Well you want to distribute the negative sign so it will be a lil easier to solve 

so  -(-w+6) becomes (w-6)

now plug in each value
 a. 3-6 = -3
b. -7-6= -13
c. -3-6= -9
d. 7-6= 1

The sum of two numbers is x. If one of the numbers is 12, what is the other? 12 - x x - 12 12 + x 12 x
igomit [66]

Let

a-------> one of the numbers

b------> the other number

we know that

a+b=x ----> equation A

a=12

substitute the value of a in the equation A

12+b=x

solve for b

Subtract 12 from both sides

12+b-12=x-12

b=x-12

therefore

<u>the answer is</u>

The other number is x-12

Which of the following points is in the solution set of y &lt; x 2 - x - 6?
Georgia [21]
Y< X^-X-6

1. Solve the x first by factor.
2. X equals to (x-3)(x+2). X=3 or -2.
3. Looking at the problem, we see two similar answers with 3 and -2.
4. The correct answer is D, y=0. Because 0 is less than 3, choice A fails because y is greater than x.

The temperature in Miami, Florida is 22 degrees warmer than three times the temperature in Bangor, Maine. The temperature in Mia
Nastasia [14]

Answer:

y=\frac{x-22}{3} ; y=20

Step-by-step explanation:

Let Temperature of Maimi T_{m}  and that of Bangor be T_{b}

Given in the condition is T_{m} is 22 more than 3 times  T_{b}

i.e. T_{m} = 22+ 3 * T_{b}

Hence

T_{m} - 22 = 3 * T_{b}

T_{b} = \frac{T_{m}-22}{3}

Here also we are given that T_{m}=82

T_{b} = \frac{82-22}{3}

T_{b} = \frac{60}{3}

T_{b} = 20
