<span>So...
We distribute so that...
7 * 2 = 14
7 * i = 7i
then
-3i * 2 = -6i
-3i * -i = 3i?
</span><span>then combine like terms...
7i - 6i + 3i = 4i
so 14 + 4i?</span>
Answer:
Step-by-step explanation:
3/7 * 11/4=1.17857142857
Answer: 3/40
Step-by-step explanation:
0.5 = 1/2
0.15 = 3/20
1/2 * 3/20
1 * 3 = 3
2 * 20 = 40
3/40 is the simplest form, since 3 and 40 cannot both be divided by the same number.
If x is inversely proportional to y, then:
x=k/y.
When y=2, x=3.
3=k/2, therefore k=6.
So, x=k/y is in fact x=6/y.
When x=9:
9=6/y
9y=6
y=6/9=2/3.

You can convert the mixed numbers to solve it easier! :)
