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
The surface area is the sum of the area of the six sides...
A=2(xy+xz+yz)
A=2(8*3+8*5+3*5)
A=2(24+40+15)
A=2(79)
A=158 cm^2
(a) 24
(b) 0.037 ft^3
(c) 0.888
There are 15 novelists and 9 poets. This is a ratio of 5 to 3 and adds up to 24 people
Answer:
The infant should be given 700 mg of Claforan every 8 hours.
Step-by-step explanation:
This question involves proportional measures, and asks how many mg of Claforan the infant should be given every 8 hours.
For each kg, the infant should be given 50 mg of Clarofan. The infant weighs 14 kg, so he should be given 14*50 = 700 mg of Claforan every 8 hours.
