Answer:
x=10
y=25
Step-by-step explanation:
3x-10+5x+30+6x+20=180
14x+40=180
14x=180-40
14x=140
x=10
9x-10=4y-20
9(10)-10=4y-20
90-10=4y-20
80=4y-20
80+20=4y
100=4y
25=y
Answer: it's -1
Step-by-step explanation: Hope this helps

Step-by-step explanation:
The answer is the square root of 101.75
Assuming that the sandwich Is a square, after cutting it diagonally, it turns into 2 triangles. To look for a missing length of a triangle, you use Pythagorean’s theorem a^2+b^2=c^2
Since c is 12 and a is 6.5 you just square 12 and square 6.5
144 42.25
Subtract it
101.75
You then have to find the square root of it. You can leave it as it is as √101.75 or just solve for it and round it to 10.09
