Answer: 9= -1.5 or -3/2

               10= -11/6 or 1.8333

                11= -10.9

                 12= 3.535

                   13= Town A is -3.33 Town B is -3 2/5, 2/5= .44, so town B is colder, as it is -3.44

                     14= I'm not sure about number 14, sorry about that

<em>9. </em>

Explanation: So for question 9, you need to find the LCD (Least common denominator) so you list out the multiples of 8 and 4, when doing so, you find out that 8 is the LCD of both, since 8 is both a multiple of itself and of 4.

So, to get the answer, you do 4 * 2 and anything you do to the denominator (bottom number), you do to the nominator (top number).

So now you have -8/3/8 +6/2/8 then you just add the nominators and whole numbers like normal. You get, -2/1/8 (Remember you are adding a positive number to a negative number.)

Answer: -2/1/8

<em>10.</em>

Explanation: Same process as question 9.

Answer: -4/1/12

<em>11. </em>

Explanation: Read -7.3 out loud, it would be negative seven and 3 tenths, that makes it easy to convert as a fraction. It would be -7/3/10. Do the same for the other number, and you have -3/6/10, then you just add. You get -10/9/10.

Answer: -10/9/10

<em>12. </em>

Explanation: Same process as question 11. (You're in the thousandths now.) You get 3/535/1000. Reduce.

Answer: 3/107/200

<em>13. </em>

Explanation: You have 2 options here, to convert the decimal into a fraction, or to convert the fraction into a decimal, I'll be changing the fraction into a decimal, you wanna write it as a 10 as a denominator, so to get to 10 you multiply the denominator by 2, and anything you do to the denominator, you do to the nominator. So, -3/2/5 as a decimal is: -3.4, then you go ahead and compare them and you can see that the temperature in town A is colder.

Answer: The temperature in town A is colder.

<em>14. </em>

Explanation: For this one, you just subtract or add the amount to 7number. The dates don't matter, just telling you to do it in that order.

60.68 + 75.50 = 136.18

136.18 - 25.16 = 111.02

111.02 - 82.05 = 28.97

28.97 + 59.95 = 88.92

Answer: $88.92

Because the coefficient of x^2 is -1, we know that a will be -1.  Knowing that the coefficient of x is -4, we can calculate that p=2.  Thus, we have -1(x+2)^2+q is our equation.  This is equal to -x^2-4x-4+q.  As the constant term must be 2, we can then see that q is 6.

As such, we have -1(x+2)^2+6=0 as our factorization.

To solve this equation, we can use the quadratic formula.  Plugging in values, we have:

\frac{4+-2 \sqrt{6} }{-2}
which is equal to: (when the fraction is simplified)
-2+- \sqrt{6}

'Ciumane ananen<br> 32.50t + 5 = 28.75t + 20
gtnhenbr [62]

Answer:

The answer is 0.25

Step-by-step explanation:

(1)we group like terms by subtracting 32.50 by 28.75

(2) we subtract 20 and 5 to give us a value of 15

(3)when we subtract 32.50 and 28.75 we get a value of 3.75

(4)so the equation will look like this 3.75t = 15

(5)we divide 3.75 we both the two equations

(6)With a correct calculation, Your answer should be t = 0.25

The reciprocal would be 9/7 because a reciprocal is when you flip a fraction and put the denominator as the numerator and vice versa.
