Ineeed this ∠1 and ∠2 are supplementary angles. m∠1=4x+3 m∠2=3x−5 what is the value of x? a. x = 26 b. x = 178 c. x=1787 d. x=927

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

Prove that 16^4-2^13-4^5 is divisible by 11.
