Step-by-step explanation:
1,239 + 8,568= 9,807 ≈ 10000
In this complex number, assuming that the equation actually is <span>18- √-25</span>, the real part is already simplified. However, the imaginary part can be simplified by taking out "i" from the root using the relation i = <span>√-1. This is done below:
18 - </span><span>√-25
18 - </span>√(-1)(25)
18 - 5i
From the choices, the correct answer is 18 - 5i.
Answer:
x = -2
Step-by-step explanation:
1. Evaluate the function when x=-2.
This means to plug in -2 anywhere you see x in the equation.
3(-2)+4
2. Simplify and solve.
-6+4
x = -2
Answer:
325 boys
Step-by-step explanation:
The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.
Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school
Hope this helped, from what i recall, i think this is how you solve the problem.
