Solve for X with A and B

9 and 3

Step-by-step explanation:

10/15=6/(2x-9)

90=10(2x-9)

9=2x-9

x=9

18-8=10

10/(4x+3)=8/12

120=8(4x+3)

30=8x+6

x=3

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

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
