Answer: It’s C, “x+12=30; x=18 students”
Step-by-step explanation:
If Mr. Wilson has 12 more students than Mr. Star, whatever Mr. Star has (x) plus 12, should equal 30. That would make x, or the amount of students Mr. Star has, 18. This answer is included in option C.

The partial factorization of x2 – x – 12 is modeled with algebra tiles.
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x, 3 are labeled +. 1 tile is in the Factor 2 spot and is labeled + x. 20 tiles are in the Product spot: 1 is labeled + x squared, 3 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 12 tiles below the + x tiles are labeled negative.
Which unit tiles are needed to complete the factorization?
Answers
Answer:
x² – x – 12 = (x – 4)(x + 3)
Step-by-step explanation:
Identify two numbers that add to -1 and multiply to -12, let's call them p and q.
So ax² + bx + c = (x + p)(x + q)
pq = c
p + q = b.
It is easier to find these numbers by finding factors of -12.
This can be done by splitting the number up until all the numbers are prime.
-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)
There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.
We can eliminate them by adding them up.
6 + -2 = 4 ≠ -1 so that can't be it.
-6 + 2 = -4 ≠ -1 so that can't be it either.
-3 + 4 = 1 ≠ -1
therefore p and q are 3 and -4 because 3 + -4 = -1.
so x² – x – 12 = (x – 4)(x + 3)
p = -4, and q = 3.
(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

A
Step-by-step explanation:
Given
6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

Three times a number (n) is 36 less than five times the number (n). What is the number?
Answers
Answer:
18
Step-by-step explanation:
To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.
Now, break it by parts - "three times a number" would be [tex]3n[/tex]. The "is" means that it equals something, giving us [tex]3n =[/tex]. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: [tex]5n -36[/tex]. So, put it all together and it is [tex]3n = 5n-36[/tex].
Next, solve the equation for n. The answer will be the number.
[tex]3n = 5n-36\\0 = 2n - 36\\36 = 2n \\n = 18[/tex]
Thus, the number is 18.

What is 8q+12=4(3+3q)
Answers
Answer:
q = 0
Step-by-step explanation:
8q + 12 = 4( 3 + 3q )
Distributive property
8q + 12 = 4 ( 3 + 3q )
8q + 12 = 12 + 12q
Inverse operations
8q + 12 = 12 + 12q
-8q -8q
12 = 12 + 4q
-12 -12
0 = q
q = 0
Answer:
Q = 0
Step-by-step explanation:
1. Expand.
8q + 12 = 12 + 12q
2.cancle 12 on both sides.
8q = 12q
3. Move all terms to one side.
8q - 12q = 0
4. simplify 8q - 12q to -4q.
-4q = 0
5. Divide both sides by -4.
q=0
therefor, the answer is q=0
