Answer:
Ron multiplied with the wrong number. He should have multiplied with 3/2 (the reciprocal of 2/3), which would have made the 2/3 a 1, thus isolating the r.
r = 18
Step-by-step explanation:
(2/3)(3/2)r = 12
r = 12(3/2)
r = 18
Answer:
x = 15
Step-by-step explanation:
<u>Step 1: Make an expression</u>
<em>4/6 = 10/x</em>
<em />
<u>Step 2: Cross multiply</u>
4/6 = 10/x
<em>4x = 60</em>
<em />
<u>Step 3: Divide both sides by 4</u>
4x / 4 = 60 / 4
<em>x = 15</em>
<em />
Answer: x = 15
Answer:
The second and fourth options
Step-by-step explanation:
A function is where one the inputs have only one output. In this case all we have to do is look at the x value (x,y) and see when it goes 1,2,3,4 and that means there are no repeating x and in that case each input has only one output. If you look at the other ones they have a repeating x and that means the input has two outputs and therefore it isn't a function.
