Answer:
On Saturday night it had sold 35 numbers of cups.
Step-by-step explanation:
On the Saturday night the ratio of the number of cones to the number of cups sold is 6 : 5 in Freshly frozen yogurt however on Sunday night the ratio of the number of cones to the number of cups is 4 : 1.
Now, if the Freshly frozen yogurt sold 42 cones on Saturday night then in the ratio of 6 : 5, it sold cups 
times the number of cones.
Therefore, on Saturday night it had sold 
numbers of cups. (Answer)
STEPS TO GET THE CORRECT ANSWER:
First write your question like this:
{ ( [9x] [-31/8] ) - ( [7x] [+13/8] ) }
2: You need to subtract 9x and 7x from (9x-31/8)-(7x+13/8) you get 2x. So now you know that the answer has 2x. Eleminate A) and D).
3: Then need to subtract -31/8 from +13/8. You get -11/2.
Turn -11/2 into a mixed number you will get -5 1/2.
4: Put 2x and -5 1/2 together and you would get 2x-5 1/2
But answer C.) is closest to 2x-5 1/2 so the answer is
ANSWER: C.) 2x-4 1/2
Two positive integers have gcd (a, b) = 15 and lcm (a, b) = 90. Those two numbers are 15 and 90 or 30 and 45.
Suppose we have 2 positive integers, a and b, then:
gcd (a, b) = the greatest common divisor = common prime factors of a and b
lcm (a, b) = the least common multiple = multiplication of the greatest common prime factors of a and b
In the given problem:
gcd (a, b) = 15
prime factorization of 15:
15 = 3 x 5
Hence,
a = 3 x 5 x ....
b = 3 x 5 x ....
lcm (a, b) = 90
prime factorization of 90:
90 = 3 x 5 x 2 x 3
Therefore the possible pairs of a and b are:
Combination 1:
a = 3 x 5 = 15
b = 3 x 5 x 2 x 3 = 90
Combination 2:
a = 3 x 5 x 2 = 30
b = 3 x 5 x 3 = 35
We can conclude the two integers are 15 and 90 or 30 and 45.

Answer: 1400
Step-by-step explanation: you add 40 and 30 then you times it by 20 because it said " what is the area of the part that's painted blue" it's trying to throw you off by having the other numbers by the window and the door.
