📝 Answered - Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00. a. Write a system of inequalities that represents the number of quarters, $q$, and the number of dimes, $d$, that Mai could have. b. Is it possible that Mai has each of the following combinations of coins? If so, explain or show how you know. If not, state which constraint—the amount of money or the number of coins—it does not meet. (From Unit 2, Lesson 25.) i. 3 quarters and 12 dimes ii. 4 quarters and 10 dimes iii. 2 quarters and 5 dimes

📝 Answered - Solve the equation and check your solution: [tex]x=\frac{x-5}{2}=\frac{4 x}{3}[/tex]

📝 Answered - $3 x-\frac{2 x+6}{3}=16-\frac{x+2}{2}$

📝 Answered - A quarterback throws a football to a teammate. The football is 6.5 ft above the ground when it leaves the quarterback's hand. His teammate catches it 3.5 s later, at a height above the ground of 5 ft. Projectile motion formula [tex]\begin{array}{l} h(t)=-16 t^2+v t+h_0 \\ h_0=6.5 \\ v=? \\ h=5 \text { when } t=3.5 \end{array}[/tex] Determine the value of [tex]v[/tex], rounded to the nearest whole number. [tex]v \approx[/tex] $\square$
