Answer:
x=-2
Step-by-step explanation:
25+6x=21+4x
Step 1: Simplify both sides of the equation.
6x+25=4x+21
Step 2: Subtract 4x from both sides.
6x+25−4x=4x+21−4x
2x+25=21
Step 3: Subtract 25 from both sides.
2x+25−25=21−25
2x=−4
Step 4: Divide both sides by 2.
x=−2
Answer:

Answer:
The answer is .9.
Step-by-step explanation:
Steps Ex. 1 Ex. 2
Round a number to the nearest tenth 3.14 .883
Find the hundredths' place. 3.14 .883
Less than 5, round the tenth down. 3.1
If it is 5 or more, round the tenth up. .9
That is your explanation. The answer is .9
The answer is about 20.15 years ie 20 years 1 month and 24 days.
to solve it first you would have to pick just about any arbitrary salary value eg:lets say $3000.so now you plug the value in this formula:
where p is the principle value or rather the initial value and x is the time during which the money changes.now we have to find x since we the 3000 and 6000 (the double of 3000) and the percentage per year which is 3.5.plugging in the values into the formula we get:
now we solve for x using a scientific calculator and we get 20.14879168
we convert to 2 decimal place and get 20.15 year.
btw once you got the years now u can insert any value of your salary and assuming that the 3.5% remain constant you should be able to obtain just about the double of your salary.
hope that helped :)
