Answer:
x =7
Step-by-step explanation:
2x+6 = 20
To solve this equation, you first need to subtract 6 from each side
2x+6-6 = 20-6
2x = 14
Then divide each side by 2
2x/2 = 14/2
x = 7

Answer:
-3/5
-1/2
-0.4
0.6
4/5
Step-by-step explanation:
For this question I converted the fractions to decimals.
-3/5 = -0.6
-1/2 = -0.5
4/5 = 0.8
Start off with the negatives, as they are the lowest numbers. <em>The further they are from zero the lower they get.</em>
-0.6 (-3/5)
-0.5 (-1/2)
-0.4
Now there are only <em>2</em> positive numbers, so order them.
0.6
0.8 (4/5)
Put it all together:
-3/5
-1/2
-0.4
0.6
4/5
Each pound cost $3.32
p pounds would cost = p*3.32 = 3.32p
Total cost C = $3.32p
I hope this explains it.
