3x+2x-13=47
5x-13=47
5x=60
x=12
15 + .65x = 80
15 + .65x = 80
15 - 15 + .65x = 80 - 15
.65/.65x = 65/.65
x = 100

For this case, the first thing we are going to do is model the desk as a rectangle.
The area of the rectangle is given by:
A = w * l
Where,
w: width
l: length
Clearing we have:
l = A / w
Substituting values:
l = (15/16) / (5/4)
Rewriting we have:
l = (15/16) * (4/5)
Simplifying we have:
l = (3/4) m
Answer:
The length of the desk in meters is:
l = (3/4) m
Answer:
Step-by-step explanation:
tax = 7% of $45.09 = 0.07×$45.09 ≅ $3.16
Total cost = $45.09 + $3.16 = $48.25
Area of a circle A=r*r*3.14
we have a diameter but we need radius for the formula so what's the radius
r=d/2 so r=17/2=8.5yd
the area=8.5*8.5*3.14
area=226.86yd sq
