Answer:
4 2/3
Step-by-step explanation:
4(2x -3) + 8(x - 4) = 2(2x + 6)
Distribute
8x -12 + 8x -32 = 4x +12
Combine like terms
16x - 44 = 4x+12
Subtract 4x from each side
16x-4x-44 =4x-4x+12
12x-44 = 12
Add 44 to each side
12x-44+44 = 12+44
12x = 56
Divide each side by 12
12x/12 = 56/12
x = 14 / 3
Changing to a mixed number
x = 4 2/3
Answer:
The volume is ten(10)and the surface is also ten(10)
so what i did was a long process but it worked i started by taking $5550 and multiplying it by .12 which gave me $666 then i did 9500-5550=3950 then i took 3950 and multiplied it by .09 and it gave me 355.5 then i added those together and got 1021.5 so i needed to increase the amount i invested at 12% to get a higher yield. i did this process a few more times and each time i increase the amount of money i invested at 12% by 25 dollars and i finally arrived at:
5900 x .12 = $708
9500-5900=3600
3600 x .09 =$324
708+324= $1032
so your answer is that you invested $5900 at 12% and $3600 at 9%.
add me as a friend if you like because i am generally good at math. hope this helped.
