Answer:
pounds.
Step-by-step explanation:
To find how much butter Robin had after baking, we first need to find how much she initially had.
According to the problem Robin had 7/8 of a pound of butter.
She used 1/4 of a pound of butter to make a cake.
This gives us:
Since we have different denominators, we need to first find the LCD of the fractions.
Now that they have the same denominators, we can then subtract them directly.
pounds.
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Divide the first equation by 2 and add the result to the second equation. This will eliminate x.
... (-4x -2y)/2 + (2x +4y) = (-12)/2 +(-12)
... 3y = -18 . . . . . collect terms
... y = -6 . . . . . . . divide by 3
Substitute this into either equation to find x. Let's use the second equation, where the coefficient of x is positive.
... 2x +4(-6) = -12
... 2x = 12 . . . . . . . . add 24
... x = 6 . . . . . . . . . . divide by 2
The solution is (x, y) = (6, -6).
