Dale says the ratios 3: 5 and 2: 10 are equivalent. is he correct? explain.

Dale is not correct. You can reduce the second ratio by dividing both parts by 2. Then it becomes 1 : 5, which is clearly different from 3 : 5.

step-by-step explanation:

no

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
