In order to solve this equation you must first simplify, then you re-range the terms, then solve.

12(x + -360) = 120

12(-360 + x) = 120

(-360 \times 12 + x \times 12) = 120

(-4320 + 12x) = 120

+ 4320+ 4320

12x = 4440

4440 \div 12 = 370

x = 370

Which means your answer is "x=370."

Hope this helps.

Which expressions is equivalent to 2r+(t+r)
azamat

Answer:

t+3r

Step-by-step explanation:

This is a one step solution

All you do is add like terms

In this case the only like terms are the varibles r

2r+(t+r)

so if you add all of the rs together there would be 3rs

So the rest of the problem would continue as normal while bringing the 3r to the end

t+3r

andrew-mc [135]

Answer:

100

Step-by-step explanation:

Mixed candy question... Skittles jar... to be filled with Jelly beans.

Let's first calculate the volume of the jar.  We'll assume it's a regular cylindrical prism jar, unlike the one on the photo which is narrower on top.

V = π * r² * h = π * (3.5)² * 11.5 = 140.875 π = 442.6 cubic cm

Now, we don't have the precise measurement of a jelly bean, but we know it's roughly 2-3 cubic cm.  The precision isn't needed to answer this question, just to have a rough idea... it's no 300 cu cm per jelly bean.

So, let's assume a 3 cu cm per jelly bean (2 cu cm wouldn't the final answer)....

442.6 / 3 = 147.5 jelly beans, approximately.

So, can they fit 100,000?  No

Can we fit 10,000 in there?  No

Can we fit 100?  Yes.

Can we fit 1?  Certainly

The most reasonable lower-limit would then be 100.

   y - y₁ = m(x - x₁)
y - (-1) = 4[x - (-3)]
   y + 1 = 4(x + 3)
   y + 1 = 4(x) + 4(3)
   y + 1 = 4x + 12
       - 1           - 1
         y = 4x + 11

The answer is B.
