If you can pick it up with your fingers or one hand - grams.
If you can move it about, and maybe load it on a truck by yourself - kilograms.
If you can’t even budge it without help - tonnes.
Yes, (1,7) is a solution.
(x,y)
y < x + 8
y ≤ 6x + 1
7<1+8 = 7<9 Yes, true.
7≤6(1)+1 = 7≤ 7 Yes, true.
Yes, (1,7) is a solution to the inequalities.
50mph, 60 minutes, half both 25 and 30
A-B should be 30 minutes
B-C should probably be 20-25 personally I'd go with 25
so 55?
Answer:
its a ...............................
2(4x+5)>7x+20 perform indicated multiplication on left side
8x+10>7x+20 subtract 7x from both sides
x+10>20 subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
