0
Step-by-step explanation:
Answer:
X=-5
Step-by-step explanation:
Since anything divided by one is still that number, then (x-7)/1 becomes x-7. So our equation now looks like:
(X-19)/2=(x-7).
Multiplying both sides by 2, we get
X-19=2x-14
Adding 19 to both sides:
X=2x+5
Subtract 2x from both sides:
-x=5
Multiplying both sides by -1, we get:
X=-5
Answer:
the answere is 3.6
Step-by-step explanation: it would be the third one
Since the diver is 19 metres below the surface of the water, then he will need to travel 19 metres to reach the surface.
Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
