Murljashka [212]2 years ago
7 0

Step-by-step explanation:

(i). a+(b+c) = (a+b)+c

-35+(10-5) = (-35+10)+(-5)

-35+5 = -25-5

-30 = -30

(ii). a×(b+c) = a×b + a×c

-35 × [10+(-5)] = -35×10 + -35×-5

-35 × (10-5) = -350 + 175

-35 × 5 = -350 + 175

-175 = -175

Help me pls also the answer must be a mixed number
Oksi-84 [34.3K]

Answer:

2 wholes and 5/26

Step-by-step explanation:

convert the mixed number to improper fraction

= -19/6 / -13/9

since there is 2 negatives and (-)/ (-) means your answer is positve

to divide by a fraction multiply by the reciprocal of that fraction.

19/6 x 9/13

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

19/2 x 3/13

multiply 19/2 x 3/13

= 57/26

= 2 wholes and 5/26

= 2.1923076

11/26 chance that the student plays both instruments.

First, add the amount of students that just play flute or piano:

3 + 5 = 8

Then add 8 to the amount that does not play either instrument:

8 + 7 = 15

Then do:

26 - 15 = 11

Then place 11 over the amount of people:

11/26
