25,000(4+3x) =125,000
Amanda [17]
To solve this equation, first we have to use the distributive property to eliminate the parentheses on the left side of the equation.

If done correctly, your simplified equation should be 

100,000 + 75,000x = 125,000

Next, we would subtract 100,000 from both sides, resulting in the equation

75,000x = 25,000

Finally, we would divide both sides of the equation by 75,000, resulting in your final answer of 

x= 25,000/75,000

However, many mathematics teachers ask for fractional answers to be simplified.  To simplify fractions, we first find the GCF of both numbers, and then divide both the numerator and the denominator by the GCF.

The GCF of 25,000 and 75,000 is 25,000.

So, in simplest form, your final answer is 

x=1/3

Write 0.614¯¯¯ as a fraction in simplest form.
Verizon [17]

Answer:

307/500

Step-by-step explanation:

307 is a prime number.

The way to find this out is to take 0.614 and multiply it by 1,000 because then it will be a natural number. 0.614*1,000=614.

now you take 614/1,000 because that's what you multiplied it by and simplify it.

614/2 and 1,000/2=307/500 and this cannot be simplified any more than this because 307 is a prime number.

the ball is 150g heavy and it is dropped from 300m, what is the velocity of the ball just before it touches the ground
boyakko [2]

Answer:

77.5 m/s

Step-by-step explanation:

Once the ball is dropped from the height, it converts all its potential energy into kinetic energy:

P. E = K.E\\mgh = \frac{1}{2}mv^2

Using this equation, and the data we have to find the velocity of the ball:

mass = 150 \ g \\gravity = 10 \ m/s^2\\height = 300 m

P.E = mgh\\150 \times 10 \times 300 = \frac{1}{2} \times 150 \times v^2\\\\150 \times 10 \times 300 = 75 \times v^2\\\\v^ 2 = \frac{150 \times 10 \times 300 }{75}\\\\v^2 = 6000\\\\v = \sqrt {6000}\\\\v = 77. 5 \ ms^{-1}
