Answer:
Step-by-step explanation:
3x-20=x+40
2x=60
x=30, then
y+x+40=180, knowing x=30
y+30+40=180
y+70=180
y=110
Answer:
2 feet
Step-by-step explanation:
Since each piece of wood is 2/3 of a foot tall, and there are two pieces of wood stacked on top of each other, you need to add 2/3 twice to get the total height of the pile.
2/3 + 2/3 = 6/3
6/3 = 2
Therefore, the pile is 2 feet tall.

Answer:
Answer:The answer is C
Step-by-step explanation:
Because what we have in x^2, the y value can never be negative, no matter what the x value is. When it is squared, it will always remain positive. Because there is a y intercept of 1, and x cannot be negative, you can only go up form one. So therefore, all of the y values have to be greater than or equal to one.
