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

No. If you divide 8 and 10 by 2 you get 4/5 not 2/5
Going by the formula, Half-Life = ln(.5) / k
Half-Life = .693147 / .1205
Half-Life = 5.75 days and rounded to nearest tenth,
Half-Life = 5.8 days

Answer:
x = -3
Step-by-step explanation:
7x - 3 = -24 (Given)
7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)
7x = -21 (Simplified)
7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)
x = -3 (Simplified)
Therefore, x = -3.
