C = 2(3.14) x r
C = 6.28 x 10
C = 62.8 yards
Answer:
y=3x+5
Step-by-step explanation:
I think that this is what they mean...
y=mx+b
y=3x+b
y=3x+5
plug in #s
5=15+5
5=20 no
In cases like these, you simply have to multiply the choices you have for each step.
In fact, you can choose between 4 different crusts. For each of these crusts you can choose 4 different sauces. This means that there are 
choices at this point. In fact, if we call the crust options 1,2,3,4 and the sauce options A,B,C,D, the 16 possible combinations are
From here, you keep going multiplying the number of options for each step, for a total of
If the scholarship pays 75% of her classes cost, that means that she has to pay the 25% remaining of the classes cost so if we calculate it as follow:
0.25 * $14,000 = $3,500
=================================================================
Another method to understand:
if the scolarship pays 75% of her classes that will be
0.75* $14,000 = $10,500
now she has to pay the remaining of the total cost and that will be
$14,000 - $10,500 = $3,500.
The answer is -3 because -3+2=-1 then -1(4)=-4
