Simplify 10x + 7y + 32x - 15y please help!

Drag a statement or reason to each box to complete this proof.

Vadim26 [7]

The items below show the complete steps as to how this is being answered.

1. 3x - 4 = 14 >>>> Given
2. 3x - 4 + 4 = 14 + 4 >>>
Step number 2 above is an addition property of equality. Both sides of the equation are added with 4.
3. Simplifying >>>
3x = 18
4. 3x/3 = 18/3 >>>> Division property of equality
5. >>>> Simplifying,
x = 6

Hence, the order of the choices as answers is C, E, B, A, D.

If x - 12y = -210 and x - 6y = 90, then x =

Annette [7]

X=-198(substitute the value of x into the equation)
x-6y=90

-198-6y=90(solve the equation)

y=-48(a possible solution is)

(x,y)=(198,-48). (check yhe solution)

-198-12= 210(simplify)
-198-6(-48)=90

-210=-210( the ordered pair is a solution)
90=90

(x,y)=(198,-48)
is the answer

The probability that a certain hockey team will win any given game is 0.3773 based on their 13 year win history of 389 wins out

notsponge [240]

Answer:

0.8895 = 88.95% probability that the hockey team wins at least 3 games in November.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the teams wins, or they do not win. The probability of the team winning a game is independent of any other game, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
