Answer:
d1 = 192
d2 = 192
Step-by-step explanation:
step 1
From the imformation given, the distance is the same
so from the table
d1 = 64t
d2 = 48(7-t)
the distance is the same, it means
d1 = d2
therefore we can get the time(t) from here
64t = 48(7-t)
64t = 336 - 48t
collect like terms
64t+48t = 336
112t = 336
t = 336/112
t = 3
substitute t into d1 to get the distance
d1 = 64t
d1 = 64 × 3
d1 = 192
Note, d1 = d2
d2 = 192 too
Answer is b
4000/12 = 333
333+80 = 413
413*20= 8260 they have enough
400/12=333
333*22= 7326 not enough

Answer:
OPTION A
Step-by-step explanation:
4(0.5x+2.5y-0.7x-1.3y+4)
2x + 10y-2.8x-5.2y+16
-0.8x +4.8y +16
