4 0

Answer:

m = - 1.25

Step-by-step explanation:

20 = - 2(4m - 5) ← divide both sides by - 2

- 10 = 4m - 5 ( add 5 to both sides )

- 5 = 4m ( divide both sides by 4 )

- \frac{5}{4} = m , that is

m = - 1.25

Find two complex numbers that have a sum of 10i, a difference of -4 and a product of -29
HACTEHA [7]

Let these two numbers be z and w. Their sum is 10i, their difference is -4, and their product is -29:

z+w=10i

z-w=-4

zw=-29

Add the first two equations together to eliminate w:

(z+w)+(z-w)=10i-4\implies 2z=-4+10i\implies z=-2+5i

Then

w=10i-z\implies w=10i-(-2+5i)=2+5i

Just to confirm this is correct, check their product:

(-2+5i)(2+5i)=-4+25i^2=-4-25=-29

Pepsi [2]
The have ordered 36 blue T-shirts.
___________________

How I got it --- So, we take away 16 from 58. You get 42. 
________________________________________

So, from then, you know 36 is 6 times as many as 6, right? ( Because 6 x 6 = 36)
___________________________________________________________

So, then, you have ordered 36 blue shirts and 6 white shirts, because 36 + 6 =42.

Glad I could help, and good luck!
