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
Answer:
check your math
Step-by-step explanation:
The first subtraction was correct:
36 -7 3/4 = 28 1/4
The second subtraction needs to be revisited.
28 1/4 -6 2/4 = 27 5/4 -6 2/4 = 21 3/4
__
You can do what you did, but you need to pay attention to the signs.
28 1/4 -6 2/4 = (28 -6) +(1/4 -2/4) = 22 - 1/4 = 21 3/4
The result of subtracting 2/4 from 1/4 is -1/4, not +1/4.
_____
The length of the first cut piece was 21 3/4 inches.
You divide to get the answer
Answer:
x=1.818minutes
Step-by-step explanation:
3/60 miles per minute for walk
8/60 miles per minute for run
0.05x + 0.1333y=1
x+y=10
x=y-10
0.05(y-10) + 0.133333y = 1
0.05y-0.5+0.133333y=1
0.18333y=1.5
y=8.18minutes
x=10-8.18
x=1.818minutes
Hello There!
To find the quotient of
÷
,
we need to multiply by the reciprocal meaning that the fraction
stays the same but we flip the numerator and
denominator for our second fraction so it will end up being
which is the same thing as 8 so the second choice
is your answer.
