I think the correct answer is B :)

Answer:

x = -20

Step-by-step explanation:

2(x+7) 2x + 20  - 2 =  x+4  2x + 8

2x+14 + 2x + 20 - 2 = x + 4 + 2x + 8

4x +32 = 3x + 12

x = -20

Answer:

The answer is They are parallel

Step-by-step explanation:

They have the same slope but different y-intercepts

y = 1/3x - 2

y = 1/3x - 30

Answer:

30° and 150°

Step-by-step explanation:

Given

Parallel lines a and b

Transversal c

Angle = 150°

Required

Determine the list of possible angles

A transversal divides a parallel line into two measure which add up to 180°

Given that one of the angles is 150°, the other angle would be 180° - 150°

Other angle = 180° - 150°

Other angle = 30°

Aside 30° and 150°, there's no other possible angle that can be formed by the given information

Step-by-step explanation:

Answer:

224

Step-by-step explanation:

y=6

Step-by-step explanation:

[tex]75 - 3.5y - 4y = 4y + 6[/tex]

Collect like terms and simplify

[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]

Divide both sides of the equation by-3.5

[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]

Simplify

[tex]y = 6[/tex]

The value of the y in the given equation is 6.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,

75 - 3.5y - 4y = 4y + 6

Combining the like terms,

75 - 6 = 4y + 4y + 3.5y

69 = 11.5y

y = 6

Hence, the value of the y in the given equation is 6.

Answer: 0.3 on khan academy

Step-by-step explanation: ‍♂️

The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

Since Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize this mean

So,

P(box containing prize) = 1/4 = p  =0.25

So,

q=1 - p

= 0.75

And total box (n)=6

Let us assume x be number of prize win.

So,

Probability that he will win exactly two prize is

P(X=2)=  [tex]\binom {6}{2}(0.25)^2(0.75)^4[/tex]

= 0.2966

=0.30(approx)

hence, The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.

Answer:

x = 20

y = 100

Step-by-step explanation:

To figure out x do this.

3x + 2x = 7x - 40 (collect like terms)

5x = 7x -40 (subtract 7x on both sides)

-2x = -40 (divide by -2 on both sides)

x = 20

Plug in to get y

Since 7x - 40 and y are vertical they equal the same amount

7(20) - 40 = y (multiply 7 by 20)

140 - 40 = y (collect like terms)

100 = y

Answer:

No it would not be because two sides added up would not equal the other side

Step-by-step explanation:

Answer:

No it is not.

Step-by-step explanation:

All right triangles follow the Pythagorean theorem [tex]a^2+b^2=c^2[/tex] where the squares of the two shorter sides of the right angle triangle is equivalent to the square of the longest side.

Squares of the two shorter sides:

[tex]9^{2}+15^{2}=306[/tex]

Square of the longer side:

[tex]17^{2}=289[/tex]

∵ [tex]306\neq 289[/tex], ∴ the triangle is not a right angle triangle.
