Answer:
the number I would to divide the numerator and denominator is 5/5
Answer:
Rational
Step-by-step explanation:
This can be reduced to a ratio of 1/2. Numbers that can be expressed as ratios are rational.
Answer:
10 -16 i
Step-by-step explanation:
given,
(3+ 4 i) + (7 − 20 i)
for the given complex number
if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.
now
= (3+ 4 i) + (7 − 20 i)
= (3 + 7) + (4+(-20)) i
= 10 + (-16) i
= 10 -16 i
so, the given answer will be 10 -16 i
The correct statements are options C and option D.

<h3 /><h3>What is inequality?</h3>
The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than.
The inequality is -3(2x - 5) < 5(2 - x)
At first, simplify each side
-3(2x - 5) = -3(2x) + -3(-5)
Remember (-)(-) = (+)
-3(2x - 5) = - 6x + 15
5(2 - x) = 5(2) + 5(-x)
Remember (+)(-) = (-)
5(2 - x) = 10 - 5x
- 6x + 15 < 10 - 5x
Subtract 15 from both sides
- 6x < -5 - 5x
Add 5x to both sides
- x < - 5
Remember the coefficient of x is negative, then when you divide both sides by it you must reverse the sign of inequality
The coefficient of x is -1
Divide both sides by -1
x > 5
Therefore the correct statements are options C and option D.
