Mary: x yrs old
Mike: 3x yrs old
In four yrs:
Mary: x+4 yrs old
Mike: 3x+4 yrs old
As the text of task:
3x+4=2(x+4)
3x+4=2x+8
3x-2x=8-4
x=4
Mary is 4 yrs old
Answer:
B
Step-by-step explanation:
60+15w≥115
-60 -60
15w≥55
w≥4
60+15(4)≥115
60+60≥115
six less than x is
x-6
because you are taking 6 away from x or finding a value of 6 less than x.
There it is, I don't know what you mean by "describe the solution"

Answer: C) a 180 degree rotation about its center</h3>
Explanation:
Draw out a rectangle and make sure it's not a square. So you could have it be longer than it is tall. Imagine rotating that rectangle 180 degrees. The before and after (preimage and image) will be identical. The same applies if we slanted the sides of this rectangle. This shows that any parallelogram has rotational symmetry.
Side note: any rectangle is a parallelogram, but not the other way around.
