Am getting the hang of this but I still need help so may I please get help with this equation -7a+6a^2-10

The factors are (a - 2) and (6a + 5) .If the expression is equal to zero, then 'a' can be 2, and 'a' can be -5/6 .
-7a+6a^2-10
I am assuming you are solving to get a zero, in which case a=2

In a relay race, the probability of the Galaxy team winning is 22%. In another unrelated relay race, the probability of the Komets team winning is 47%. If the possibility of a tie is not an option, the probability of the Komets losing their race and the Galaxy winning theirs is ?%

Answer: There is 12% chance that Komets losing their race and the Galaxy winning theirs.

Step-by-step explanation:

Since we have given that

Probability that Galaxy team winning = 22%

Probability that Komets team winning = 47%

Probability that Komets team losing = 100-47=53%

We need to find the probability of the Komets losing and Galaxy winning their game.

So, Probability that Komets losing and Galaxy winning their game is given by

Hence, there is 12% chance that Komets losing their race and the Galaxy winning theirs.

Fred bought seven adult and two student tickets for $16. John paid$7 for one adult and five student tickets. Individual costs are:

Adult ticket=$2 Student ticket=$1

Step-by-step explanation:

Let the cost of one adult ticket be $x and the cost of one student ticket be$y

Fred bought 7 adult and 2 student tickets for$16. So, 7x+2y=16. ...(1) And,John paid$7 for one adult and 5 student tickets.

So,

x+5y=7. ...(2)

From ...(2),

x=7-5y

Substituting the value of x in equation ...(1),

7(7-5y)+2y=16

or,49-35y+2y=16

or,33y=33

or,y=1

Now, substituting the value of y in ...(2),

x=7-5=2

Thus,the cost of one adult ticket is $2 and the cost of one student ticket is$1.
