Answer:
r = 47
Step-by-step explanation:
r - 38 = 9
r- 38 + 38 = 9 + 38
simplify
r = 47
Answer:
The width of the equation is 3 and the length is 9
Step-by-step explanation:
This problem was kind of simple for me to answer. The first thing I did was divide the 4 sides of the perimeter into sections which would bring me to find that it was 6 inches on each side then I divided that by 2 bringing me to the answer of 3. Then I decided to multiply 3 by 3 which brought me to the answer 9. I decided to try it around the perimeter which would be....
9+9+3+3=?
I added the 9's first which gave me 18 .Then added the 3's together which gave me 6. The final step I added 6 and 18 together and got 24.
Giving the fact that the length is 3 times greater than the width I came to the conclusion that....
3 is the width and 9 is the length.
Answer:
(i) 4000
(ii) $5.00
Step-by-step explanation:
Let no. of shares of Company A be X
Let share price of Company B on Day 7 be $y
Share price of Company B on Day 12 = $(y-0.50)
(i)
Consider Day 7:
4.60x - 2000y = 7400................ (1)
Consider Day 12:
4.80x - 5000(y-0.50) = -5800
4.80x - 5000y + 2500 = -5800
4.80x - 5000y = -8300............... (2)
(1)*2.5:
11.5x - 5000y = 18500................. (3)
(3)-(2):
11.5x - 4.80x - 5000y + 5000y = 18500 + 8300
6.70x = 26800
x = 4000
(ii)
Sub. x = 4000 into (1):
4.60(4000) - 2000y = 7400
-2000y = 7400 - 18400
-2000y = -11000
y = 5.5
Share price of Company B on Day 12
= 5.50 - 0.50
= $5.00
