Answer:
- Heather's model represents the greater area.
greater.
Step-by-step explanation:
The formula for calculate the area of a rectangle is:

Where "l" is the lenght of the rectangle and "w" is the width.
The formula for calculate the area of a square is:

Where "s" is the side lenght.
In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:

Therefore, substituting these values into the formula
, we get that the area is:

Since Heather's model represented 18 ft by 18 feet, we can identify that:

Substituting this value into
, we get this area:

Notice that Heather's model represents the greater area.
To calculate how much greater it is, subtract the areas. Then:

Answer:
3/2
Step-by-step explanation:
2y+3x=3
This represents a linear equation and the format for a linear equation is
y = mx+b
m = slope
b= y-intercept
we have to subtract 3x from both sides to make this the y=mx+b form
2y=-3x+3
and divide both sides by 2
y = (-3x+3)/2
3/2 or 1.5 is the y-intercept
the constant of a linear equation (or 3) is the y-intercept, if there is no constant then the y-intercept is 0
Answer:
1. a = 2
2. x = 12
3. w = 2
Step-by-step explanation:
1. ok so 2a/5 we would want to separate it to 2/5 and a/5
2/5 x a/5 = 2a/5
next we want to subtract 2/5 from 8/10
8/10 - 2/5 or 8/10 - 4/10 = 4/10
now you have a/5 and 4/10
a/5 = 4/10
now you multiply each side by 5
a/5 x 5 = a
4/10 x 5 = 20/10 or 2
a = 2
2. ok so the x is kinda on it's own for this one but we still wan to get the x and the other numbers on opposite sides
1/16x + 1/4 - 1/4 = 1/16x
1/2 + 1/4 = 3/4
now we do that same last step
1/16x / 1/16 = x
3/4 / 1/16 = 12
x = 12
3. ill do one more and if you need more help just tell me
for this on we have the w on both sides so we have to get the variable(w) and the numbers on opposite sides
2w - 2 + 2 = 2w
1/2w + 7 - 1/2w = 7
2w + 1/2w = 5/2w or 2 1/2w
7 - 2 = 5
now we have to divide each side by 5/12 or 2 1/2
5/2w / 5/2 = w
5 / 5/2 = 2
w = 2
Answer:
33.5
Step-by-step explanation:
just separate this shape into triangles and rectangles and find the area of those shapes separately then add them altogether.
hope this helped (:
