Fast ! 10 show work for ! # each !

Note that when there is a negative & positive sign, the sign would become negative. When there is two negative signs directly next to each other, it would become positive.

1. First, find common denominators, what you do to the denominator, you do to the numerator.

(5/9) - (1/3) = (5/9) - (1/3)(3/3) = (5/9) - (3/9) = 2/9

2. In the case of multiplication and division, you do not need common denominators. Multiply across, and simplify.

(2/5)(3/4) = 6/20 = (6/20)/(2/2) = 3/10

3. Simplify. Combine the numbers.

-4.6 + (-8.1) = -4.6 - 8.1 = -12.7

4. Simplify. Combine the numbers.

102 + (-35) = 102 - 35 = 67

5. Simplify. Combine the numbers.

8 - (-3) - 10 = 8 + 3 - 10 = 11 - 10 = 1

6. Note the variables. Combine numbers with the same amount of variables.

10 - 5 - 2x + 4x = 5 + 2x

~

two data sets with the same median will not have the same varaibility

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
