Answer:
y=10 ( number of acrobat)
Step-by-step explanation:
let x be the elephant and y the acrobat
elephant has 4 legs and acrobat 2
4x+2y=40
x+y=15 ⇒x=15-y
substitute for x in the equation:
4(15-y)+2y=40
60-4y+2y=40
-2y=40-60
y=-20/-2
y=10 ( number of acrobat)
number of elephant=15-10=5 elephants
Answer:
6 2 points, 2 3 points
Step-by-step explanation:
x = 2point shots, y=3 point shots
total points: 2x +3y=18
total made: x+y=8
x= 8-y, derived from isolating x in total made equation
plug into equation 1
2(8-y) + 3y =18
-2y+16+3y= 18
y +16 = 18
y = 2
x = 8-2 = 6
6 2 points, 2 3 points

Answer:
The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.
Step-by-step explanation:
Let the price of a taco be x and the price for a small glass of milk be y.


Multiply the first equation by 2:

Subtract the new third equation from the second equation:


Hence, the price for a small glass of milk is $0.95.
Substitute y into the first equation.


Therefore, the price for a breakfast taco is $1.15.
Hope this helped!
