Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
X - y = 3
x + y = 13
Adding both equations
2x = 16
x = 8
y = 5
The x-intercept is (9,0). Hope it help!
9.32x10.3= 12116
3.32x10.2=3984
16100
