Answer:
x = 43
Step-by-step explanation:
3x - 31 = 2(x+6)
3x - 31 = 2x+ 12
x =43
Answer:
f(- 2) = 23
Step-by-step explanation:
substitute x = - 2 into f(x) and evaluate
f(- 2) = 3(- 2)² - (- 2) + 7 = 12 + 4 + 7 = 23
Make the solutions equal to each other and then solve for x. Once you find x. Plug it back in to either side of the newly formed equation
Your answer is 178.75
97.5-(-81.25)
you want to apply the keep change change rule
97.5+81.25 = 178.75
