Answer:
x=2.7142 y=-2.8571,
Step-by-step explanation:
given 4x-8y=12............(1)
14+2x=-6y
2x+6y=-14..........(2)
from equ (2) multiply by 2
4x+12y=-28............(3)
substruct (1) and (3)
4x-8y-4x-6y=12-(-28)
-14y=40 ,y=
=-2.8571
y=-2.8571 put in equ (1)
4x-8(-2.8571)=12
4x=12-22.857=10.8571
x=
x=2.7142
Answer:
Okay, gimme a sec...
Step-by-step explanation:
Answer:
12 days
Step-by-step explanation:
Set up an equation with y = mx + b, where m is the rate and b is the y-intercept (starting value)
Let x represent how many days it takes and y represent how many pages he read:
445 = 24x + 157
Solve for x:
288 = 24x
12 = x
So, it will take him 12 days to finish the book
