Answer:
y = (2/5) OR y = (6/5)
Step-by-step explanation:
The first step is isolating the expression within the absolute value bars. The first thing we can do is subtract both sides by 8. If we do that, we get -2|4-5y| = -4. Now, to completely isolate the absolute value, we would have to divide by -2. This yields |4 - 5y| = 2. Finally, we can remove the absolute value bars. However, to do this, we need to first understand what an absolute value bar does to an equation. Lets say that |x| = 2. Absolute value describes the DISTANCE of some quantity from 0 (on the number line). Therefore, x (which is inside the absolute value bars) can be either positive or negative 2 (they are BOTH two units away from 0). Similarly, in this case, (4 - 5y) can either be 2 or -2 (because the absolute value of both is 2). Now we have two possible solutions to solve for:
4 - 5y = 2 OR 4 - 5y = -2
5y = 2 OR 5y = 6
y = (2/5) OR y = (6/5)
If we plug both of these answers back into the equation we can see that they both check out.
Answer:
The Growth of sunflower duing 3 weeks is 8.5 inches or 8 (1/2).
Step-by-step explanation:
Given:
Growth of sunflower each week .
To find :
Total growth during 3 weeks?
Solution:
According to given data:
Growth is
- 1st week=2 and 1/2 inches=5/2=2.5 inches .
- 2nd week =2 and 3/4 inches=11/4 inches.
- 3rd week=3 and 1/4 inches=13/4 inches.
Total growth is given by,
=growth of (1st week +2 week+ 3 week)
=5/2+11/4+13/4
=34/4
=17/2
=8 and 1/2 inches.
Hence the overall growth is about 17/2 or 8.5 inches in 3 weeks .
