The statement "y varies directly as x," means that when x increases, y increases by the same factor. In other words, y and x always have the same ratio: y/x =K
it can be written as ---> y=kx
then put in the values to get a common ratio
k= y/x
k1= 11/7
k2= 13/8
therefore, there's no common ratio in the given table
Answer:
Alicia ran 12 miles.
Step-by-step explanation:
They said that Nara ran 14 miles and she had ran 2 more than Alicia, so that would be 14 - 2 which is 12.
Answer:
Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:
X + Y = 10
X + Z = 20
+ Y + Z = 24
----------------
2X + 2Y + 2Z = 54
Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.
Step-by-step explanation:
hopefully this helps
20-2.3=17.7 what don't you understand?
<span>20-2= 18 </span>
<span>18-.3=17.7
</span><span>its reasonable because if you do the calculation, 17.7 is the answer
