Answer: 138
Step-by-step explanation:
Answer:
y = 50x - 1100
Step-by-step explanation:
83 x 6 = 498
all six of her scores need to equal at least 498 for an 83 average
83 + 84 + 93 + 77 + 85 = 422
498-422 = 76
she needs a 76
5/6*x + 2= 4/5*x -3
5/6*x - 4/5*x = -3 -2
x*(5/6-4/5)= -5
x*(25/30-24/30)=-5
x*1/30= -5
x/30=-5
x= -30*5
x= -150
