Answer:
x = 5
Step-by-step explanation:
6 + 8(x - 1) = 2(3x + 4)
We evaluate the numbers in the brackets first.
(8 × x = 8x, 8 × 1 = 8, 2 × 3x = 6x, 2 × 4 = 8)
6 + 8x - 8 = 6x + 8
The left hand side of the equation is not exactly simplified, so we will evaluate it further first.
(6 - 8 = -2)
8x - 2 = 6x + 8
Now we can start shifting the x and the numbers separately.
Note that when pushing 6x from the right side to the left side, it needs to change to a negative 6x and vice versa for -2 turning into +2.
8x - 6x = 8 + 2
Further evaluation
2x = 10
Now we can simply find x.
Note that for this, ×2 becomes ÷2 when it shifts from the left side to the right side of the equation.
x = 10 ÷ 2
Evaluate.
x = 5
It is 60 times greater than a second.
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
Answer:
$64
Step-by-step explanation:
Remaining money = 1 - fraction spent
Remaining money = 1 - (1/4 + 1/8)
Remaining Money = 1 - 3/8
Remaining Money = 5/8
$40 = 5/8 of Starting amount
Starting amount = $40 * 8/5
Starting amount = $64
