Answer:
Hope this helps..
Step-by-step explanation:
So when you need to divide one complex number by another, you multiply the numerator and denominator of the problem by the conjugate of the denominator. This step creates a real number in the denominator of the answer, which allows you to write the answer in the standard form of a complex number.
The negative number would most likely be -19/2
let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0
hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2

66 out of 100 (66/100) of the grid is shaded, which is 66%
Answer:
140 people
Step-by-step explanation:
We can make two ratios...
7:10
x:200
We can since 10*20 = 200, we can multiply 7 by 20 to get x.
x=7*20=140
140 people are expected to be able to curl their tongue
