2x+3y=6 (for x) 

Subtract 3 from both sides

2x  = 6 -  3y      divide both sides by 2

x  =  [ 6 -  3y ]  / 2

Fm-3=Q (for F)   →      F  =   [Q + 3] / m

Where did you get these "multiple choice" answers from? Are they from your textbook, or from an assignment?.

,l v

in order to solve for x just pretend 3y doesn't exist. block it out. then you just have 2x=6. from there it's a simple one-step equation. x=3

for F you would first add three making the equation Fm=Q+3 then divide by M making the equation F=Q+3 over M

T=4.6sin(pi/182(d-6))+5

T = 4.6 sin(π/182 (26 - 6)) + 5

T = 4.6 sin(0.34523 radians) + 5

T = 4.6 x 0.3384131 + 5

T = 1.556700 + 5

T = 6.5567 hours AM.

I don't get the answers for these two...

1 - Murphy obtains a 15/5 mortgage to finance $133,500 at 4.95%. How much principal and interest will he have already paid when his balloon payment is due?

Multiply the monthly payment calculated above X 60 months =Principal + interest.

2 - Julie and Brian are financing $245,000 to purchase a house. They obtained a 30/5 balloon mortgage at 5.25%. What will their balloon payment be?

You should write the number of stars in "scientific notation", thus: 6 x 10^22 stars.

[6 x 10^22] / 3,000 =2 x 10^19 stars - more than a human eye can see.

using 4,6,7,8 to equal 15 using order of operations

[8 / 4]  + [6 + 7] =

   2      +   13     = 15

Since 30318 isn't a multiple of 17198 by a whole number it is a decimal

Density =Mass / Volume

D =0.29956 kg / 117.52 cm^3,     1 cm^3 = 1 mL

D =0.002549..... kg/mL. P.S. Your units should be consistent. That is, Kg should go with m^3, and g(grams) should go with cm^3. So that: 0.002549 x 1,000 =2.549 g/cm^3.

A mL is generally used for "liquid measure" and cm^3 for "dry measure".

This is called a "Perpetual Annuity".

$5,000 / 5% =$100,000. This is the value of this Perpetuity at the start of year 5.

PV =$100,000 / 1.05^4

PV =$82,270.25 - Its present value as of today. I have assumed that the $5,000 payment will start at the beginning of year 5, so that it would 4 years from now. If it starts at the end of year 5, then you will divide $100,000 / 1.05^5.
