Which of the following is an example of an open equation?
An open equation is an equation with at least one variable.
Therefore, 5x + 7 = 12 is an open equation.

Which of the following equations has 3 as a solution
z ‒ 15 = ‒12
z = -12 + 15 = 3

Is (1, 5) a solution to the equation y = x – 2?
5 ≠ 1 - 2
-5 ≠ -1
no

Is (–2, –6) a solution to the equation y = 3x?
-6 = 3(-2)
yes

Which of (3, 5), (4, 6), (5, 7), and (6, 8) are solutions to y = x + 2
5 = 3 + 2
6 = 4 + 2
7 = 5 + 2
8 = 6 + 2
all

Which equation would be used to generate the data in the following table?
x y
1 8
2 16
3 24
4 32
y = 8x

<RQT is a straight angle. What are m<RQS and m<TQS​
never [62]

Answers:

  • x = 11
  • angle RQS = 106 degrees
  • angle SQT = 74 degrees

===========================================================

Explanation:

Straight angles are always 180 degrees in measure.

The two smaller angles shown add up to 180

(angle RQS) + (angle SQT) = angle RQT

(9x+7) + (6x+8) = 180

(9x+6x) + (7+8) = 180

15x+15 = 180

15x = 180-15

15x = 165

x = 165/15

x = 11

From here, we then know that,

  • angle RQS = 9x+7 = 9*11+7 = 99+7 = 106 degrees
  • angle SQT = 6x+8 = 6*11+8 = 66+8 = 74 degrees

Note how the two results add to 106+74 = 180 to help confirm the answers.

Convert 11.42424242 … to a rational expression in the form of a over b, where b ≠ 0.
babymother [125]

x =  11\frac{42}{99}

Step-by-step explanation:

11.42424242.... = 11. \overline{42} \\ let \: x = 11. \overline{42} .....(1)\\ 100x = 1142.\overline{42}....(2) \\ subtracting \: (1) \: from \:  (2) \: \\  100x - x = 1142.\overline{42} - 11. \overline{42} \\ 99x = 1131 \\ x =  \frac{1131}{99}  \\x =  11\frac{42}{99}  \\
