1 answer:

Answer:

13. 1/2, 5/8, 3/4

16. 7/12, 3/5, 2/3

Step-by-step explanation:

make them have the same denominator.

13) 1/2 x 4 = <u>4/8</u>, <u>5/8</u>, 3/4 x 2= <u>6/8</u>

16) Grab two fractions let's say 3/5 and 2/3

Multiply 3/5 denominator (5) with 2/3 numerator (2)

It's 10 and place it above the number you multiplied the numerator from so it's above 2/3.  Do it again but with 2/3 denominator (3) and 3/5 numerator (3). Multiply 3 and 3 you get 9. Place the 9 above 3/5. We know that 9 is less than 10 so 3/5 is less than 2/3. You can do this with any two fractions.

PLEASE HELP
valina [46]

Answer:

Step-by-step explanation:

You have 3 unknowns: a, b, and c.  It's our job to find them algebraically.  I'm going to start with the point where x = 0 and y = 7.  You'll see why in a minute.  Filling in the standard form of a quadratic

y=ax^2+bx+c  using (0, 7):

7=a(0)^2+b(0)+c  gives you that c = 7.  We will use that value now when we write the next 2 equations.  Now the point (-2, 19):

19=a(-2)^2+b(-2)+7  and

19=4a-2b+7 so

12 = 4a - 2b

Now for the next point (-1, 12):

12=a(-1)^2+b(-1)+7  and

12=a-b+7  so

5 = a - b

Now we have a system of equations (the 2 bold font equations) that we will solve by elimination:

 12  =  4a  -  2b

  5  =   a   -    b

Multiply the bottom equation by -4 to get a new system:

 12  =  4a  -  2b

-20  = -4a  +  4b

Add those together to get rid of the a terms and end up with

-8 = 2b so

b = -4

Now we can sub in -4 for b to solve for a.  I'm using the second bold type equation to do this:

5 = a - (-4) and

5 = a + 4 so

a = 1 and the equation for the quadratic function is

y=x^2-4x+7

Currently 1 United States dollar equals 19.25 Mexican pesos. If you exchanged 725 Mexican pesos for US dollars, what amount woul
Irina18 [472]

Answer:

The value of 725 Mexican pesos is equals to 37.66 US dollars

Step-by-step explanation:

Given as :

The value of 1 US dollar equals to 19.25   Mexican pesos

The total amount of Mexican pesos = 725

Now,

∵  19.25  Mexican pesos equals to 1 US dollars

∴    725  Mexican pesos equals to  \frac{725}{19.25} = 37.66 US dollars

Hence The value of 725 Mexican pesos is equals to 37.66 US dollars Answer
