15.9 / 100 = c / 25,250....15.9 c sections to 100 women = c to 25,250 women
cross multiply
(100)(c) = (15.9)(25,250)
100c = 401475
c = 401475/100
c = 4014.75 <===
37=30-2x
7=-2x
-3.5=x
x=-3.5
Answer:
C. 38cm
Step-by-step explanation:
hope this helps
The real part of the result is the product of the real parts of the factors and the product of the imaginary parts:
a = 15*6 - (-4)(-3) = 90 -12 = 78
_____
You can treat this the same as any other product of binomials except that i² = -1.
... (15 -4i)(6 -3i) = 15(6 -3i) -4i(6 -3i) = 15·6 -15·3i -4·6i +4·3i²
... = 90 -45i -24i +12i² = (90 -12) -69i = 78 -69i
