Answer:
The Width of each side of the bookmark in centimeters = 5cm
Step-by-step explanation:
A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters
The formula for perimeter fo a rectangle =
P = 2L + 2W
Where L = Length
W = Width
Hence: From the above question:
38cm = 2 × 14 cm + 2 W
38cm = 28cm + 2W
2W = 38cm - 28cm
2W = 10cm
W = 10cm/2
W = 5cm
Hence, the Width of the rectangle(each side of the bookmark in centimeters) = 5cm
X+1=y and 3y-7=2x are your two equations.
Substitute x+1 in for y
3(x+1)-7=2x
3x+3-7=2x
x-4=0
x=4
Plug in 4 for x in either equation to solve for y
x+1=y
4+1=y
5=y
x=4 and y=5
Hope I could help!
Answer:
y = -x + 3
Step-by-step explanation:
The equation of a line with slope equal to -1 and y-intercept equal to 3 has the form
y = mx + b. With m = -1 and b = 3, we get: y = -x + 3
Think about this problem, please. Is there any way in which you could be clearer about what you wanted to learn?
So basically it makes a cone
one way to solve is
Vcone=(1/3)hpir^2
r=3
h=2
V=(1/3)(2)pi3^2
V=2pi3
V=6pi
aprox pi=3.141592
V=18.849
round
V=18.8 in^3
Add both of the volume of dirt,
50+25
75 cubic feet of dirt
Hope this helps.
