Simplify the expression-3÷(-2/5)​
BARSIC [14]

Answer:

15/2 or 7.5

Step-by-step explanation:

-3÷ (-2/5)

The reciprocal of -2/5 is -5/2

So we multiply -3 into the reciprocal of the fraction and we can get the same answer

Therefore,

-3÷(-2/5)

= -3x -5/2

= (-5x-3)/2

(Two negatives become a positive)

= 15/2 in fraction form

And 7.5 in decimal form

How do I solve this?
snow_tiger [21]

Answer:

B

Step-by-step explanation:

it means we assume that the progression between 2 interval points is linear (a straight line from the begin of the interval to the end of the interval).

so, a length of 9.5 in falls into the interval [9, 11].

in this interval we see that the change rate is (21 - 11)/(11 - 9) = 10/2 = 5/1

that means for every inch longer we expect 5 oz more.

the line equation there is

y = 5x + b

11 = 5×9 + b

11 = 45 + b

-34 = b

so, the line is

y = 5x - 34

for x = 9.5

y = 5×9.5 - 34 = 47.5 - 34 = 13.5 oz

B is with 13.4 the closest right answer.
