77.5d + .14m
m = 425
.14 * 425 = 59.5
77.5d + 59.5 ≤ 230
77.5d ≤ 170.5
d ≤ 170.5/77.5
d ≤ 2.2

Answer:0,3 and 3,0
Step-by-step explanation:
0,3 and 3,0 are right because we need 0 and 3 to be one the X side
1,0 and -1,3 is wrong it is not a 1 or -1
2,0 and 2,0 is wrong because it is not 2 on x axis
-1,0 and -1,-3 are wrong because we are not on -1 on x axis
hopefully i explained it right
So i think this wan being
(8,1 x 10^5)
----------------- = 0,9 x 10^3 = 9 x 10^2
(9 x 10^2)
<span>n = 9 * 27 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Firstly do the multiplications and divisions, then additions and substractions.
Hope I could help :)</span>
