Use cross products to solve the proportion. equation 1. use cross products: (4)(12) = 3x 2. multiply: 48 = 3x 3. divide both sides by 3: = x

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

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

47 - 90 = 43

43 - 180 = x

x = 137
