multiply both sides by p to get rid of p on the right side. This gives is pm=n+x. Now just subtract n from both sides, to get the final answer of pm-n=x.

Which number line correctly shows 4. 5 + 2. 5? A number line going from 0 to 4. 5 in increments of 0. 5. An arrow goes from 0 to

sesenic [268]

So none of the options is actually correct from the given operation of:

4.5 + 2.5

This actually would be represented with a line that goes from 0 to 4.5, and then from 4.5 to 7.

The number line should start at 0 and then move to the first number (because of the commutative property of the sum, it can move to any one of the two numbers).

Once there, it moves accordingly to the other number.

So it moves first from 0 to 4.5, then the second number is 2.5, then it moves another 2.5 units to the right until the:

4.5 + 2.5 = 7

Concluding, it moves from 0 to 4.5, then from 4.5 to 7.

Notice that none of the options represent this, this may be because the sign of one of the two numbers is incorrect or something like that.

For example, if we had the operation:

4.5 - 2.5

Then the line starts at 0 and then goes to 4.5, then moves left 2.5 units to 4.5 - 2.5 = 2

In this case, the correct option should be:

"An arrow goes from 0 to 4. 5 and then backwards from 4. 5 to 2."

What is the answer a factory adds three red drops an two blue drops of coloring to white paint to make each pint of purple paint

Elan Coil [88]

Answer:

Red = 30 drops

Blue = 20 drops

Step-by-step explanation:

The ratio red to blue is 3 : 2

Sum of ratios = 3 + 2 = 5

Required purple paint = 50 gallons

So,

$Multiplier = \frac{50}{5} = 10$

Now, Red drops = 3×10 = 30

Blue drops = 2×10 = 20

If f(x) = x2 – 1 and g(x) = 2x – 3, what is the domain of (f circle g) (x)? (negative infinity, infinity) Left-bracket negative

n200080 [17]

Answer:

A. (-∞, ∞)

Step-by-step explanation:

f circle g (x) is another way of expressing f(g(x)). Basically, we have to plug g(x) into f(x) wherever we see x's.

f(x) = x^2 - 1

f(x) = (2x-3)^2 - 1

Now find the domain. I think the easiest way to do this is to graph it. I've attached the graph. You can also do it algebraically by thinking about it: it's a positive parabola (+x^2) and its minimum is -1, so its range will not be all real numbers, but its domain will certainly be. (The range would be answer choice B!)

Domain = (-∞, ∞)
