Answer: x=2.5
Step-by-step explanation:
First we need to set up and equation
10= 60 - 20x
where x is the amount the cookies cost
subtract 60 from both sides
-50=- 20x
now divide each side by 20 so hat we can isolate the x
-50/-20= x
x= 2.5
now to check just multiply it by 20 then subtract from 60.
2.5 x 10= 50
60-50=10
Answer:
Step-by-step explanation:
x+x+9=65
2x=56
x=28
28,37
4x^2+12x+7x
4x^2+19x
Was it meant to equal something or are you just simplifying the equation?
Answer:
Union and Intersection
Step-by-step explanation:
We know that the algebra of sets define the properties and laws of the sets.
The basic operations of sets are,
Union, Intersection, Complement of a set and Equality of sets.
Since, the operations addition, subtraction, multiplication and division are the basic arithmetic operations of numbers.
i.e. they are not in the algebra of sets.
So, we get that out of the given options, the operations in algebra of sets are Union and Intersection.
Answer:
a' > a
Step-by-step explanation:
A larger value for a will stretch the exponential in the y direction. A larger value for b will stretch it in the x direction.
