The GCF is the Greatest Common Factor, which means that it is the highest number that divides exactly into two (or more) numbers, in this case 55 and 100.  You start off by listing all of the factors of both numbers.  When you have finished, you find the highest factor that goes into them both, and that is the answer. 

1, 5, 11, 55. 
1, 2, 4, 5, 10, 20, 25, 50, 100. 

As you can see, the highest number that goes into them both is 5.  Therefore, the GCF of 55 and 100 is 5.

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is
Salsk061 [2.6K]

Answer:

Step-by-step explanation:

Let the cost of one soft taco = s

Let the cost of one burrito  = b

 

So  we have this system

 

3s  + 3b  = 11.25  

4s +  2b   = 10.00   (1)

 

Divide  the first equation through by 3   and we have that

 

s +  b  =  3.75         subtract  b from both sides

s   =  3.75 - b   (2)

 

Sub  (2) into (1)  and we have

 

4 (3.75 - b)  +  2b  =  10.00      simplify

15 - 4b  + 2b   = 10.00

-2b + 15  =10.00      subtract 15 from both sides

-2b  =  - 5.00         divide both sides by -2

b  = 2.50

 

And using (2)

s  =  3.75 - 2.50   =   1.50

 

 

So...  a soft taco  1.50 and a burrito is  2.50
