Answer: 33 tulips bloomed / 66 tulips did not bloom
Step-by-step explanation:
<h2>Given:</h2>
Total number of tulips = 99
Total number of tulips bloomed = 3/9 of total
<h2>Solve:</h2>
Step One: Find the number of tulips that bloomed
99 × (3/9) = 99 × (1/3) = 33 tulips
Step Two: Find the number of tulips that did not bloom
99 - 33 = 66 tulips
Hope this helps!! :)

Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.
