Determine the quotient of 3 over 7 divided by 2 over 3 . 6 over 21
1 over 2
9 over 14
1 and 5 over 9

9 over 14 Is the answer

9 over 14

Step-by-step explanation:

Lets put this into math:

3 over 7 = 3/7

2 over 3 = 2/3

3 over 7 divided by 2 over 3: (3/7)/(2/3)

Remember that you can multiply by the reciprocal of the denominator, so:

(3/7) * (3/2)

The easiest way to solve this is to go step by step in the numerator.

So first, 3 * 3 = 9

This gives:

9/7 * 1/2

Now divide the numberator by the 2 (multiply by 1/2)

9 * 1/2 = 4.5

This gives 4.5/7

This not one of the options, but by scaling it up you see that 4.5/7 = 9/14

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
