Acompany had 3,000 people come try their product. 21 out of the 3,000 people had an allergic reaction. what is the percent of the people that had an allergic reaction.

number of people that had allergic reactions is 0.7%

Step-by-step explanation:

The total number of people that came to try the company's product is 3000

21 out of the 3,000 people had an allergic reaction. We want to determine how many percent of the total number of 3000 people that tried the product is 21 people that had reaction

Percentage of people that had allergic reactions = number of people that had allergic reactions / total number of people that tried the products × 100

Percentage of people that had an allergic reaction

= 21/3000× 100

= 0.007 × 100 = 0.7%

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
