First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
Answer:
1/2
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
its 5:3 to
40:x
so 40/5=8
multiply 3*8 to get 24
we have the function
y=f(x)=x^2
the domain is all real numbers -------> interval (-∞, +∞)
the vertex of the vertical parabola is the origin (0,0)
the parabola opens upward
the vertex is a minimum
so
the range is the interval [0, ∞)
75: 1, 3, 5, 15, 25, 75
90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
GCF(75, 90) = 1, 3, 5, 15
1 × 3 × 5 × 15
3 × 75
225
