Answer:
1a) x = -41
1b) x = -1
1c) x = 29/3, or x = 9.66 in decimal form
1d) x = -4
----------------
2a) y = -3
2b) y = -60
2c) y = -83
2d) y = -50
Step-by-step explanation:
1a) y = x + 11
-30 = x + 11
-11 -11
------------------
-41 = x
1b) y = -2x - 32
-30 = -2x - 32
+32 +32
----------------------
2 = -2x
/-2 /-2
----------------------
-1 = x
1c) y = -3x - 1
-30 = -3x - 1
+1 +1
-----------------
-29 = -3x
/-3 /-3
------------------
29/3 = x
9.66 = x
1d) y = 5x - 10
-30 = 5x - 10
+10 +10
----------------------
-20 = 5x
/5 /5
----------------------
-4 = x
------------------------
2a) y = x + 3
y = -6 + 3
y = -3
2b) y = -2x - 72
y = -2(-6) - 72
y = 12 - 72
y = -60
2c) y = 3x - 65
y = 3(-6) - 65
y = -18 - 65
y = -83
2d) y = 4x - 26
y = 4(-6) - 26
y = -24 - 26
y = -50

triangle ABC △ABC triangle, A, B, C is rotated -120° about point P create ΔA' B' C'
Answer:
40°
Step-by-step explanation:
Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.
After rotational transformation, the measure of angle ∠A' = 40°.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The diagram shows the two triangles.
Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.
From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.
Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]
Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of green results for 240 trials.
Red Orange Yellow Green Blue

18
36
54

Answer:
I'd guess 54
Step-by-step explanation:
If the sections are all equal sized, there's an equal chance the arrow/spinner would land on them. If you divide 240 by 5, you get 48. The closest number to 48 is 54.

Step-by-step explanation:
Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies. The rest of the class gets nothing and begins to collectively cry. How many cookies were in the batch, to begin with?
Answer:
36
Step-by-step explanation:
After dylan took half of the cookies and 6 were left there were
12 before he took any
Than If Koji took a 3rd when 12 were left there were 18
Than if Paige took a 1/4 of what was left when there were 18 there were 24
This same pattern is the same for the next 2
24+6 = 30 and than 30+6 = 36
TLDR;
remove 6 per person meaning there were 36 to begin
Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies then the batch initially had 432 cookies.
Mrs. Balbas baked a batch of cookies for her math class.
1. Aaron takes 1/6 of the cookies:
If "C" represents the initial number of cookies, Aaron takes (1/6)C cookies, leaving (5/6)C cookies.
2. Matthew takes 1/5 of the remaining cookies:
Matthew takes (1/5)(5/6)C = (1/6)C cookies, leaving (5/6)C - (1/6)C = (2/3)C cookies.
3. Paige takes 1/4 of the remaining cookies:
Paige takes (1/4)(2/3)C = (1/6)C cookies, leaving (2/3)C - (1/6)C = (1/2)C cookies.
4. Koji takes 1/3 of the remaining cookies:
Koji takes (1/3)(1/2)C = (1/6)C cookies, leaving (1/2)C - (1/6)C = (1/3)C cookies.
5. Dylan takes half of the remaining cookies:
Dylan takes (1/2)(1/3)C = (1/6)C cookies, leaving (1/3)C - (1/6)C = (1/6)C cookies.
6. Gavin takes the last 6 cookies:
The remaining (1/6)C - 6 cookies are taken by Gavin.
7. The rest of the class gets nothing, leaving 0 cookies.
Now, let's add up the amounts taken by each student:
- Aaron: (1/6)C
- Matthew: (1/6)C
- Paige: (1/6)C
- Koji: (1/6)C
- Dylan: (1/6)C
- Gavin: 6 cookies
Adding all these together, we get:
(1/6)C + (1/6)C + (1/6)C + (1/6)C + (1/6)C + 6 = (5/6)C + 6
Since the remaining cookies are accounted for,
we know that (5/6)C + 6 = 0, which gives us C = 432.
Therefore, the initial batch had 432 cookies.
