Answer:
x = 1/3
Step-by-step explanation:
3(x – 1) – 2(2x + 1) = 8(x – 1)
Distribute
3x-3 -4x-2 = 8x-8
Combine like terms
-x-5 = 8x-8
Add x to each side
-x+x-5 =8x+x -8
-5 = 9x-8
Add 8 to each side
-5+8 = 9x-8+8
3 = 9x
Divide by 9
3/9 =9x/9
1/3 =x

160% of 19 is 30.4
Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.
------
0.9% of 54 is 0.486
Convert 0.9% in a decimal: 0.9%/100 = 0.009
Multiply the decimal by 54: 0.009 × 54 = 0.486 <-- our answer.
-------
15% of 376 is 56.4
Convert the percentage into a decimal: 15%/100 = 0.15
Multiply the decimal by 376: 0.15 × 376 = 56.4 <-- our answer.
1 3/8 the denominators have to be the same so you multiply 2 to 3/4 to get 6/8 btw they are common denominators so you can easily multiply two and the you add the to get 11/8 and if you simplify it you'll get 1 3/8
