Answer:
D
Step-by-step explanation:
The answer is D, because when you divide x by a negative the sign changes
75x + 90(15-x)=88(15)
75x+1350-90x = 1320
-15x + 1350 = 1320
-15x= -30
x=2
the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons
Hope this helps.
Answer:this one is hard
Step-by-step explanation:
Answer:
7/9
Step-by-step explanation:
P(blue) = 2:7
This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.
P(not blue) = 1 - 2/9
= 7/9
Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
