The sandwich is .20 because the milk will be .10 and the sandwiches are for 20 so 20+20=40, 40+10=50 I hope this helps you
Try finding the area or perimeter of the triangle then
Answer:
x=-7
Step-by-step explanation:
Regroup terms.
8x-2=7x-98x−2=7x−9
2 Subtract 7x7x from both sides.
8x-2-7x=-98x−2−7x=−9
3 Simplify 8x-2-7x8x−2−7x to x-2x−2.
x-2=-9x−2=−9
4 Add 22 to both sides.
x=-9+2x=−9+2
5 Simplify -9+2−9+2 to -7−7.
x=-7x=−7
