Answer:
Quadratic function
Step-by-step explanation:
Answer:
2 science fiction and 5 mystery
Step-by-step explanation:
First, we will set up a system of equations.
x (science fiction) y (mystery)
x + y = 7 This is the total books bought.
7x + 9y = 59 The amount of each set to the total cost.
Now we solve.
(-7)x + y = 7 equals
-7x - 7y = -49
added to
7x + 9y = 59
this equals
2y = 10
y = 5
Now we know one. We can plug it in to find the other value.
x + 5 = 7
x = 2
21/35 = x/100
cross multiply
2100=35x
x = 60
Answer:
7.5 pounds.
Step-by-step explanation:
the answer is 7.5 ponds because if each slider has 2 oz. then we can find the total number of oz. needed by multiplying by 60. This gets 120 oz that Scarlett needs in total. Since there are 16oz in a pound we divide 120 by 16 to find the number of pounds needed.
