Direct Variation<span>. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).</span>
The answer would be c which is equal to x or t-x equals 4 or the answer
Answer:
L = 3t + 6
108 = L + t
Step-by-step explanation:
first, define the variables:
L = # of CDs sold last week
t = # of CDs sold this week
then, let's write what the words of problem tells us in numbers:
"Last week (L), she sold 6 more (+ 6) than 3 times the number of CDs she sold this week (3t)
L = 3t + 6
"She sold a total of 108 CDs over 2 weeks (L + t)
108 = L + t
If Carrie has a string 9 inches long, what she will cut the piece into is mathematically given as
X=2.25pcs
<h3>What is the number of pieces?</h3>
Generally, the equation for the number of pieces is mathematically given as
X=Total number *ratio
Therefore
X=9*1/4
X=2.25
In conclusion, If Carrie has a string 9 inches long, she will get 2.25 pics at a 1/4 ratio
