Minus 1 on both sides
Divide by 3 on both sides
C 5 > 7/3
Now, to change a decimal to fraction, we use "as many zeros on the denominator as there are decimals, and lose the dot", so let's do so.
-83.2 has only 1 decimal, so we'll use one zero,
now if we divide 416 by 5, we end up with a quotient of 83, and a remainder of 1,
The answer to your question is that she can make 17 trains of 10 cubes so the answer is 17

Answer:</h3>
18
<h3>
Step-by-step explanation:</h3>
Put 3 where x is, then do the arithmetic.
... f(x) = x(5x -9)
... f(3) = 3(5·3 -9) = 3(15 -9) = 3·6
... f(3) = 18

Your calculator can do this, too.
Answer:
D.
Step-by-step explanation:
let's call A the number of copies sold of newspaper A and B the number of copies sold of newspaper B.
So, we can formulate the following equations from the sentence: a certain store sold copies of 256 Newspaper A for $1.00 each and copies of Newspaper B for $1.25 each as:
A + B = 256 (1)
1A + 1.25 B = Total Revenue (2)
Then, r and p are equal to:
(3)
(4)
Isolating A from (4) and B from (1), we get:
(5)
(6)
Finally, replacing (5) and (6) in (3), we get:
