2/5÷1/6 = 2/5 times 6/1 = 12/5, 12÷2 is 6, 5 ÷ 5 is 1, so it's 2/1.
There is a simple rule in multiplication, maybe you don't know it :
<h2>A/B ÷ C/D = A/B × D/C</h2>
So 32 1/4 ÷ 1/8 = 32 1/4 × 8
Let
, so that
, and
, or
.
So the ODE is
This ODE is separable, so you can write
and integrating both sides yields
Replace
and you end up with
Answer:
(-2, 0)
Step-by-step explanation:
Use elimination: add the two systems. Because the left is equal to right, you are adding the same thing and it's legal.
-x+3y=2
+ (x+y=-2)
Add each term
-x+x + 3y+y = 2+ -2
4y=0
y=0
x+y=-2
x+0=-2
x=-2
Answer: $175
