This is a ratio problem
6 / 800 = 9 / n (can say as 6 is to 800g as 9 is to n grams)
6n = 800(9) --- by multiplying means and extremes
n = 7200 / 6 divide by 6 to isolate n
n = 1200g
plug in to check 6 / 800 = 0.0075 9 / 1200 = 0.0075
Answer:
Step-by-step explanation:
<u>Use the ratio to solve:</u>
<u>Cross multiply and solve for x:</u>
- 4.5x = 4.04*47.25
- 4.5x = 190.89
- x = 190.89/4.5
- x = 42.42
The answer is $42.42
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
