Answer:
The answer to this is any number > 5 will work.
Step-by-step explanation:
Since 20 > 5 + 3x is the inequality, we can then solve for x and see what we have.
20 > 5 + 3x
15 > 3x
5 > x

Answer: 0.4%
Step-by-step explanation:
Total number of people 9000, divide the number of allergic reactions 36 by 9000.
36/9000=0.004
Now multiply 0.004 x 100 to reveal percent allergic reaction
0.004 x 100 = 0.4%
0.4% had allergic reactions
Answer:
The congruent side length is 6. The third side length is 3.
Step-by-step explanation:
- You find the square root by multiplying two of the same numbers to equal 36 which the answer is equal to 6.
- Then you find the cube root of 27 by multiplying three of the same numbers together to equal 27 which is equal to 3.
