Answer: Yes! those are indeed apart of the fact family

Step-by-step explanation:

Notice that 9+5=14 and 5+9=14, thus the first two equations

show that if we add two numbers in any order, we get the same answer.

Notice that 14-9=5 and 9+5=14, so subtraction and addition are

related. Similarly 14-5=9 and 5+9=14

Notice that 14-9=5 and 14-5=9, so if you subtract one of the

members of the fact family from 14, you get the other.

Hi can you help me please?)
Ad libitum [116K]

<em>To solve for a variable, you just need to isolate the variable to one side.</em>

<h3>7.</h3>

For this, just divide both sides by r and <u>your answer will be \frac{d}{r}=t</u>

<h3>8.</h3>

For this, divide both sides by nR and <u>your answer will be \frac{PV}{nR}=T</u>

<h3>9.</h3>

Firstly, multiply both sides by T: AT=FV-OV

Next, subtract FV on both sides of the equation: AT-FV=-OV

Lastly, multiply both sides by -1, and <u>your answer will be -AT+FV=OV</u>

<h3>10.</h3>

Firstly, multiply both sides by 1000: 1000C=Wtc

Lastly, divide both sides by tc and <u>your answer will be \frac{1000C}{tc}=W</u>
