Answer:

d = 2.75 or 11/4

Step-by-step explanation:

15 = 5 + 4(2d - 3)

15 = 5 + 8d - 12

15 = 8d - 7

+7 + 7

22 = 8d

22/8 = d

2.75 = d

Check:

15 = 5 + 4(2(2.75) - 3)

2. Find the simple interest. P=$90300, R=8.7%, T=2

ZanzabumX [31]

Answer:

$15,712.20

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

8.7%/100 = 0.087

A = P(1 + rt)

A = $90,300(1 + 0.087 * 2) ( * = multiplication)

I = $106,012.20 - $90,300= $15,712.20

Which you should get $15,712.20

Hope this helps!

Simplify. 1/4n-1/2 / n/6 - 1/24n A. -6 / 2N-1 B. -6 / 2N+1 C. 6 / 2N+1

Oksi-84 [34.3K]

Answer:

Option B is the correct answer

Step-by-step explanation:

The exact expression is:

$\frac{\frac{1}{4n}-\frac{1}{2}}{\frac{n}{6}-\frac{1}{24n} }$

Taking LCM in numerator and denominator can simplify the expression. Further simplifying the expression can give us the final result, as shown below:

$\frac{\frac{1-2n}{4n} }{\frac{4n^{2}-1 }{24n}} \\\\=\frac{1-2n}{4n}\times\frac{24n}{4n^{2}-1 }\\\\=\frac{1-2n}{4n}\times\frac{24n}{(2n+1)(2n-1)}\\\\ =-\frac{2n-1}{4n}\times\frac{24n}{(2n+1)(2n-1)}\\\\ =-\frac{6}{2n+1}$
