Answer:
3w+7=25
Step-by-step explanation:
3×w+7=25
3×w=25 - 7
w=18÷3
w=6
When they say to solve for c, they just want you to isolate it. We can start by subtracting b from both sides to give us:
x - b = cd
After this, we can divide both sides by -d to finish isolating the variable c; remember that -cd is -1(c)(d):
= c
Therefore, c =
The nominal value - without discounting the inflation rate - of income was $ 3000.
If the interest rate was 6%, a rule of three is enough to find the value of the original investment.
3000 - 6%
x - 100%
x = 50,000
The value of the investment was $ 50,000
In this case, the inflation rate also requires a simple calculation.
Inflation corroded $ 1000 dollars of income of $ 3000
Therefore the inflation rate will be 1000/3000 = 33.3%
Answer:
4.77*10^5<7.47*10^5
Step-by-step explanation:
4.77*10^5=477000
7.47*10^5=747000
East common multiple is the smallest multiple both numbers can go into. (Example: the LCM of 10 and 4 is 20, because both 10 and 4 go into 20 and 20 is the smallest number both 10 and 4 can go into. You could just multiply them both, but you'd get 40 and since its a bigger number it would be harder to work with.)
<span>Least common denominator is just the least common multiple as a denominator. (Example: if you wanted to find the LCD of 5/7 and 1/10, you'd have to find the LCM of the demoniators (7 and 10) and then just use that as the denominator when adding fractions with unlikely denominators.) Sorry for such a long answer :P</span>
