Answer:
$221
Step-by-step explanation:
Hello!
The total cost s $627.83, for one desk that costs $185.83, and two identical chairs (c).
The equation: $185.83 + 2c = $627.83
This equation represents the cost of the desk plus two chairs of the same price, which adds up to the total price.
Solve for c:
- $185.83 + 2c = $627.83
- 2c = $442
- c = $221
Each chair, c, costs $221.
7x + 10 = 13(12x - 3) + 14x
7x + 10 = 156x - 39 + 14x
10 + 39 = 156x - 7x + 14x
49 = 163x
x = 49/163
Okay. When it comes to multiplying decimals, you multiply them just like you would do whole numbers. However, solving them by paper, you would add a decimal point into the answer, depending on how many numbers are behind the decimal point in the numbers being multiplied. In this case, the decimal point will go in front of two numbers, because there are two numbers behind the decimal point in -1.2 and 0.4. Know that the answer will be negative, because there is one negative and one positive number.
Multiply both numbers. -1.2 * 0.4 is -0.48. There. The product is -0.48.
Answer:
Their savings will be same after 25 weeks.
Step-by-step explanation:
The difference in both person's saving is $ 2/week
$5-$3=$2
The total difference in the starting point is $50 if we divide $50 by $2 we will get a number of 25 which is the number of weeks it will take both savings to reach at a same level
Calculation:
Starting point $150
Savings $5/week
5*25+150= $275
Starting point: $200
Savings 3$/week
3*25+200= $275
Our decimal system is base 10 and has digits from 0 to 9
For a 12 base system you have to add two digits. They will be A and B.
So the numbers of three digits that start with B are B01, B02, B03, B04, B05, B06, B07, B08, B09, B0A, B0B, B10, B11, ...
I made a long sequence to help you see more clearly how it works, but you only need to see that the number before and after B0B are B0A and B10.
That is the answer: B0A and B10.
