3x = 2x + 20
3x - 2x = 20
x = 20
Answer:
a=10
b=37
Step-by-step explanation:
a+5 is equal to the opposite line, 15. 10+5=15 therefore, a must equate to 10
3b is the same angle as 111 therefore 3*b has to equate to 111. 111 divided by 3 equals 37. B has to then equate to 37 to make the proper angle.
Hope my explanation wasn't too confusing, and hope this helps! Good luck!!!
The distance from his home to the store is represented by
41x² + 357x - 15.
We know the distance from the store to the library, and the distance from his home to the library. We also know the store is between the two. To find the missing distance, we subtract the two polynomials we have:
(54x² + 310x + 8) - (13x² - 47x + 23)
Combining like terms:
54x² - 13x² = 41x²;
310x -- 47x = 310x + 47x = 357x;
8-23 = -15
This gives us
41x²+357x-15
