We will break this down into its parts:
We know that this is a fraction where the numerator is √(-1) = i
The denominator:
4 - 3i - (2 + 5i); we put 2 + 5i in brackets because we are to subtract its quantity.
Simplifying the denominator:
4 - 3i - 2 - 5i
= 2 - 8i
Now, we write the expression in fractional form:
i / (2 - 8i)
To remove an imaginary number from the denominator, we multiply and divide by its conjugate. The conjugate of a + bi is a - bi
i(2 + 8i) / (2² - (8i)²)
= (-8 + 2i) / (4 + 64)
= -2/17 + i/34
1,925 is close to 2,000
so 2,000 x 7 = 14,000
1,925 x 7 = ?
5 x 7 = 35
20 x 7 = 140
900 x 7 = 6,300
1,000 x 7 = 7,000
so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.
Hope this helps even though a little confusing! ;D
Answer 45
Step-by-step explanation: i show my work in case
Answer:
<em>s</em> = 87.5
Step-by-step explanation:
We start with 170 + 35 - 5 = 2<em>s</em> + 25
We want to find the value of <em>s. </em>Since one side of the expression (170 + 35 - 5) isn't simplified yet, that's what we should start with.
Evaluate: 170+ 35 - 5
170 + 35 - 5 = 200
Now our equation is 200 = 2<em>s</em> + 25
Solve using algebraic methods:
Start by subtracting 25 from both sides of the equation to get:
175 = 2<em>s</em>
Then, divide both sides by 2:
87.5 = <em>s</em>
The final answer you get should be <em>s </em>= 87.5
Hope this helps!
