-x/y is equivalent to x/-y according to the division rule a/b*d/c=a/b*c/d.
<h3>Describe division.</h3>
In division, a number is divided, which is an easy operation. In mathematics, division is the division of a sum into equal parts. A group of 20 people, for instance, could be divided into four groups of 5, five groups of 4, and so on. Division's opposite is multiplication. If 3 groups of 4 add up to 12, then 4 are in each group when 12 is divided into 3 equal groups.
According to the division rule a/b/c/d=a/b*d/c,
=1/(y/-x)
=1*-x/y
=-x/y
-x/y is equivalent to x/-y according to the division rule a/b÷c/d=a/b*d/c.

Simplified expression for total amount spent is 10(2.05 + m)
Step-by-step explanation:
- Step 1: Write expression for expense on joining cooking club for m months.
Expense = 8.50 + 6.25 × m
- Step 2: Write expression for expense on joining movie club for m months.
Expense = 12 + 3.75 × m
- Step 3: Calculate the total amount spent on both clubs
Total Amount = 8.50 + 6.25m + 12 + 3.75m = 20.5 + 10m = 10(2.05 + m)
Answer:
The answer is C. 904.32 in^3.
Step-by-step explanation:
To find the volume of a sphere with a radius of 6 in, start by using the formula for a sphere, which is V=. However, for this formula instead of using (), 3.14 will be used.
Now, plug the radius into the formula, and solve for V.
Finally, the answer will be 904.32 in^3.
3.4+0.5y +1.1=-4.5
3.4+1.1+0.5y= -4.5
4.5+0.5y=-4.5
move 4.5 to the other side
sign changes from +4.5 to -4.5
4.5-4.5+0.5y= -4.5-4.5
0.5y= -4.5-4.5
0.5y=-9
divide both sides by 0.5
0.5y/0.5= -9/0.5
Answer: y= -18
