Answer:

m = 35

Step-by-step explanation:

∵ m ∝ xy

∴ m = kxy

∵ m = 7 when x = 3 and y = 15

∴ 7 = k (3) (15)

∴ 7 = 45k ⇒ ∴ k = 7/45

∴ m = 7/45 xy

∵ x = 25 and y = 9

∴ m = (7/45) (25)(9) = 35

Could someone help please

Answer: B

<u>Step-by-step explanation:</u>

There are 26 letters in the alphabet.  D is the 4th letter, so there are 26 - 4 = 22 letters after D.

\frac{22}{26} ÷ \frac{2}{2} = \frac{11}{13}

- 1/3 - (-1/2) what’s the answer? Someone please help!
Natasha_Volkova [10]

Answer:

1/6

Step-by-step explanation:

So we are subtracting a negative which is the same as adding.  Our equation becomes -1/3+1/2.  To add fractions we need a common denominator (the denominator of a fraction is the number on the bottom)  To fine the least common denominator we need to find the lowest number that both 3 and 2 go into which is 6.  Then we will multiply each fraction by the number that will give us 6 for a denominator which is 2 for -1/3 and 3 for 1/2.  So -1/3 times 2 is -2/6 and 1/2 times 3 is 3/6.  Our equation is now -2/6+3/6.  Now we will add the numerators ( the numerator is the number on the top of the fraction) and the denominators stay the same when adding or subtraction fractions -2/6+3/6=1/6

I hope this helps and please let me know if there is anything you are confused about or is still unclear, I will be happy to help!
