The answer is 11.1
Because -(-7.2)+3.9= 11.1
Answer:
(-1, -1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -11+9)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(0+-1)/2 = -1/2
(-1, -1/2)
243 medium cups - 79 = large cups (164)
164 large cups + 56 = small cups (220)
she used 220 small cups.
First let establish the eqautionlet y be the total costx is the number of orders
y = 3x + 115
since the minimum order is 25x >= 25
then The school can spend a maximum of $800
800 <= 3x + 115
800 - 115 <= 3x685 <= 3x685/3 <= x228.33 <= x
