Answer:
10 / 12
simplified:
5/6
since 5 is a prime number, we can't simplify this ratio any further
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
Answer:
(3 , 8)
Step-by-step explanation:
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
Answer:
the college student has:
8 quarters
20 dimes
Answer:

Step-by-step explanation:
The only thing important in this question in the original equation is the slope, which is 3, the multiplyer for x. To find the opposite slope follow the steps below.
The first step is to make the original slope into a fraction.

Then flip the numerator and denominator.

Now multiply this value by -1.

There is the opposite slope of 3.
