3x/4 +2/3=x/3 find the exact answer to the simplest form

1 answer:

5 0

First, we need to get rid of the denominator. to do so, we will simply multiply all terms by 12 (which is the result of 3*4).
(3x/4)(12)+(2/3)(12)=(x/3)(12)
9x + 8 = 4x
then we will separate the variable in one side and solve to get its value
9x-4x = -8
5x = -8
x = -8/5

An investor bought some shares at a price of £14.88 each. The price of the shares drops to £11.45. Find the percentage loss.

frozen [14]

Answer:

23%

Step-by-step explanation:

Calculate the percentage loss as shown

percent loss = $\frac{loss}{originalprice}$ × 100%

loss = 14.88 - 11.45 = 3.43, hence

percent loss = $\frac{3.43}{14.88}$ × 100% = 23%

The perimeter P of a square (measured in inches) is expanding in size at a constant rate of change of 4 inches per inch with res

vivado [14]

Answer:

a. 10 inches

b. 8 inches

c. $\frac{dP}{ds} = 4$

Step-by-step explanation:

a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches

b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.

c. We can express the change in the square's perimeter P in terms of the change in the square's side length s as

$\frac{dP}{ds} = 4$
