Step-by-step explanation:
- 5x+12=6x+7 (opposite sides of a parallelogram are equal)
- 12=x+7 (subtract 5x from both sides)
- x=5 (subtract 7 from both sides)
- Now put x in any of the equations-- 5(5)+12=37 or 6(5) +7=37
Answer:
47 degrees
Step-by-step explanation:
The sum of angles in a triangle must be 180
32+101+x=180
133+x=180
x=47.
Answer:
85 miles.
Step-by-step explanation:
Lets begin by figuring out the number of miles in 4 inches. Since every 2 inches make 40 miles, we can figure out that there are 80 miles in 4 inches. To figure out that .125 part, we multiply 40 by .125, to get 5. We can add 80 plus 5 to get our grand total of 85 miles.
Add 65+57 and subtract it from 180 then you get the third angle
Answer:
x = 45/4
Step-by-step explanation:
2x - 3/4 + x = 2x + 3/2 + 9
- 3/4 + x = 3/2 + 9
- 3/4 + x = 21/2
x = 21/2 + 3/4
x = 45/4
