Answer:
Width = 9
Step-by-step explanation:
(P=2L+2W) = 72
L = 3W<- length is triple the width
(P = 2(3W) + 2W) = 72
P = 8W =72
W = 9
X² - 1 = 0
x² = 1
x = +/-√1
x = +/- 1
Answer:
The answer is "(0,0)"
Step-by-step explanation:
In the given some information is missing that is point so, the correct answer to this question can be described as follows:
book Number = x
overall Book weight = y
Neither x nor y can be negative. We have to be positive values, then.
Since x indicates the number of books, that must be a positive integer. It can not be a decimal number or fractional number.
So the only viable solution from the given options is (0, 0).
To find Emma's profit, you will calculate her cost for all the items and the amount of money she collected when she resold the items.
Subtract the two amounts to find her profit or how much money she made when she sold them.
Amount Emma paid: (2 x 35) + (3 x 75) + (5 x 4) = $315
Amount the items sold for: (2 x 65) + (3 x 136) + (5 x 15) = $613
$613 - $315 = $298
Emma made $298 in profit on her items.
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600
