To answer this question I believe you just need to subtract the two values

-12-(-27) = -12 + 27 = 15

The temperature dropped 15 degrees

hope this helped!

What are the solutions to the equation 0 = x2 - X-6? Select two options

Ganezh [65]

Step-by-step explanation:

x2 - x - 6 = 0

x2 - 3x + 2x - 6 = 0

x(x - 3) + 2(x - 3) = 0

x - 3 = 0. x + 2 = 0

x = 3 x = - 2

Option no 2 and 5 are the correct answer

aisha just received a $40 paycheck from her new job. She spends some of it buying music online and saves the rest in a bank acco

Oduvanchick [21]

The 40 number should represent her paycheck which was $40. Since her paycheck is increasing the saving so it's positive.
The x in this question is the number of Aisha spending. Since the spending is decreasing her saving, then it negative. That means that the more Aisha spend her money, her saving will become less.

Solve the equation for xx. For each step, describe the operation used to convert the equation.

Free_Kalibri [48]

Answer:

x = 6

Step-by-step explanation:

Equation given in the question:

3x − [ 8 − 3(x−1) ] = x + 19

Now,

multiplying the term (3(x-1)) in the equation, we get

⇒ 3x - [ 8 - 3x -3 × (-1)] = x + 19

⇒ 3x - [ 8 -3x +3 ] = x + 19

⇒ 3x - [ 11 -3x ] = x + 19

now,

multiplying opening the bracket [11 - 3x]

⇒ 3x - 11 - (-3x) = x + 19

⇒ 3x - 11 + 3x = x + 19

on adding the terms with same coefficient 'x' on LHS

⇒ (3 + 3)x - 11 = x + 19

⇒ 6x - 11 = x + 19

taking -11 to the RHS

⇒ 6x = x + 19 + 11

⇒ 6x = x + 30

subtracting x both the sides

⇒ 6x - x = x + 30 - x

5x = 30

dividing the both sides by 5

$\frac{5x}{5}= \frac{30}{5}$

therefore,

x = 6
