you add the amount of people in each section that fits into the category. So, 11 people from 6-6:29 and 15 people from 6:30-6:59 and then 8 people from 7:30-7:59 so you get 34 people total

9/15+2/5 need help adding fractions
GenaCL600 [577]

Answer:

15/15 aka 1

Step-by-step explanation:

9/15 and 2/5

keep the 9/15 and then denominator the bottom number has to be the same as the first one so multiply 5 times 3 to get 15 whatever you do to the bottom you have to do to the top so 2 times 3 equals 6.

9/15 and 6/15

9+6 equals 15

15/15 which then equals 1

What is the sign? Thank you
Kay [80]

For simplicity, disregard the fractions.  Then you have 48 + (- 39), since opposite signs change into a negative sign, you have 48 - 39.  What is the answer?

POSITIVE

Someone plzzzz helppppppp idkk wat to do
Oksi-84 [34.3K]

Answer:

9x/4= -9

Mutiply by 4 for both sides.

4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36

9x= -36

Divide by 9 for both sides

9x/9= -36/9

x= -4

4x + 1 -5x =2x +4(x-5)
Sunny_sXe [5.5K]

Answer:

x = 3

Step-by-step explanation:

To answer for x first distribute the 4 in the parenthesis

4x + 1 - 5x = 2x +4x - 20

Next add or subtract the x's

-x + 1 = 6x - 20

Now subtract 6x and 1 on both sides to get x on the left and the rest on the right

-7x = -21

Lastly, divide -7 on both sides

x = 3
