Hey there!

3/4k + 3/8k = 1/2

COMBINE the LIKE TERMS

(3/4K + 3/8k) = 9/8k

NEW EQUATION: 9/8k = 1/2

MULTIPLY 8/9 to BOTH SIDES

8/9 * 9/8k = 8/9 * 1/2

CANCEL out: 8/9 * 9/8 because it gives you 1

KEEP: 8/9 * 1/2 because it helps solve for your result (also known as giving you the result of the k-value)

NEW EQUATION: k = 8/9 * 1/2

SIMPLIFY IT AND YOU WILL HAVE YOUR RESULT

k = 4/9

Therefore, your answer is: k = 4/9

Good luck on your assignment and enjoy your day!

A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $100 each day to operate the bank an
horrorfan [7]

Answer:

The restaurant Manager can afford 6 employees for the day.

Step-by-step explanation:

Manager can spend at most of $400.

Total Money ≤ $400

Cost to operate bank = $100

Cost for each employee = $50

Let number of employees for the day bex

Hence the equation will become;

50x + 100 \leq 400

Solving this equation we get;

50x + 100 \leq 400\\50x \leq 400-100\\50x \leq 300\\x\leq \frac{300}{50}\\\\x\leq 6

Hence, The restaurant Manager can afford 6 employees for the day.

Find all equations that would graph the same line as 5x-3y=8. what else?
ioda
I agree with all your choices. First, you would convert all the equations to slope-intercept form.
Convert the initial equation 5x - 3y = 8 to get y = 5/3x + (-8/3)

We can't do anything with -5 = 3y = -8 because of the equal signs, therefore, option A is eliminated.

Option B in slope-intercept is y = 5x + -8, that is no where close to <span>y = 5/3x + (-8/3), so B is eliminated.
</span>
Option C in slope-intercept form is <span>y = 5/3x + (-8/3), the same as the initial equation, so choice C is correct.
</span>
Option D in slope-intercept form is y = 2.5/-1.5x + 4/-1.5, dividing the fraction results in y = -1.667x + -2.667, -1.667x is the equivalent of -5/3 and -2.667 is the equivalent of (-8/3). It does not matter if the slope is positive or negative, as long as they're the same. Choice D is correct.

Option E in slope-intercept form is y = -25/-15x + 8/-15, dividing -25/15x results in 1.667x, but 8/-15 is -0.534, -0.534 is not equal to -2.667. Choice E is eliminated.

Option F in slope-intercept form is y = -15/-9x + 24/-9, -15/-9 is 1.667 and 24/-9 is -2.667, this is equivalent to  y = 5/3x + (-8/3). <span>Choice F is </span>correct<span>.

I agree with all your answers! :) </span>
