Answer:

66.75m

Step-by-step explanation:

Area of Triangle: 4.5m

\frac{bh}{2}

height is 4.5m

base is 2m

overall height is 10m so 10-3.5-5= height of triangle

overall base is 10.75m so 10.75-3.25-2.5-3= base of triangle

Area of the smallest rectangle: 13.5m

base is 3m (provided)

height is 4.5m (same as triangle)

Area of the medium sized rectangle: 16.25m

base is 2.5m (provided)

height is 6.5

overall height is 10m so 10-3.5= the height of this rectangle

Area of largest rectangle: 32.5

base is 3.25m (provided)

heigh is 10m (provided)

A dormitory manager buys 38 bed sheets and 61 towels for $791.50. The manager get another 54 bed sheets and 50 towels for $923 f
-Dominant- [34]
38b + 61t = 791.50....multiply by 27
54b + 50t = 923.....multiply by -19
-------------------
1026b + 1647t = 21370.5 (result of multiplying by 27)
-1026b - 950t = - 17537 (result of multiplying by -19)
------------------add
697t = 3833.50
t = 3833.50 / 697
t = 5.50 <=== cost of each towel

38b + 61t = 791.50
38b + 61(5.50) = 791.50
38b + 335.50 = 791.50
38b = 791.50 - 335.50
38b = 456
b = 456/38
b = 12 <== cost of each bed sheet

so the cost of 1 towel and 1 bed sheet is : 12 + 5.50 = 17.50

Last one, what is the algebraic way to solve 1/5(t+2) = 5/8 ? Please provide the correct explanation :)
madam [21]

1/5(t+2)=5/8
First you do 1/5 times t+2
1/5t+2/5=5/8
Then you subtract 2/5 from both sides
1/5t+2/5 - 2/5 = 5/8 -2/5
Simplify that and you get
1/5t = 9/40
Divide both sides by 1/5 (multiply by the reciprocal)
And you get 9/8 or 1 1/8
I hope this helped!
