Answer:
The solution for the given algebraic equation is 
Step-by-step explanation:
Given algebraic equation as :
( x - 8 ) + 1 = 2 ( 18 x - 1 )
Now solving the equation while opening the brackets
So,
× x -
× 8 + 1 = 2 × 18 x - 2
Or,
-
+ 1 = 36 x - 2
or,
- 4 + 1 = 36 x - 2
or,
- 3 = 36 x - 2
or,
- 36 x = - 2 + 3
Or,
- 36 x = 1
or,
= 1
or,
= 1
∴ 71 x = - 2
I.e x = 
Hence The solution for the given algebraic equation is
Answer
There are no tanks with less than 30 fish, so the first two groups ( 20-24) and (25-29) aren't used.
There are 3 tanks with 30-34 fish.
There are 3 tanks with 35-39 fish.
There are 3 tanks with 40-44 fish.
There are 1 tanks with 45-49 fish.
Now drag the bars for each group to the number of tanks.

Answer:
x=-2
Step-by-step explanation:
-4x – 6(3x + 4) = -4 + 8(1 - x)
Distribute
-4x – 18x -24 = -4 + 8 -8x
Combine like terms
-22x -24 = 4-8x
Add 22x to each side
-22x+22x -24 = 4-8x+22x
-24 =4+14x
Subtract 4 from each side
-24-4 = 4+14x-4
-28 = 14x
Divide each side by 14
-28/14 =14/14
-2 =x
Company A : 15h + 20
Company B : 5h + 40
when would company B be cheaper....
15h + 20 > 5h + 40 ...put the less then sign towards Company B, then solve
15h - 5h > 40 - 20
10h > 20
h > 20/10
h > 2
Company B would be cheaper when the hours (h) are greater then 2
