Answer: She has to score a minimum of 92 marks to take her average to 80
Step-by-step explanation:
Let the equation be
Three months total = 76 x 3 = 228
(x + 228) / 4 = 80
x + 228 = 80 x 4
x = 320 - 228
x = 92
It’s the same so 36.6 because if they are vertical angles both sides are congruent
Answer: 11
you want to add 17 to -6 and then x will = 11
