34 12/27-19 5/6
You may get common denominators.

12*2 = 24
27*2 = 54

5*9=45
6*9 = 54

34 24/54 - 19 45/54
Subtract 19.
15 24/54 - 45/54
14 33/54 = Answer.

First you have to make them both common denominators so you find a number that both work for 27 and 6. I decided to simplify them into improper fractions so I got 930/27 - 119/6 but since that didn't work I found that if I simplified 930/27 to 310/9 then I could use that to get a common denominator and I multiplied both numbers to change the denominator so that I have 1860/36 - 1071/36 = which equals 789/36 which I then simplified to 263/12 I am not sure if you can simplify it further but that is what I got :) hope it helps

3x-2y=-5 and 4x+2y=-16

podryga [215]

Answer:

x=-22/4

y=-3

Step-by-step explanation:

3x-2y=-5

4x+2y=-16

we add the equation

7y=-21

y=-3

then we find the x by taking a random equation

I take 4x+2y=-16

4x+2(-3)=-16

4x-6=-16

4x=-22

x=-22/4

Question 11 (2.5 points)

Rama09 [41]

Answer:

Step-by-step explanation:

The answer is d, because a represents adults, and c represent children. It's $45 per adult, so $45a, and $30 per child, so $30c. a+c is equal to 10, because that's how many tickets were purchased. $45a+$30c=345, because $345 is the total amount spent on tickets.

I need help with #7 ?!!! Btw #6 is correct

Musya8 [376]

Choice C for problem 6 is correct. The two angles (65 and 25) add to 90 degrees, proving they are complementary angles.

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

The answer to problem 7 is also choice C and here's why

To find the midpoint, we add up the x coordinates and divide by 2. The two points A(-5,3) and B(3,3) have x coordinates of -5 and 3 respectively. They add to -5+3 = -2 which cuts in half to get -1. This means C has to be the answer as it's the only choice with x = -1 as an x coordinate.

Let's keep going to find the y coordinate of the midpoint. The points A(-5,3) and B(3,3) have y coordinates of y = 3 and y = 3, they add to 3+3 = 6 which cuts in half to get 3. The midpoint has the same y coordinate as the other two points

So that is why the midpoint is (-1,3)
