C = 3b+2d is the same as 3b+2d = C
Let's isolate d. To do this, we first need to subtract 3b from both sides
3b+2d = C
3b+2d-3b = C-3b
2d = C-3b
Then divide both sides by 2
2d = C-3b
2d/2 = (C-3b)/2
d = (C-3b)/2
Take note of the parenthesis as they are very important. We want to divide ALL of C-3b over 2. We don't want to just divide -3b over 2.
The answer choices you have aren't 100% clear but I have a feeling your teacher meant to say d = (C-3b)/2 instead of d = C-3b/2 for choice A
If that assumption is correct, then the answer is choice A.
Answer:
-10x
Step-by-step explanation:
-2x-4=-6x
-4-6x = -10x
2 and 1/2 because 2 shots would be 50% and 3 would be 75% so it would have to be 2 and 1/2 shots.
X = 2/3 + 5/6 + 4/6 + 5/6 = 9/6 = 3/2
Answer:
<h2>A. -3x + 17</h2>
Step-by-step explanation:
5 - 3(x - 4) <em>use the distributive property: </em><em>a(b + c) = ab + ac</em>
= 5 + (-3)(x) + (-3)(-4)
= 5 - 3x + 12 <em>combine like terms</em>
= -3x + (5 + 12)
= -3x + 17
