You have to subtract by \frac{1}{3}a on EACH of  the sides you're working with!

\frac{4}{5}a + 3 - \frac{1}{3}a - 8 - \frac{1}{3}a

Which gives us: \frac{7}{15}a + 3 = -8

Now, that we got these steps out of the way, let's subtract 3 from the sides you're working with! 

\frac{7}{15}a  + 3 - 3 \\ = -8 -3

 \frac{7}{15}(a) = -11

We have gotten these  steps out of the way now lets multiply by \frac{15}{7} on your sides because, it is the reciprocal of \frac{7}{15}

So,  \frac{15}{7}( \frac{7}{15}a ) =  \frac{15}{7}  (-11)

Cancel out: \frac{15}{7}( \frac{7}{15} ) because, it equals to:1

\frac{15}{7}(-11) =   \frac{-165}{7}

Therefore, your answer is:  \frac{-165}{7} aka 23\frac{4}{7} 

Good luck on your assignment and enjoy your day

The height of players on a football team is normally distributed with a mean of 74 inches, and a standard deviation of 1 inch. I
Andreas93 [3]

Answer:

Step-by-step explanation:

Let x be the random variable representing the height of players on the football team. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = standard deviation

n = number of samples

From the information given,

µ = 74 inches

σ = 1 inch

n = 50

x = 74 inches

the probability that a player is less than 74 inches tall is expressed as

P(x < 74)

For x = 74,

z = (74 - 74)/(1/√50) = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

Therefore,

P(x < 74)

The players less than 74 inches is

0.5 × 50 = 25 players

Which statement best describes the conditions for f ( x ) = a ( b ) x to be a model for exponential growth?
irina1246 [14]

Exponential functions grow is the base is greater than 1, while you have an exponential decay if the base is between 0 and 1. Finally, exponentials are not defined, as real functions, if the base is negative.

So, the answer is D, b > 1

My parents recently moved to the Poconos, they got 30 or more inches of snow from this last snow storm. It took my Dad 2 hours t
never [62]

To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:

10ft______2hs

120ft_____xhs

If the cleaning rate is the same, then the ratios between both are the same:

\frac{2}{10}=\frac{x}{120}

From this expression, you can determine the time by multiplying both sides of the equal sign by 120

\begin{gathered} 120(\frac{2}{10})=\frac{120x}{120} \\ 24=x \end{gathered}

It will take him 24 hours to clear the 120ft driveway.

-2/3 x -9/8 x -4/5 x -1
Lerok [7]

Answer: 0.6

Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.

(-2/3x-9/8x )-(4/5x)-(1)

So (-2/3x-9/8x) equals -11/24x

And  -11/24x-4/5x equals -151/120x

So -151/120x-1 ends up being 0.6.
