X = 4 y = 3 4x-3y=7 x=13-3y
4(13-3y) -3y =7
52 -12y -3y =7
-15y=-45
-y=-3 y = 3
x=13-(3*3)
x=13-9
x =4
Answer:
you didn't upload a picture for us to see
Area of Rectangle = Width × Length
Area = 600 Sq ft
Width = 20
Length = L
20L = 600
L = 600/20 = 30
Floor is 30' long
3 hundreds equal to 300
17 tens equal to 170
13 ones equal to 13
1 tenths equal to 0.1
2 hundreths equal to .02 when added all together you'll get
483.12 <---- The answer
Yo sup??
This question can be solved by applying the properties of similar triangles
the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 35
The similarity property used here is called AAA ie angle angle angle property as all the three angles of the 2 triangles are equal.
therefore we can say
5x/45=20/36
x=5 units
Hope this helps
