PIT_PIT [208]

Answer:

Monthly Living Expense = 2375

Monthly Fixed Expense = 1975

Step-by-step explanation:

Let monthly living expense be "x"

and monthly fixed expense be "y"

<u>"monthly living expenses were 400 more than his monthly fixed expenses":</u>

x = 400 + y

<u>"Richard total monthly expenses were 4350":</u>

x + y = 4350

Putting Equation 1 in Equation 2:

(400 + y) + y = 4350

400 + 2y = 4350

2y = 3950

y = 1975

Now, x = 400 + y = 400 + 1975 = 2375

A car requires 45 liters of petrol to travel a distance of 330 km.

Genrish500 [490]

Answer:

1) The car can travel 623.3 km with 85 liters of petrol.

2) The car owner has to pay $303.8.

Step-by-step explanation:

1) The distance traveled with 85 L of petrol can be found as follows:

$d = \frac{330 km}{45 L}*85 L = 623.3 km$

Hence, the car can travel around 623 km with 85 liters of petrol.

2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:

$x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8$

Therefore, the car owner has to pay $303.8.

I hope it helps you!

The interest on the loan is
.. I = P*r*t = 3000*.09*180/365 = 133.15

Your effective rate is
.. r = I/(Pt) = (100 +133.15)/(3000*180/365) = 15.8%

Use the substitution method to solve the system of equations. y=-8x and 4x-y=3

Artyom0805 [142]

Answer:

<h2>x = 1/4 and y = -2</h2>

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=-8x&(1)\\4x-y=3&(2)\end{array}\right\qquad\text{put (1) to (2):}\\\\4x-(-8x)=3\\4x+8x=3\\12x=3\qquad\text{divide both sides by 12}\\x=\dfrac{3}{12}\to x=\dfrac{1}{4}\\\\\text{put the value of x to (1):}\\\\y=-8\left(\dfrac{1}{4}\right)=-2$
