Answer:
here is answer
Step-by-step explanation:
n(AUB) = n(A) + n(B) - n(AnB )
= 240 + 160 - n(A n B)
= 400 - n(AnB )
Since n(AnB) 20, so n(AUB) S 400
But n(U) = 360, so n(A U B)* 360
.. the maximum value of n(AUB) = 360.
When n(A U B) is maximum, n(AnB) will be minimum.
.. min. value of n(An B)
= n(A) + n(B) - Max, value of n(AUB)
= 240 - 160 - 360 = 40
Again, n(
A B) will be maximum when B C A.
..the max. value of n(
A B) = n(B) = 160
Answer: The number of small cookies sold = 75
Step-by-step explanation:
GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.
Let 7x be the number of cookies and 5x be the number of small cookies. (i)
They sold 30 more large cookies than small cookies.
i.e. 
(Using (i))
Thus, the number of small cookies sold = 5 (15)=75 (Using (i))
Hence, the number of small cookies sold = 75
Answer:
A.)z+y+x
Step-by-step explanation:
Addition (+) is a commutative operator.
Answer:
30/7
Step-by-step explanation:
Distribute:
-2x-26+9x=4
Combine like terms:
7x-26=4
Add 26.
7x=30
Divide by 7:
x=30/7.
Hope this helps :D
A triangle's angles will always equal up to 180. Since you already have to of the angles, you will add them up together. 30+20=50. Then, you take 180 and subtract it by the sum of the two previous angles. 180-50=130. Now you know the last angle is 130. You also know that the missing angle is also 130. The reason for that is because the two angles are the exact same if you look at it.
