Can someone help meWhat is the missing numerator?

Answer:
d 2
Step-by-step explanation:
x/7 +13/14 = 17/14
double the first one so all the denominators are the same
2x/14+13/14=17/14
then subtract the second fraction from the thrid
2x/14=4/14
then we can divide by two so we are back to 7 as the demoninator
x/7=2/7
X/7 + 13/14 = 1(3/14)
Convert the mix fraction into improper fraction:
(14 x 1) + 3 = 17 /14
X has to equal the difference between 13 and 17 which is 4
Remember since the lowest common denominator is 14 you would have to multiply x/7 by 2 on top and bottom and make sure that the x value is equal to 4
So ...
(2/7) + (13/14)
(4/14) + (13/14)
Add the number and keep the denominator the same
= 17/14 or 1(3/14)
Therefore the missing number is 2.
I hope this doesn’t sound too confusing :)

Answer:
let the width be 'x'
length = 2x
Area = 72 in square
(2x)(x)= 72
2x^2=72
x^2=36
x=6
perimeter = 2(l+b)
=2(2x+x)
=2(3x)
=2(3*6)
=2(18)
=36 inches
therefore the answer is option D

Answer:
jamie
Step-by-step explanation:
jamie received the most because once you divide them this is what you get
jamie: 40/4 (10/per hour)
jasmine: 56/7 (8/per hour)
Kevin: 54/6 (9/per hour)
Addition, distributive, and multiplication property
9e + 4 = 14 + 8e
9e = 10 + 8e (Subtract 4 from both sides)
e = 10 (Subtract 8e from both sides)
