Rewrite the equation as;
-0.3(7n - 31.2) = 0.456
Divide each term by 0.3 and simplify;
-7n + 31.2 = 1.52
Move all terms not containing n to the right side of the equation;
-7n = -29.68
Divide each term by -7 and simplify;
<u>n = 4.24 </u>
Answer:
5%
Step-by-step explanation:
First, find the amount of tax:
5250 - 5000
= 250
Divide this by the original price of $5000 to find the percent of import tax:
250/5000
= 0.05
So, the percent of import tax is 5%
Answer:
A. 21
Step-by-step explanation:
So theres 4 months and each month it costs $50

The we do the total cost minus $200 and we get $21
Hope this helped and if it did can i get brainliest
Answer:
It will take them 42 hours
Step-by-step explanation:
Brianna rate = one bed for 2 hours
But for one hour = 0.5 bed per hour
Wesley rate = two bed for 3 hours
For one hour= 2/3 bed per hour
So their total rate for one hour
= 1/2 +2/3
= 7/6 bed per hour
If they received an order of 49 beds
It will take them x hours
Rate= bed/hour
7/6= 49/x
X= 49/(7/6)
X= 49 * 6/7
X= 7*6
X= 42 hours
Part A
A geometric sequence is where the terms increase by the same ratio.
Example:
7, 14, 28, 56, ...
We start at 7 and double each term to get the next term. The common ratio is 2.
============================================================
Part B
The next step is to subtract the two equations straight down. This will cancel the vast majority of the terms, and allow to solve for to get a fairly tidy formula. Refer to part C for more info.
