Answer:
Problem:
Consider a rectangle such that the length of the rectangle is 12 more than thrice its width. Find a formula for the length in terms of its width. Take width as 'x'.
Step-by-step explanation:
Consider a rectangle such that the length of the rectangle is 12 more than thrice its width. Find a formula for the length in terms of its width.
Let the width be 'x'.
Therefore, as per question, length is 12 more than thrice the width.
Thrice the width means
. 12 more means adding 12 to the result.
Therefore, the length of the rectangle is 
So, the above question expresses the length of the rectangle as
which is the required answer.
Answer:
a. $36
b. $336
Step-by-step explanation:
The simple interest on a amount is:
A=P(1+rt)
A is the amount after interest, P is the amount before interest, r is the rate of interest and t is the time in years.
a.
We can use the formula:
The interest earned is the amount after interest minus the original amount before interest:
$36 of interest was earned
b.
The balance of the account is $336 worked out in a
Answer:
v=3w
Step-by-step explanation:
v∝w
v=kw
24=8k
k=24/8 = 3
equation connecting v and w is
v=3w
Y= 2x + 9
The slope is 6/3 which is simplified to 2. The intercept is 9.
