<u>C. 42 units</u>
Step-by-step explanation:
I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.
To do this, you will multiply the length of AE by 2 and set it equal to BD.
Then distribute, multiply what is in the parentheses by 2.
Subtract 4x from both sides.
Subtract 2 from both sides.
x = 8
Now that we have x, we can plug it into the equation to find BD.
BD is equal to 42 units, so we know...
<u><em>AC = 42 units</em></u>
There are 12 coins in the bag. For the first case, the probability that a penny is selected from the bag is 5/12 because there are 5 pennies in the bag. Also, the next one is 3/11. Multiplying the probabilities,
(5/12)(3/11) = 8/121
I can't explain it but if you need me to explain it I can but here is my work.
Answer:
Three times a number plus 16
To solve this, we simply need to break down the words and turn each part into an equation.
"Three times"
This shows that we will be multiplying 3 and something.
3*
"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n
"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16
Using the logic above, we can see that the equation to represent this is 3n+16.
Answer: Y = -10
Step-by-step explanation:
-x + y = -27
-17 + y = -27
+17 +17
Y = -10
You can also check your work by plugging in the X and Y values and it should equal -27 . So -17 + -10 equals -27.
