Answer:
Both Lindsay and Sharon are wrong.
Step-by-step explanation:
When Lindsay was doing her problem, she put 100 on the bottom and 45 on the top, when it should have been the other way around.
Sharon would have been correct if she had used the right measuring unit. 2/5 of a milliliter should have been 2/5 of a liter.

Answer:
P(x) = -1.1x +49
Step-by-step explanation:
You are given the percentage in 2000 (for x=0) as 49, and told that its rate of change is -1.1 percent per year. So, with a slope of -1.1 and an intercept of 49, the slope-intercept form of the linear equation becomes ...
P(x) = -1.1x +49
_____
The slope-intercept form for slope m and y-intercept b is ...
y = mx + b
Answer:
k=−5
Step-by-step explanation:
−3(k+7)−5k+4=23
(−3)(k)+(−3)(7)+−5k+4=23(Distribute)
−3k+−21+−5k+4=23
(−3k+−5k)+(−21+4)=23(Combine Like Terms)
−8k+−17=23
−8k−17=23
Step 2: Add 17 to both sides.
−8k−17+17=23+17
−8k=40
Step 3: Divide both sides by -8.
−8k
−8
=
40
−8
k=−5
Answer:
k=−5
