Answer:
n = -1
Step-by-step explanation:
First distribute the -4
15-4n+8=27
Combine 8 & 15
-4n+23=27
Subtract 23 from each side
-4n=4
Divide each side by -4
n=-1
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
Answer:
n= -1
Step-by-step explanation:
15-4(n-2)=27 do the () first
15-4n+8=27 subtract 15 and 8 from both sides to get the -4n alone
-4n= 4 divide by -4
n= -1

A recipe requires 8 cups of baking powder. You can only use 2/3 cups. How many 2/3 cups do you need for the recipe?
Answers
Answer:
Step-by-step explanation:
6/3 is 2 cups.
2/3 times 3 is 2.
12 of the 2/3 cups is your answer
That is my way of thinking. If you want the answer basically you divide 8 by 2/3. When you divide a fraction you multiply by its reciprocal.
8 3 =24 = 12
1 2 2 1
8 times 3/2 is equal to 24/2 or 12

The sum of the digits in a two digit number is 14. If you reverse and double the original number, and then add the result to the original number, the sum is 222. Find the original number
Answers
Answer:
Step-by-step explanation:
Let the two digits be x and y, where x is the tens digit and y is the units (ones) digit.
Then the number is 10x + y.
From the question,
The sum of the digits in a two digit number is 14,
That is, x + y = 14 ....... (1)
Also, from the question,
If you reverse and double the original number, and then add the result to the original number, the sum is 222
If the number is reversed, the new number will be 10y + x; and if this is doubled, we will get 2(10y + x).
Now, if this is added to the original number (10x + y), the sum is 222.
That is,
2(10y + x) + (10x + y) = 222
Then,
20y + 2x + 10x + y = 222
12x + 21y = 222 ........ (2)
Now, we will bring the two equations together and solve simultaneously.
x + y = 14 ....... (1)
12x + 21y = 222 ........ (2)
From equation (1)
x + y = 14
Then, x = 14 - y ...... (3)
Substitute the value of x in equation (3) into equation (2)
12x + 21y = 222
12(14 - y) + 21y = 222
168 - 12y + 21y = 222
168 + 9y = 222
9y = 222 - 168
9y = 54
∴ y = 54/9
y = 6
To determine x, substitute the value of y into equation (3)
x = 14 - y
∴ x = 14 - 6
x = 8
∴ x = 8 and y = 6
Recall that, the two digits are x and y, where x is the tens digit and y is the units (ones) digit.
Hence, the original number is 86.

Ray Flagg took out a 60-month fixed installment loan of $12,000 to open a new pet store. He paid no money down and began making monthly payments of
$221.
Ray's business does better than expected and instead of making his
30th
payment, Ray wishes to repay his loan in full. Complete parts a) through
c).
Answers
Answer:
Since the question is incomplete, I looked for similar questions:
a) determine apr of installment loan
b) how much interest will Ray save by paying off the loan early
c) what is the total amt due to pay off the loan?
a) first we will determine the effective rate:
PV annuity factor = loan / monthly payment
PV annuity factor = $12,000 / $221 = 54.2986
Using an annuity table, knowing that the number of periods is 60, we can see that the interest rate is 0.333%.
APR = 0.333% x 12 = 4%
b) I prepared an amortization schedule to determine Ray's balance after the 29th payment.
After the 29th payment, Ray's balance will be $6,498.54
in order to pay off the debt completely, he needs to pay $6,498.54 + $22.32 in interests = $6,520.86.
He will be able to save $331 in interests
c) $6,520.86
