Answer:
Susan is 3 years and Debbie is 8 years old. after 2 years Susan will be 5 Years and Debbie will be 10 years old
Step-by-step explanation:
let the present age of Susan be x years then Debbie is x+5 years
in 2 years
x +2 = x+5+2/2
x+2=x+7/2
2x +4 = x+7
x=3
I think it would be 9, but the graph seems a bit unclear so I’m really sorry if that doesn’t help..
7+7+7=21 is the same as saying 7 times 3+
=21
For proportionality constant problems, set up the equation as,
,
Where x and y are the two variables you are comparing and <em>K </em>is the proportionality constant. If we take <em>Caramel Corn </em>values as x and <em>Cheddar Corn </em>values as y, and then solve for <em>K </em>for each ratio lines, we will get the same answer. Let's check.
,
, and
.
Hence, the proportionality constant, in this case <em>K,</em> is equal to
or 1.5. First answer choice is correct.
ANSWER: 1.5
Answer:
-19/9
Step-by-step explanation:
First, you would plug in the numbers for y and r. Therefore, your equation should now be 5 = 9x + 24. Now you would put like terms on the same side. It now then look like -19 = 9x. You divide by 9 to get the x by itself. The answer should be x = -19/9.
