Answer:

130

Step-by-step explanation:

You can make a ratio - 325:5, then we can simplify it to 65:1, where we are comparing # of beats in 1 minute. Now, we can just multiply both sides by two, getting us 130:2, which is just 130 beats.

Which of the following expressions shows how to rewrite 5 − 6 using the additive inverse and displays the expression correctly o
Andru [333]

The correct display of the expression on a number line is number line (c)

<h3>How to determine the expression that shows how to rewrite 5 − 6 using the additive inverse?</h3>

The complete question is added as an attachment

The expression is given as:

5 - 6

Put 6 in a bracket.

So, we have:

5 - 6 = 5 - (6)

Express 6 as --6

So, we have:

5 - 6 = 5 - -(-6)

Rewrite as:

5 - 6 = 5 + (-6)

The above means that the arrow on the number line must start from 5 and moves in the negative direction in 6 units

The correct display of the expression on a number line is number line (c)

4×+12=36 what number goes in the x?
Nataliya [291]
You can work this out by rearranging the equation and isolating the x.

4x + 12 = 36

4x = 36 - 12 (I moved the +12 to the other side, which means it becomes -12)

4x = 24 (36 - 12 = 24)

x = 24 / 4 (You need to isolate the x, and because it was being multiplied by 4, I divided both sides by 4 to leave me with just x)

x = 6 (24 divided by 4 is 6).
