Answer: x = 28
Step-by-step explanation:
Let's solve your equation step by step!
3/8x + 15/2 = 18
Step 1: Subtract 15/2 from both sides.
3/8x + 15/2 - 15/2 = 18 - 15/2
3/8x = 21/2
Step 2: Multiply both sides by 8/3
(8/3) * (3/8x) = (8/3) * (21/2)
Step 3. Calculate
x = 28
Answer:
Option B.
Step-by-step explanation:
We need to express 505 kL in L.
Here, kL means kiloliter and L means liter.
We know that
1 kL = 1000 L
Using this conversion we can easily convert 505 kL in L.
Multiply both sides by 505.
505 × 1 kL = 505 × 1000 L
505 kL = 505,000 L
The value of 505 kL can be expressed as 505,000 L.
Therefore, the correct option is B.
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-
