Answer:
x is x≥0 x ≥ 0
Step-by-step explanation:
I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.
2x^2 + 8x = 0
2x(× + 4) = 0
2x = 0
x = 0/2 =0
x + 4 = 0
x = -4
C^2+7 would equal 88. the first equation states that C=9, so you can just plug in 9 for C
The answer should be 320 oz.
