Answer: x = 4

Step-by-step explanation:

$\dfrac{3}{5}(10 + 5x) - \dfrac{1}{3}(6x + 3)=9$

$\dfrac{3}{5}(10 + 5x)(15) - \dfrac{1}{3}(6x + 3)(15)=9(15)$ multiplied by common denominator

3(10 + 5x)(3) - 1(6x + 3)(5) = 9(15) reduced all fractions

90 + 45x - 30x - 15 = 135 distributed

15x + 75 = 135 simplified (added like terms)

15x = 60 subtracted 75 from both sides

x = 4 divided 15 from both sides

–2.1x + 3.7 -5 + 4.9x

becomes

–2.1x + 3.7

The price of Stock A at 9 A.M. was $14.83. Since then, the price has been increasing at the rate of $0.12 each hour. At noon

BARSIC [14]

Answer:

0.5 hours

Step-by-step explanation:

Let the x be the number of hours after noon.

We have the following equation:

14.83 + 0.12(x + 3) = 15.33 - 0.15x
14.83 + 0.12x + 0.36 = 15.33 - 0.15x
0.12x + 0.15x = 15.33 - 15.19
0.27x = 0.14
x = 0.14/0.27
x ≈ 0.5
