Answer:

but I guess it can be all real numbers and shi te

Step-by-step explanation:

-3x-3 = -3(x+1)

-3x-3 = -3x-3 (which means -3(x+1) is basically putting x in evidence)

That way we have either:

-3x-3 = 0

-3x = 3

x = 3/-3

x = -1

-3(x+1) = 0

-3 cannot be 0 so:

x+1 = 0

x = -1

I bought a car of 650,000 and sold it for 520,000. Find the lost Percent ?

Tom [10]

Answer:

20% decrease in value.

Step-by-step explanation:

Do 650,000 divided by 100 to find what 1% of the original price is:

650,000 divided by 100 = 6,500

To find what percentage of the original price 520,000 is, we divide it by 1% of the original cost (6,500):

520,000 divided by 6,500 = 80 (percent)

So if 520,000 is 80% of 650,000 the car has decreased in value by 20%.

Solve. 5 3 + 8 4 -2 5 3 6 11 -216 12

Archy [21]

Answer:

$-\frac{11}{12}$

Step-by-step explanation:

$\frac{\frac{5}{8}+\frac{3}{4}}{-\frac{2}{3}-\frac{5}{6}}$

Working on the denominator,

$-\frac{4}{6}-\frac{5}{6}=\frac{-9}{6}=-\frac{3}{2}$

$\frac{\frac{5}{8}+\frac{3}{4}}{-\frac{3}{2}}$

Working on the numerator,

$\frac{5}{8}+\frac{3}{4}=\quad \frac{11}{8}$

$\frac{\frac{11}{8}}{-\frac{3}{2}}$

$-\frac{11\cdot \:2}{8\cdot \:3}=-\frac{22}{24}=-\frac{11}{12}$
