<span>Sales went from 48 pairs to 60 pairs:
total change = 60 - 48 = 12
percentage change = 12 / 48 = 0.25 = 0.25*100% = 25%
Answer: 25%</span>
Since david ate a quarter of the pizza he ate 3 slices. John ate 4 slices. 4+3=7 , 12-7=5 pieces of pizza are left
The answer is [-1,26]. The range between 4 and 9 is 5, and the range between 8 and -10 is 18, so you'd apply this to [4, 8] in order to find the other endpoint.
Answer:
value of x = -2
value of y = 1
Step-by-step explanation:
here's the solution :-
the given equations are :
=》-4x - 4y = 4
=》6x + 4y = -8
adding both equations, we get ;-
=》-4x - 4y + 6x + 4y = 4 - 8
=》2x = -4
( positive and negative 4y get eliminated )
=》x = -4 / 2
=》x = -2
plugging the value of x in equation 2 we get ,
=》6x + 4y = -8
=》(6 × -2) + 4y = -8
=》-12 + 4y = -8
=》4y = -8 + 12
=》y = 4 / 4
=》y = 1
