Answer:
see the explaination
Step-by-step explanation:
let x be 3:3:5
3x:3x:5x
3x is splice cookies
3x is snickerdoodle cookies
5x is no bake cookies
where 5x is equal to 45
x is equal to 45÷5=9
so x is equal to 9
now,
3x = 3×9=27
3x = 3×9=27
5x = 45 (given)
now add all, total cookies =27+27+45
=99 cookies
so there are total 99 cookies in a cookie mix
Answer:
28%
Step-by-step explanation:
78th percentile means 78% scored less than/equal to you.
100 - 78 = 22%
Hello! :)

9 = (3/8)y
Solve for y.
Isolate y by dividing both sides by 3/8, or multiplying by its reciprocal (8/3)
9 · (8/3) = (3/8)y · (8/3)
72 / 3 = y
y = 24
Putting the same common denominator would be 30. & the numerator for 1/6 would be 5, while the numerator for 3/5 would be 18. & if you subtract 5-18 you can't really do that so just switch it up (18-5) & you'd get -13 & the common denominator is 30, so in that case -13/30
