The number of dimes that Gina has is 4.00 - (y)q.
<h3>What are word problems?</h3>
Word problems in mathematics are real-life situations that can be solved with the use of mathematical expressions (such as algebraic expressions) with the use of variables and their arithmetic operations.
Given that:
- Mona: (x)q + (y)d = 4.75 ----- (1)
- Gina: (y)q + (x)d = 4.00 ----- (2)
From equation (2), since the number of coins Mona has did not influence Gina's Coin;
The number of dimes Gina has is:
(x)d = 4.00 - (y)q

The explanation for this is one of my favorite pieces of mathematical reasoning. First, let's thing about distance; what's the shortest distance between two points? <em>A straight line</em>. If we just drew a straight line between A and B, though, we'd be missing a crucial element of the original problem: we also need to pass through a point on the line (the "river"). Here's where the mathemagic comes in.
If we take the point B and <em>reflect it over the line</em>, creating the point B' (see picture 1), we can draw a line straight from A to B' that passes through a point on the line. Notice the symmetry here; the distance from the intersection point to B' is<em> the same as its distance to B</em>. So, if we reflect that segment back up, we'll have a path to B, and because it came from of the line segment AB', we know that it's <em>the shortest possible distance that includes a point on the line</em>.
If we apply this same process to our picture, we see that the line segment AB' crosses the line at the point (1, 1)
Answer: If he gives Al 42, then he gives Bob 21 and Carl 84. Do those add up to 210? 42 + 21 + 84 = 147–that’s too small! Go bigger.
Step-by-step explanation:
So Since (D) is odd, shoot right to (E). If he gives Al 60, then he gives Bob 30 and Carl 120. Does that add up to 210? Yes, yes it does. 60 + 30 + 120 = 210.
