20 earth pounds on the moon would equate to 3.31 pounds.
Answer:
11.2 square feet
Step-by-step explanation:
3.2 + 4 =7.2 2 +2 = 4
7.2 + 4 = 11.2
Answer:
64,26
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
The box means its is a 90 degree angle
90 + 2x+ x-6 = 180
Combine like terms
84+3x = 180
Subtract 84 from each side
84+3x-84 = 180-84
3x=96
Divide by 3
3x/3 = 96/3
x = 32
The top angle is
2x = 2*32 = 64
The bottom right angle is x-6
32-6 = 26
Answer:
We can write:
x + y = -2
xy = -80
We can rewrite the first equation as x = -y - 2 and then plug that into the second equation to get (-y-2) * y = -80 → -y² - 2y = -80 → y² + 2y - 80 = 0 → (y - 8)(y + 10) = 0 → y = 8, -10. Substituting these values into the first equation we get x = -10, 8 so the answer is (x₁, y₁) = (-10, 8) or (x₂, y₂) = (8, -10).
