Answer:
x = -3
Step-by-step explanation:
To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:
55 + 54 + (x + 74) = 180
We add like terms:
109 + (x + 74) = 180
Continue adding like terms:
183 + x = 180
Next, we dubtract to siolate the "x" variable:
x = -3
Hope this helps :)
x=-3
Step-by-step explanation:
To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.
Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.
Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.
From here, we subtract 180 from both sides, which would get us x=-3.
To double check that this is correct and that it works, you can plug in the -3 where the x would be.
I hope this helped!! Let me know if you have any further questions.

Mr Lim put some red pens and blue pens into a box . The ratio of the number of red pens to the number of blue pens was 3: 4 .He pet another 20 red pens into the box and the ratio of the number of red pens to the number of blue pens became 2:1 (a) How many red pens were there in the end? (b) How many blue pens were there?
Answers
Answer:
a) There were 32 red pens and b) 16 blue pens.
Step-by-step explanation:
3:4
for 3:4 to be 2:1 we should add 5 in order for it to be 8:4 (2:1)
20 divided by 5 is equal to 4
8:4
8 times 4 is equal to 32
4 times 4 is equal to 16
The number of red pens that were there, in the end, is 32 pens while the number of blue pens that were there, in the end, is 16 pens
If the ratio of the number of red pens to the number of blue pens was 3: 4,
If 20 red pens are added into the box and the ratio of the number of red pens to the number of blue pens became 2:1, this means that the 5 is added to the original ratio to have:
(5+3): 4 = 8:4
The number of red pens in the end = [tex]8 \times \frac{20}{5}=8\times 4 = 32[/tex]
The number of red pens in the end = [tex]4 \times \frac{20}{5}=4\times 4 = 16[/tex]
Hence the number of red pens that were there, in the end, is 32 pens while the number of blue pens that were there, in the end, is 16 pens

x²-6x-72
Step-by-step explanation:

(x×x)-(x×12)+(6×x)-(6×12)
x²-12x+6x-72
x²-6x-72
Answer:
120
Step-by-step explanation:
The rules of multiplication state, that when there are two negatives being multiplied by each other, they become positive. You will multiply -10 x -12, and since there are two negatives, they cancel out.
Now it becomes simple multiplication. Simply multiply 10 x 12, without the negatives since they have been canceled out.
-10 x (-12) = 120

Smiley's Cookies makes the best chocolate chip cookies in town! Yesterday, the store sold 7 large cookies for every 5 small cookies. If Smiley's Cookies sold 30 more large cookies than small cookies yesterday, how many small cookies did they sell?
Answers
Answer: The number of small cookies sold = 75
Step-by-step explanation:
GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.
Let 7x be the number of cookies and 5x be the number of small cookies. (i)
They sold 30 more large cookies than small cookies.
i.e. [tex]7x-5x=30[/tex] (Using (i))
[tex]\Rightarrow\ 2x=30\\\\\Rightarrow\ x=\dfrac{30}{2}\\\\\Rightarrow\ x=15[/tex]
Thus, the number of small cookies sold = 5 (15)=75 (Using (i))
Hence, the number of small cookies sold = 75

5/7x - 14 = -22. Find x.
Answers
Answer:
x = -56/5, -11 1/5, or -11.2
Step-by-step explanation:
5/7x - 14 = -22
5x -98 = -154
5x = -154 + 98
5x = -56
x = -56/5, -11 1/5, or -11.2
Answer:
x= -11.2
Step-by-step explanation:
5/7x-14=-22
+14 +14 Add 14 on both sides
5/7x = -8
(7/5)*5/7x = -8*(7/5) Multiply by the reciprocal on both sides to leave x alone

Find cos x and cos y! Please help me out! You don’t need to answer all just what you can :)
Answers
Answer:
7. cos(X) = 3/5 = 0.6
cos(Y) = 4/5 = 0.8
8. cos(X) = 15/17 ≈ 0.8824
cos(Y) = 8/17 ≈ 0.4706
9. cos(X) = 1/2 = 0.5
cos(Y) = (√3)/2 ≈ 0.8660
Step-by-step explanation:
The trigonometric ratio for cosine is given as follows;
[tex]Cos(\theta) = \dfrac{Adjacent\, side \, to\, angle}{Hypothenus\, side \, length \ of\, the \ triangle}[/tex]
7. The adjacent leg length to ∠X = 27
The length of the hypotenuse side of the triangle = 45
∴ cos(X) = 27/45 = 3/5 = 0.6
Cos(X) = 3/5 = 0.6
The adjacent leg length to ∠Y = 36
∴ cos(Y) = 36/45 = 4/5 = 0.8
cos(Y) = 4/5 = 0.8
8. The adjacent leg length to ∠X = 15
The length of the hypotenuse side of the triangle = 17
∴ cos(X) = 15/17 ≈ 0.8824
The adjacent leg length to ∠Y = 8
∴ cos(Y) = 8/17 ≈ 0.4706
9. The adjacent leg length to ∠X = 13
The length of the hypotenuse side of the triangle = 26
∴ cos(X) = 13/26 = 1/2 = 0.5
Cos(X) = 1/2 = 0.5
The adjacent leg length to ∠Y = 13·√3
∴ cos(Y) = 13·√3/26 = (√3)/2 ≈ 0.8660
cos(Y) = (√3)/2 ≈ 0.8660.

But if you do this: 2*(6+4) you do the addition before the multiplication because of the Parentheses and get 20. One small change can make the answer a whole lot more different

If using the method of completing the square to solve the quadratic equation
22 + 15x – 11 = 0, which number would have to be added to "complete the
square"?
Answers
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
22+15x−11=0
Step 1: Simplify both sides of the equation.
22+15x−11=0
22+15x+−11=0
(15x)+(22+−11)=0(Combine Like Terms)
15x+11=0
15x+11=0
Step 2: Subtract 11 from both sides.
15x+11−11=0−11
15x=−11
Step 3: Divide both sides by 15.

Mark took his family to the movies and spent a total of 78$ on tickets he also bought a soda for each family member each sodas cost 4.25 if mark spent a total of 102,50 on sodas and tickets. How much sodas did he buy
Answers
Answer: He bought about 6 sodas.
Step-by-step explanation:
Given: Tota cost of tickets = $ 78
Cost of each soda = $4.25
Total cost of sodas and tickets = 102.50
Let x = Number of sodas purchased
Then
[tex]78+4.25x=102.50\\\\\Rightarrow\ 4.25x=102.50-78\\\\\Rightarrow\ 4.25x=24.5\\\\\Rightarrow\ x= \dfrac{24.5}{4.25}\\\\\Rightarrow\ x\approx6[/tex]
Hence, he bought about 6 sodas.
