So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Tripling the recipe would require 3 times 1 1/3 cups of sugar, or 4 cups:
3(4/3) = 4
So if Karen already has 1/2 cup of sugar on hand, she needs (4 - 1/2), or 3 1/2, more cups of sugar to triple the recipe. (answer)
8/6 or 1 2/6 or 1 1/4
Explanation:
1/4 + 1/4 = 2/4
2/4 = 3/6
5/6 + 3/6 = 8/6
8/6 simplified is 1 2/6 or 1 1/4
Answer:
4 bottles
Step-by-step explanation:
Let o represent the number orange juice bottles Megan bought. Then the total number of juice bottles is ...
o + 12 = 4o
12 = 3o . . . . . . . subtract o
12/3 = o = 4 . . . . divide by the coefficient of o
Megan bought 4 bottles of orange juice.
