4/10 because 4/10 plus 2/10 = 6/10 and that leaves her 4/10 of the book left hope she likes the book :D
If you multiply your fist equation by 2 you'll be able to cancel out your y's and solve for x and find that x is -2 making D the right answer.
The answer is 105160 because five or more up the score, four or less let it rest
Answer:
z = 50.2802734375
Step-by-step explanation:
y = 15.5
y is 512 times x
z is 50.25 more than x
15.5/512 = 0.0302734375
x = 0.0302734375
0.0302734375 + 50.25 = 50.2802734375
z = 50.2802734375
