Answer:
the 8 ounce has a better unit rate
Step-by-step explanation:
You divide 8 by 2.79 and get 2.87. Then you take 15 and divide it by 5.54 and get 2.7. Since 2.87 is the bigger number that's the correct answer
Slope is 5
Y intercept is 5
Solve:
5x-y=-5
(Isolate Y by adding y to both sides to get it alone and adding 5 to both sides)
Y=5x+5
We know that slope (m) is w the X so in this case it is 5
And then to find the y intercept we substitute O for X.
Y=5(0)+5
Y=5
Y has a bigger area, 660.185 while x is, 254.34
The difference is 405.845
Given information:
Total animals = 13
Total legs = 40
Assumed all animals have their legs intact ...
Pig = 4 legs
Chicken = 2legs
Assumed all chickens:
Total legs = 2 x 13 = 26
Extra legs = 40 - 26 = 14
Extra legs belongs to the pig (each pig has extra 2 legs)
14 ÷ 2 = 7
There are 7 pigs
13 - 7 = 6
There are 6 chickens
---------- OR ALGEBRAICALLY --------
Let the number of pigs be x and number of chickens be y
pigs = x
chickens = y
x + y = 13 -------------- (1)
4x + 2y = 40 ---------- (2)
From (1):
x + y = 13
x = 13 - y -------------- sub into (2)
4(13 - y) + 2y = 40
52 - 4y + 2y = 40
52 - 2y = 40
2y = 52 - 40
2y = 12
y = 6 ----------- sub into (1)
x + 6 = 13
x = 13 - 6
x = 7
x = 7, y = 6
pigs = 7, chickens = 6
