Add/subtract the like terms:

(11x - 3) + (4x - 1)  =  11x - 3 + 4x - 1  =  11x + 4x - 3 - 1  =  15x - 4

To find the mass of each one, divide the total mass by the number of hamburgers.

--->   3.25 kg / 25  =  0.13 kg per hamburger.

Try these one at a time:

The first formula:  m = h/55.

Replace h with 1, m = 1/55  --- this doesn't work.

The second formula:  m = 55/h

Replace h with 1, m = 55/1 = 55; replace h with 2, m = 55/2 =27.5 --- this doesn't work.

The third formula:  m = 55h

Replace h with 1:  m = 55(1) = 55. Replace h with 2:  m = 55(2) = 110. Replace h with 3:  m = 55(3) = 165. Replace h with 4:  m = 55(4) = 220. Replace h with 5:  m = 55(5) = 275. Replace h with 6:  m = 55(6) = 330.    --- these all work!

Let's try these, one at a time:

The first formula:  s = 22w  

Using this equation, replace w with 1, and s = 22. Replace w with 2, and s = 44. Replace w with 3, and s = 66. Replace w with 4, and x = 88. Replace w with 5, and s = 110.

This works! This must be the correct formula.

If it didn't work, then try the second formula, etc.

As a common fraction, 3 1/3  =  (3 x 3 + 1)/3  =  10/3

And, 1 5/12  =  (1 x 12 + 5)/12  =  17/12

To divide common fractions, multiply by the reciprocal:

(10/3) ÷ (17/12)  =  (10/3 x (12/17)  =  (10 x 12) / (3 x 17)  =  120/51  =  40/17

If she wants 25% Fruit Loops, she needs to find 25% of 6 cups.

--->   25% of 6 cups   --->  0.25 x 6 cups  =  1.5 cups.

This formula describes a parabola. The highest point will be at its vertex.

The x-value of the vertex of the parabola  y  =  ax² + bx + c   is:  x  = -b/(2a)

For the equation:  h  =  -16t² + 96 t + 4, the values of a, b, and c, are:  a = -16, b = 96, and c = 4.

t  =  -b/(2a)  =  -96/(2·-16)  =  -96/-32  =  3

--->  So, it takes 3 seconds to get to its highest point.

To find how high it goes, substitute 3 back into the original equation:  h  =  -16(3)² + 96 (3) + 4  =  148 feet.

It is the first one.  The mL is half of the persons weight so dividing it by 20 is the most logical way.

can you please explain how you got that answer?

190 or 19                                                                                           

8*3-5*25+8

24-125+8

-93

If linear functions are not parallel, they cross over because if graphed, they will intersect at one area.

it's the last one, because the equation is b=w+6, right? so if the number of weeks is one, the number of books is 7. If the number of weeks is two, the number of books is 8. 8 is not double 7 and therefore the answer is the last option.

approx. 16373 days and around 15 hours

well, if y=18x-7, we can substitute that value into the first equation to get 3x-90x+35=15. Therefore, -87x=-20 and x=$$20/87$$. Therefore, y=18(20/87)-7. y=1586/87-7 and then y=959/87.

.175 as a percent is 17.5% b/c if it is a decimal move the decimal 2 places left for percent and if it is a percent u move it 2 places to the right to turn it into a decimal

thanks CPhill :))

That vine is old and the one true answer is 19

 If you've got questions, we've got answers! So post your questions here---one question per posting. 

I thought it would be 10,000cm? Oh okay thanks

1000m / 1 km * 100cm / 1 m  = 100,000 cm / 1 km
