Answer:
4
x - ----- = 3
y
Step-by-step explanation:
I'm assuming that you mean:
4
x - ----- + 2 = 5
y
Subtracting 2 from both sides, we get
4
x - ----- = 3
y
adding 4/y to both sides yields:
4
x = 3 + -----
y
Answer:
80°
Step-by-step explanation:
Arc CB has the same measure as the central angle intercepting it. Angle COB measures 80°, so arc CB measures 80°.
The shop had $2,000 in sales on Monday.
If it fell by 10% on Tuesday, then 2000 * 0.10 equals the percentage it dropped, so it dropped by $200. So they only had $1,800 in sales on Tues.
If they fell by another 20% on Wednesday, 1,800 * 0.20 equals a $360 drop. Now we're at $1,440.
The sales then increased by 25% of Monday's total # of sales. 25% of Monday's sales is 2,000 * 0.25 which equals a $500 increase. Now we're at $1,940.
Now that we're done with everything, how far are we from the beginning? That's the net change. :) We began at $2,000 on Monday, and ended with $1,940 on Thursday. 2000 - 1940 is 60, so 60 = your net change.
TLDR: Sold $2,000 on Mon, sold $1,800 on Tues, sold $1,440 on Wed, and then sold $1,940 on Thurs. The net change is $60.
