Answer:
Step-by-step explanation:
3x + 20
You will need to find out what x represents by doing that you add 80+60 which equals 140 now you know what your missing
3 times what + 20 equals 140
40×3=120+20=140
Your answer would be 3•40+20=140
<span>5/ 8 x 4/ 5
=20/40
=1/2
answer is </span>A. 1/2
I think inside the triangle......
B < 11 = the board is shorter than 11 cm.
B > 11 = the box contains more then 11 books.
B < 12 = there are fewer than 12 beetles in a jar
B > 12 = the building is taller than 12 ft.
I hope this helped :)

Answer:
20 miles
Step-by-step explanation:
The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).
d² = 12² +16²
d² = 144 +256 = 400
d = √400 = 20
The two trains are 20 miles apart.

<em>Additional comment</em>
You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)
