Answer:
$8
Step-by-step explanation:
It says P = per ball (which will be a number, n, for balls times the fixed price) plus a set entrance fee. So we find that the price per ball is $0.80, so 10 balls cost $8.
Answer:
Step-by-step explanation:
Simplifying
3y + -2y = 1
Combine like terms: 3y + -2y = 1y
1y = 1
Solving
1y = 1
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '1'.
y = 1
Simplifying
y = 1
Answer:
1,700
Step-by-step explanation:
The computation of the initial value of the computer is shown below:
Let us assume the value of a certain computer in the first year is X
In the second year, it is 
In the third year, it is 
In the fourth year, it is 
Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

So, X = 1,700
Hence, the initial value of the computer is 1,700
I would go with A, but I'm not positive.
First you make them fractions that have the same denominator. 12 can be the denominator, because 6 5/12 already has that denominator and to get 2 2/3 to have a denominator of 12, you multiply the numerator and denominator by 4 (3•4=12, but you have to do the same thing to the top and bottom of the fraction). You then have the equation
6 5/12- 2 8/12. Since you cant subtract 8/12 from 5/12, you turn the numbers into improper fractions, which would be
77/12 - 32/12. You subtract them and get 45/12. You then have to simplify it again, 12 can go into 45, 3 times and you would have 3 and 9/12. 9/12 can be simplified down to 3/4. So the answer would be 3 3/4.
