Like I said above, There were 40 rolls, 6 of which were a two (6/40) and 8 of which were a 4 (8/40). Simply add these together to get 14/40 as the probability of rolling a 2 or 4. This simplifies to 7/20
6x+1(3x-12)=6
6x+3x-12=6
9x-12=6
+12= 18/9 x=2
Y=6-12
Y=-6 (2,-6
Answer:
D
Step-by-step explanation:
For example,
5×7-10>20
5(-3)-10<15
Step-by-step explanation:
7 + x/3 =2x - 5
7 + 5=2x - x/3
12 = 5x/3
cross multiply
36=5x
x=36/5
x=7.2
