Adetergent is manufactured using only the three ingredients a,b, and c, which are mixed in the ratio of 1: 4: 5, respectively, by weight. how many pounds of ingredient a are in 80 pound (net weight) bucket of the detergent

8 pounds

You can find the percent of ingredient A in the detergent by dividing the amount of A in the ratio (1), by the total amount in the ratio (1 + 4 + 5, which gives you ten). This gets you 1/10, which is 10% of the detergent. Since you have 80 pounds, 10% of it would be 8 pounds, but you could just multiply 80 by the fraction you got (1/10) to get 8 pounds too.

y=1/2x+1

y/1=1/2

=2y=x+1

2y-1=x

y=x

therefore=x=y

Step-by-step explanation: because we are changing subject to formula
