Answer:

x = -1 and x = 11

Step-by-step explanation:

|4x + 10|  =  |5x - 1|

Out of that equation above we can rewrite these in different versions of signs separately:

- (4x + 10) = 5x - 1

4x + 10 = 5x - 1

We can finally solve for x in those equations:

- (4x + 10) = 5x - 1 \\  - 4x  -  10 = 5x - 1 \\  - 9x  = 9 \\ x =  - 1

4x + 10 =  5x - 1 \\ 4x + 10 =   5x  - 1 \\  - x =  - 11 \\ x = 11

After 10 months the simple interest earned annually on an investment of $6000 was $769. Find the interest rate to the nearest te
Lady bird [3.3K]
Simple interest = $769
Principal = $6000
Rate = ?
Time = 10 months (must convert to years if in months) = 10/12 = 0.833
Formula
I = prt
Substitute
769 = 6000 × r × 0.833
769 = 4998r
Divide both sides by 4998
769/4998 = 4998r/4998
0.15386 = r
(to the nearest tenth of a percent) = 0.15
Therefore, your rate is 0.15%.
