Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo

Keith_Richards [23]

Hi i'd be glad to help you with this equation.

basically all we have to do is find (65%) of 455*.

65% of 455* = 295.75

Next.

455 + 295.75 = 750.75

So, to check my work I have 750.75 miles in total.

I have already driven 455 miles of 750.75 miles.

Using subtraction we subtract our distance from our total.

750.75 - 455 = 295.75

So, in total your answer to this problem is (295.75)

Hope this helps.
Have a great day!

A $104.000 selling price with $24000 down at 8 1/2% for 25 years results in a monthly payment of

romanna [79]

*******************************************************
(See attached formula)
Loan Principal = 104,000 - 24,000 = 80,000
rate = 8.5 / 1,200 = 0.0070833333 
time = 25 years = 300 months

Monthly Payment = 0.0070833333 + [ 0.0070833333 / ((1.0070833333)^300 -1)) ] *principal

Monthly Payment = 0.0070833333 + [ 0.0070833333 / ( 8.3104129461 -1)] * 80,000
Monthly Payment = 0.0070833333 + [ 0.0070833333 / ( 7.3104129461)] * 80,000
Monthly Payment = (0.0070833333 + 0.00096893750767) * 80,000
Monthly Payment = 0.00805227080767 * 80,000
Monthly Payment = 644.18

What is an equation of the line that passes through the point (-3,-1) and is

Yuri [45]

Answer:

y = -2x - 7

Step-by-step explanation:

x - 2y = 6

-2y = -x + 6

Divide the whole equation by (-2)

$\frac{-2y}{-2}=\frac{-x}{-2}+\frac{6}{-2}\\\\y = \frac{1}{2}x - 3$

slope = 1/2

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

$=(-1)*\frac{2}{1}\\\\= -2$

(-3, - 1)

y -y1 = m(x -x1)

y - [-1] = -2(x - [-3])

y + 1 = -2(x + 3)

y + 1= x* (-2) + 3*(-2)

y + 1 = -2x - 6

y = -2x - 6 - 1

y = -2x - 7
