Sidney originally had c cups of Greek yogurt. He used 1.75 cups to make a salad dressing and now he has 5.5 cups left over. Which equation can be used to determine the value of c? A.1.75c=5.5
B. c/1.75=5.5
C. c-1.75=5.5
D. 1.75+c-5.5

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

i think the answer is d im not sure
