Answer:
The lake frontage of lot A is 50.9yd
The lake frontage of lot B is 58.4yd
The lake frontage of lot C is 64.7yd
d) The prices of the other lots, from least to greatest, are 286,836.94 and 317,779.96
Step-by-step explanation:
This means 21g is 100-16%=84%.
21x0.16=3.36
21+3.36=24.36
2x + 3y = 1
y = 3x + 15
Get the same variables on each side
3y = 1 - 2x
y = 15 + 3x
Multiply both sides of that second equation by 3 so we can subtract.
3y = 1 - 2x
3y = 45 + 9x
Subtract the equations from each other.
0 = -44 - 11x
Solve.
44 = -11x
-4 = x
Use x in an earlier equation to find y.
y = 3x + 15
y = 3 * -4 +15
y = -12 + 15
y = 3
x = -4, y = 3
Solve for X in the 2nd equation:
x+2z = 0
Subtract 2z from both sides:
x = -2z
Replace x in the first equation with -2z
-2z +y -z = 1
Combine like terms:
-3z +y = 1
Add 3z to both sides:
y = 3z +1
Replace x and y in the 3rd equation:
2(-2z) + 2(3z+1) = 4
-4z + 6z + 2 = 4
2z +2 = 4
2z = 2
z = 1
Now replace z with 1 in the other equations for x and y:
x = -2z = -2(1) = -2
y = 3z +1 = 3(1) +1 = 3+1 = 4
So you have x = -2, y = 4 ans z = 1
The answer would be written as (-2,4,1)
Answer:
536.6
Step-by-step explanation:
First I found the area for the rectangles which is (15x10) multiplied by 3.
Then I found the area for the triangles which is A=(1/2)(8.66)(10). Which equals 43.3, then multiplied that by 2.
Add all the areas together (150)(3)+(43.3)(2)=536.6
