Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

Answer:

twelve decreased by twice a number > 12 - 2x

8 times the sum of number and 4 > 8 (x + 4)

12 - 2x = 8 (x + 4)  then 12 - 2x = 8x + 32 (distributive property)

12 = 10x + 32 (add 2x to both sides)

-20 = 10x (subtract 32 from both sides)

x = -2 (divide both sides by 10)

since you are subtracting a negative you can do it this way. do 7 3/5 - 6 1/5. that leaves you with 1 2/5. so in the end you will have -1 2/5

10 + (2 x 3) {2} divided by 4 x (1/2) {3} = 2.375 (2  3/8)

Step-by-step explanation:

2 x 3 is 6 and 6 to the power of 2 is 36, and PEMDAS makes it where you divided 36 by four instead of 46 (10 + 36) divided by 4. 36 divided by 4 = 9. 10 + 9 = 19. Then 1/2 to the third power is 1/8. 19 times 1/8 = 2.375 (2  3/8)
