Answer:

y=x+4

Step-by-step explanation:

So, let's start with the fact that we have two numbers. Let's call one of them "x" and the other one "y." Let's also assume that "y" is the larger number and "x" is the smaller number.

 

We know that both of them added together (the sum) gives us 74. Mathematically, that means:

 

x+y=74.

 

We also know that the larger number ("y") is 4 more than the smaller number ("x"). Another way to say this is, if you have the smaller number and add 4 more to it, you'll end up with the larger number. Mathematically, this means:

 

y=x+4

 

Since we know that y=x+4, we can put "x+4" into the first equation for "y", giving us:

 

x+(x+4)=74

 

Simplifying gives us:

 

2x+4=74

   -4   -4

  ---------

2x=70

---  ---

2    2

 

 

x=35

 

Since we now know that x=35, and we know that y=x+4, we now know that:

 

y=(35)+4

y=39

 

Now that we have both of the numbers, we should check our work to ensure it's correct:

 

Does 39+35=74?      Yes it does.

 

Is 39 (the larger of the two numbers) four more than the smallest number (35)?    Yes it is.

A group of friends go out for lunch. If they order 2 hot dogs and 4 cheeseburgers, the bill will
Trava [24]

Answer:

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

Step-by-step explanation:

Let x = cost of a hot dog

     y = cost of a cheeseburger

(1)      2x + 4y = 23.5           (2)    5x + y = 18.25    

                                                           y =  18.25 - 5x

        2x +4(18.25 - 5x) = 23.5

         2x + 73 - 20x = 23.5

         -18x + 73 = 23.5

                  -18x = -49.5

                       x = 2.75                       y = 18.25 - 5(2.75)

                                                           y = 18.25 - 13.75

                                                           y = 4.50

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

The odds in favor of a horse winning a race are 9:5. find the probability that the horse will win the race.
Alexeev081 [22]

Answer:

9/14.

Step-by-step explanation:

The probability is given as a fraction or percentage.

9:5 odds in favour of a horse winning  means the horse will win 9 races for every 5 it does not win.

So the probability that this horse will win is 9/(9+5)

= 9/14.
