Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
Answer:
The red curve is the graph for given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph this function.
Properties of function:
- The given function is an exponential function of the form , where b is the base and x can be any real number.
- Here,
- It passes through the point (0,1).
- Since , the graph of function will decrease as we move from left to right.
- The domain for given function is all real numbers.
- The range for the given function is
The attached image shows the graph for the given function.
Distribute.
6 times 2x= 12x
6 times 8= 48
12x+48+3=15
12x+51=15
subtract 51 from both sides.
12x=-36
divide by 12 on each side
-3=x
If this is 2.49+1.99, then the answer is 4.48.
Answer:
conversion factor
Step-by-step explanation:
A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.
