Answer:

\frac{3}{4} x +  \frac{4}{7} y =  \frac{5}{4} x - 1 \\  \frac{4}{7} y =  \frac{5}{4} x - 1 - \frac{3}{4} x \\  \\  \frac{4}{7} y =  \frac{5x - 4 - 3x}{4}  \\  \frac{4}{7} y =  \frac{2x - 4}{4}  \\  \\ y = \frac{2x - 4}{4} \div   \frac{4}{7} \\ y =  \frac{2x - 4}{4} \times  \frac{7}{4}  \\  \\ y =  \frac{14x - 28}{16}  \\  \\ y =  \frac{14x}{16}  -  \frac{28}{16}

How many hours a week do you have to work to make $5000 a month?
nasty-shy [4]
It depends on how much you earn in an hour .. so for example if your earn 100$ in 1 hour so you need to work for 50 hours in total because 5000 divided the amount of money you make in a single hour which is 100 in this example will be 50 hours in total .. to get the amount of hours you need to work a week you should know that the month has 4 weeks .. so 50 divided 4 equals 12.5 hours

Help with my algebra homework
Maru [420]

Let's solve your equation step-by-step.

2x /5 + 3 = x/10 - 1

Step 1: Simplify both sides of the equation.

2x /5 + 3 =  x/10 - 1

2/5x + 3 = 1/10x - 1

Step 2: Subtract 1/10x from both sides.

2/5x + 3 - 1/10x = 1/10x - 1 - 1/10x

3/10x + 3 = -1

Step 3: Subtract 3 from both sides.

3 /10x + 3 - 3 = -1 - 3

3/10x = -4

Step 4: Multiply both sides by 10/3.

(10/3) * (3/10x) = (10/3) * (-4)

x = -40/3

The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreci
irina1246 [14]
Analyzing the given values and the given equation, we have the following:
A = $25,000
r = 0.11
t = 6

The equation has the form:
y = A (1-r)^t
Plugging in the given values into the equation,
y = $25,000 (1 - 0.11)^6
y = $25,000 (0.89)^6

Therefore, the answer is
A. y=25,000(.89)^6
