Explanation:
The set A U B represents the list of items that are either in set A, set B or both sets at the same time. The "U" is the union symbol.
Set A U B looks like this
A U B = {-10, 8, 12, 26, 29, -8, - 1,5, 26, 36}
I basically started with set A, then tacked on the stuff in set B shown in bold.
From here, we toss out the duplicate item 26 and we can optionally sort the set
A U B = {-10, -8, -1, 5, 8, 12, 26, 29, 36}
We see that the number 18 is not in this final set, which is why choice A is the answer.
--------------------
Put another way: the number 18 is neither in set A nor set B, so it cannot be in set A U B.
Something like -10 is in set A, so it's going to be in set A U B as well. We can rule out choice B for this reason. Choices C and D follow a similar idea as choice B.

jeff makes the generalization that a 10s fact can be broken into two 5s facts. write an equation to test his generalization
Expressions can be simplified by breaking it down into several sub expressions.
The equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]
The original expression is:
[tex]\mathbf{Expression = 10s}[/tex]
Express 10s as 5s + 5s
[tex]\mathbf{10s= 5s + 5s}[/tex]
Apply distributive property
[tex]\mathbf{10s= 5s(1 + 1)}[/tex]
Add 1 + 1
[tex]\mathbf{10s= 5s \times 2}[/tex]
Rewrite as:
[tex]\mathbf{10s= 2 \times 5s }[/tex]
Hence, the equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]

Answer:
The first box is 4, the second box which is above the third box is 12 and the third box is 8
Step-by-step explanation:
To add fractions, you have to find like terms. So, you have to make 1/2 have a denominator of 8.
8/2 is 4, so 1/2 equals 4/8.
Now, the first box above the 8 will be 4.
The second and third boxes will be the sum to 4/8+8/8 which is 12/8.

At which time is the distance between the tip of the hour hand and the tip of the minute hand greater, 2:20 or 2:25?
At 2:25, the distance between the tip of the hour hand and the minute will be greater.
What is the distance between the hour and the minute hand?The distance between the hour hand and the minute hand is measured in degrees and the higher the degree, the greater is the distance between the tip of the hour hand and the tip of the minute hand.
From an hour to another;
The shift in hour = 30°So, starting from 12 toward the clockwise direction, the tip of the hour shift twice; i.e.
= 2 × 30°
= 60°
Now, in 2hr : 20 minutes, the distance is:
[tex]\mathbf{= 60+(\dfrac{20}{60})\times 30^0}[/tex]
= 70°
In 2hr : 25 minutes, the distance is:
[tex]\mathbf{= 60+(\dfrac{25}{60})\times 30^0}[/tex]
= 72.5°
Thus, at 2:25, the distance between the tip of the hour hand and the minute will be greater.

67. If mn + p = m + 3n, what is the value of m when
n = 4 and p = 6? MP 2
A -2
B
2
C 3
D 3.6
O E 6
Answer:
2
Step-by-step explanation:
mn + p = m + 3n, n = 4 and p = 6
m(4)+6=m+3(4)
4m+6=m+12
4m=m+6
3m=6
m=2
Answer:
B) 2
Step-by-step explanation:
Step 1: Plug in the values of n and p.
[tex]m(4) + 6 = m + 3(4)[/tex] [tex]4m + 6 = m + 12[/tex]Step 2: Subtract m from both sides.
[tex]4m + 6 - m = m + 12 - m[/tex] [tex]3m+6=12[/tex]Step 3: Subtract 6 from both sides.
[tex]3m + 6 - 6 = 12 - 6[/tex] [tex]3m = 6[/tex]Step 4: Divide both sides by 3.
[tex]\frac{3m}{3} = \frac{6}{3}[/tex] [tex]m = 2[/tex]Step 5: Check if solution is correct.
[tex](2)(4)+(6)=(2)+3(4)[/tex] [tex]8 + 6 = 2 + 12[/tex] [tex]14 = 14[/tex]Therefore, the answer is B) 2.
