3[-x+(2x+1)]=x-1 whay is x?

Mathematics
1 answer:
stiks02 [169]3 years ago
4 0

Answer:

well tbh, x will always just equal 1 unless it's next to another number.

Step-by-step explanation:

so the answer is x= 2 btw idk just in case ig

3 ( - x + 2x + 1) = x -1 ( add 1 and 2x together)

3 ( x + 1 ) = x- 1. ( -x and + 2x are like terms)

get rid of parentheses. 3x + 3 = x - 1

moved variable (x) to the left hand side and change its sign. 3x - x + 3 = -1 / 3x - x = 1 - 3

2x - 1 - 3

2x = - 4

x= -2

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. After c years, Calvin has $658. 80. Makay
Drupady [299]

The approximate difference between Calvin and Makayla's number of years of money invested is 2 years.

<h3>What is compound interest?</h3>

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

A=P\left(1+\dfrac{r}{t}\right)^{t}

Here, A is the final amount (principal plus interest amount) on the principal amount of P with the rate of r in the time period of t.

Calvin deposits $400 in a savings account and Interest rate is 5 present compounded monthly.

As the final amount Calvin has $658.80 in c years. Thus the monthly compound interest can be given as,

658.8=400\left(1+\dfrac{5}{12\times100}\right)^{12c}\\\dfrac{658.8}{400}=\left(\dfrac{1205}{1200}\right)^{12c}\\c\cong10\rm years

Now Makayla deposits $300 in a different savings account that accrues 6% interest compounded quarterly. The final amount she gets is $613.4 in m years. Thus,

613.4=300\left(1+\dfrac{6}{12\times100}\right)^{12m}\\\dfrac{613.4}{300}=\left(\dfrac{1206}{1200}\right)^{12m}\\c\cong12\rm years

Thus, the approximate difference in the number of years that Calvin and Makayla have their money invested is 2 years.
