Answer:
Step-by-step explanation:
I think you mean solve for x
Set up a proportion.
The proportion should be set up as
Large Parts of ADE = Similar Parts of ABC
DE/BC = AD/AB
DE = x
BC = 6
AD = 20
AB = 10
x/6 = 20/10 Multiply by 6
x = 20*6 / 10
x = 120 / 10
x = 12
Hey buddy
3 rd part is correct
Hope it helps :)
Answer:
Width of the rectangle = 10 feet
Length of the rectangle = 25 feet
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = x feet
Length of the rectangle = 3x - 5 feet
Perimeter of the rectangle = 70 feet
Perimeter of a rectangle = 2(length + width)
70 = 2{x + (3x - 5)}
70 = 2{x + 3x - 5}
70 = 2(4x - 5)
70 = 8x - 10
70 + 10 = 8x
80 = 8x
Divide both sides by 8
x = 80 / 8
= 10
Width of the rectangle = 10 feet
Length of the rectangle = 3(10) - 5
= 30 - 5
= 25 feet
0.000576 is the right awnser
849-1.5=847.5
6.8-4.8=2
847.5 divided by 2 =423.75
