c i think (answer needs to be 20 characters long)
<span>We can represent the number of pies she makes to be x.
We also need to add $30 to the equation to take the baking supply cost into consideration.
The Cost can be represented by C.
C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies!
If we look at just the cost when she doesn't sell any pies, we can say x = 0
That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies.
This makes sense since the baking supplies were $30.
Are you with me so far?</span>

Step-by-step explanation:
Answer:
Katrina got 86 in her test
Step-by-step explanation:
given
mean = 80
standard deviation = 3
z-score = 2
Let score of Katrina = x
Recall z-score is calculated by
z-score = (x-mean) / standard deviation
substitute values and solve for x
2 = (x-80)/3
x-80=6
x = 86
Answer:
32
Step-by-step explanation:
first simplify the exponent
4^2 = 16
so u would get
2 + 16 / 2 • 5 - 10
then divide and multiply to get
2 + 8 • 5 - 10
2 + 40 - 10
then add and subtract
42 - 10 = 32
