The degrees on a triangle add up to 180.

(x) + (x-7) + (3x+12) = 180 ; Just shwoing what i'm doing.

x + x-7 + 3x + 12 = 180

5x + 5 = 180 ; x + x + 3x = 5x , 12 - 7 = 5

5x = 175 ; Subtract 5 from 180

x = 35 ; 175/5 = 35

P: x - 7 = 35 - 7 = 28

Q: 3 (x) + 12 = 3 (35) + 12 = 105 + 12 = 117

R: x = 35

Answer:

  y = 9x

Step-by-step explanation:

We notice that each y-value is a multiple of 9, and the multiple is x.

  y = 9x

20% off means it is selling for 80% of the original price (109% - 20 % = 80%)

Sale price = 6600 x 0.80 = 5,280

Now add the tax:

5280 x 1.05 = 5544

The total price is $5,544

Answer:

[tex]{ \red{ \bold{ = 1 \times 10 {}^{4}}}}[/tex]

Step-by-step explanation:

Step 1: Write the initial number as a product of its first digit and matching place value

[tex] {\red {\bold{10 \: 000 = 1 \times 10 \: 000}}}[/tex]

Step 2: Write 10000 as 10 to the power of 4

[tex]{ \boxed{ \red{ \bold{10 \: 000 = 1 \times 10 {}^{4}}}}}[/tex]

Hence, This is the expanded form with exponents of the initial number !

Answer:

64

Step-by-step explanation:

If you add a positive number that is the same as the negative number together then your answer will end up to be 0.

Answer:

64

Step-by-step explanation:

- 64 + 64 = 0

Adding a positive number to the negative of the same number gives zero

Answer:

10

Step-by-step explanation:

1. The formula to find the slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. All we have to do is plug in the values and simplify.

2. (Solving)

Therefore, the slope is 10.

Answer:

The following expression may be 2(3a^2-2).

Step-by-step explanation:

I factored the following expression 6a^2-4

Answer:

(a) [tex]x=-2,3[/tex] (b) [tex]x=\frac{3}{4} ,-\frac{11}{4}[/tex]

Step-by-step explanation:

[tex]y=x^2-x-6\\y=2x^2+x-6[/tex]

For the first equation, this can easily be factored

[tex]y=(x+2)(x-3)[/tex]

Now, set each of their factors equal to zero and solve

[tex]x+2=0\\x=-2\\\\x-3=0\\x=3[/tex]

Therefore, for a, the roots of [tex]y=x^2-x-6[/tex] are [tex]x=-2, 3[/tex]

For the second equation, it is able to be factored, however, its normally easier to use the quadratic equation to solve polynomials with an a term greater than 1

[tex]y=2x^2+x-6[/tex]

[tex]x_{1} =-b+\frac{\sqrt{b^2-4ac} }{2a}=-1+\frac{\sqrt{1-4(2)(-6)} }{4}=-1+\frac{\sqrt{1-(-48)} }{4}=-1+\frac{\sqrt{49} }{4} =-1+\frac{7}{4}=\frac{3}{4}[/tex]

[tex]x_{2}=-b-\frac{\sqrt{b^2-4ac}}{2a}=-1-\frac{\sqrt{1-4(2)(-6)} }{4} =-1-\frac{\sqrt{1-(-48)} }{4}=-1-\frac{\sqrt{49} }{4}=-1-\frac{7}{4} =-\frac{11}{4}[/tex]

Hope this helps! :)

Answer:

85°

y = 180 - 37 - 58

y = 85

Answer:

85 degrees

Step-by-step explanation:

y+95 degrees=180 degrees

Answer: He's wrong. The solution is x=2

Step-by-step explanation:

4x-4=12-4x

8x-4=12

8x=16

x=2

Blake's assumption is wrong. x = 2 is the solution.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

We have an algebraic equation,

4(x − 1) = 12-4x.

Simplifying,

4x - 4 = 12 - 4x

8x = 16

x = 2

Therefore, x = 2 is the solution.

so it is basically 2 times 27 or 27 plus 27 witch is 54 you will need 12

Step-by-step explanation:

I HOPE THE ABOVE INFORMATION WILL HELP YOU.

THANK YOU.

Step-by-step explanation:

y2−x2+1=50

Step 1: Add -y^2 to both sides.

−x2+y2+1+−y2=50+−y2

−x2+1=−y2+50

Step 2: Add -1 to both sides.

−x2+1+−1=−y2+50+−1

−x2=−y2+49

Step 3: Divide both sides by -1.

−x2

−1

=

−y2+49

−1

x2=y2−49

Step 4: Take square root.

x=√y2−49 or x=−√y2−49

Answer:

x=√y2−49 or x=−√y2−49

y2+6y+9=x+8

Step 1: Flip the equation.

x+8=y2+6y+9

Step 2: Add -8 to both sides.

x+8+−8=y2+6y+9+−8

x=y2+6y+1

Answer:

x=y2+6y+1

Answer:

x=−2 or x=4

Step-by-step explanation:

Step 1: Subtract x+2 from both sides.

x2−x−6−(x+2)=x+2−(x+2)

x2−2x−8=0

Step 2: Factor left side of equation.

(x+2)(x−4)=0

Step 3: Set factors equal to 0.

x+2=0 or x−4=0

x=−2 or x=4

Answer:

58

Step-by-step explanation:

We are given the arithmetic sequence:-

-12,-7,-2,3,...

First, find the common difference which we can obtain by:-

[tex] \displaystyle \large{d = a_{n + 1} - a_n}[/tex]

Check:-

-7-(-12) = -7+12 = 5

-2+7 = 5

3+2 = 5

Therefore, our common difference is 5.

General Arithmetic Term

[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]

Since we want to find the 15th term, substitute a1 = -12, n = 15 and d = 5.

[tex] \displaystyle \large{a_{15}= - 12 + (15 - 1)5} \\ \displaystyle \large{a_{15}= - 12 + (14)5} \\ \displaystyle \large{a_{15}= - 12 + 70} \\ \displaystyle \large{a_{15}= 58} \\ [/tex]
