The answer is 12 because if you roll it twice the possibility is 12
1) Add 9 to both sides
2) You get 15y<45
3) Divide by 15 on both sides
4) You get y<15
Remember that < is less than and > is greater than
Also note that when you divide by a negative number, you need to flip the inequality symbol.
The answer is x=6 and y=4.
6+4=10
and 8 times 6 + 12 times 4 is 96.
There is no y in this question, however we can solve for t.
1.4t - 0.4(t - 3.1) = 5.8
1.4t - 0.4t + 1.24 = 5.8
t + 1.24 = 5.8
t = 4.56
