Natasha_Volkova [10]

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Step-by-step explanation:

Let slice of pizza cost x and a 12-ounce cola cost y.

Then Sara's order cost: 2x+y=3

and Sydney's order cost: 3x+2y=4.75

From the first equation we have: y=3-2x and put this to the second equation:

3x+2(3-2x)=4.75

3x+6-4x=4.75

x=1.25

y=3-1.25*2=0.50

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

In a zoo there are zebras and peacocks sharing the same area. There is a total of 14 zebras and peacocks. If you count, there is
Arturiano [62]
If we take the number of Zebras to be x and that of peacocks to be y
Then x + y = 14
A zebra has 4 legs while a peacock has 2 legs, 
Therefore the total number of legs will be 4x + 2y  which is equal to 36 .
Therefore, we have two equations 
    x + y = 14
   4x + 2y = 36    solving them simultaneously using elimination
   
4x +2y = 36
2x + 2y = 28 ( multiplying the first equation by 2 to eliminate y)
     2x = 8 ( subtracting the equations)
        x = 4  
       y = 14 -(4) 
          = 10
Therefore, there are 4 zebras and 10 peacocks in the zoo

MAXImum [283]

Answer:

$113.90

Step-by-step explanation:

Find the cost of the meal with sales tax:

90 x 0.075 = 6.525

Add that to the original cost of the meal:

90 +  6.525 = 96.525

Find the cost of the tip:

96.525 x 0.18 = 17.3745

Add the tip to the meal price:

96.525 + 17.3745 = 113.8995
