Answer:
0.5
Step-by-step explanation:
P(grape or straw) = P(grape) + P(straw) − P(grape and straw)
P(grape or straw) = 0.3 + 0.3 − 0.1
P(grape or straw) = 0.5
Answer:
x=6/5 or 1.2
Step-by-step explanation:
I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both
2= -5x+8 (next subtract 8 from both sides)
-6= -5x (divide both sides by -5)
-6/-5=x (the negative cancel out next)
6/5 or 1.20 is x
If your original problem should say 2x=-5x+8
2x=-5x+8 (add 5x to both sides next)
7x=8 (divide by 7 on both sides)
x=8/7
