(-3x+3y=-9)-(-3x+y=7)
-3x+3x+3y-y=-9-7
2y=-16
y=-8, making -3x+3y=-9 become:
-3x+3(-8)=-9
-3x-24=-9
-3x=15
x=-5
So the solution to this system of equations is the point (-5, -8)
Well look I really don’t know have a good day hope you do good on remember god loves you and have ahold day
Answer:
Step-by-step explanation:
Triangles
Area of a triangle = 1/2 b * slanted height
b = 6 m
h = 9 m
Area of 1 triangle = 1/2 * 6 * 9
Area of 1 triangle = 27
Area of all 4 triangles = 4*27 = 108 m^2
==================
Base area
The base is a square. All 4 sides are equal.
The formula for a square is s^2
Area = (6 m)^2
Area = 36 m^2
Total area
Total Area = 108 m^2 + 36 m ^2
Total Area = 144 m^2
Answer:
24
Step-by-step explanation:
6 ÷ 15 = 0.4
X to Y = 20 × 0.4 = 8
Y to Z = 25 × 0.4 = 10
Perimeter: a + b + c
6 + 8 + 10 = 24
Even I am surprised by what I wrote. Hopefully, it is right and helps you ^-^ Please comment if you have any questions.
