Answer:
LCM is 30.
Step-by-step explanation:
She forgot that they both can multiply into 30. She listed all their multiples and their LCM is 30. Not 60. That's her error.

Let's get this equation into a usable format, which is
<em>y=mx+b</em><em /> (where m is the slope and b is the y-intercept), before graphing.
First, we move our x terms onto one side, so that the y terms are on one side, and the x terms on another side. Keep in mind that this will negate (multiply by -1) the x term we move.
<em>2y = -5x - 10</em>
Then we isolate y. We'll do this by dividing by 2.
<em>2y/2 = -5/2x - 10/2</em>
y = -5/2x - 5We now have the equation in y=mx+b format. We can now graph (it should look something like the one below).
Slope: -5/2
Y-Intercept: -5:)
Answer:
2 periods
Step-by-step explanation:
Simple interest is compounded one time, usually annually, although it could be less time or longer. Thus I answer 2 periods. If your choices include 2 years, that is most likely the answer.
To find the answer,
$10,000 x .03 = $300.
$600 / $300 = 2 periods.
Hope this helps.
Good luck
The surface area of a cylinder is given by A = 2πrh + 2πr^2. You're given the radius, r = x+2, and the height, h = x + 5. Plug them in and you're done.
