-3(w+12)-11w=5 how to solve this problem
Trava [24]

Firstly, foil -3(w + 12): -3w-36-11w=5

Next, combine like terms: -14w-36=5

Next, add 36 on both sides of the equation: -14w=41

Lastly, divide both sides by -14, and <u>your answer will be w=-\frac{41}{14}, or approximately (rounded to the hundreths) -2.93.</u>

Emily wins 22000$. She has to pay 10% for charity and then she decides to buy a car for 10800$. She divides the rest of them bet
devlian [24]

Answer:

$7 200

Step-by-step explanation:

Amount of money paid for charity = \frac{10}{100} × $22 000

                                                         = $2 200

Remaining money left for children = $22 000 - $2 200 - $10 800

                                                         = $9000

Let the amount of money her son receives be x and the amount her daughter gets be 4x.

Son's $ + Daughter's $ = $9000

x + 4x = 9000

5x = 9000

Amount of money her daughter gets (4x) = \frac{4}{5} × 9000

                                                                     = $7 200

Mrs. Braddock has a bag containing 6 lipsticks, 4 eye shadows, 6 eye liners, and 5 mascaras. She will randomly choose one item f
Slav-nsk [51]

Answer:

The probability that she will not pull lipstick is 71%.

Step-by-step explanation:

The probability of an event <em>E</em> is the ratio of the favorable number of outcomes to the total number of outcomes.

P(E)=\frac{n(E)}{N}

Here,

n (E) = favorable number of outcomes

N = total number of outcomes

The contents in Mrs. Braddock's bag are:

Number of lipsticks = n (L) = 6

Number of eye shadows = n (S) = 4

Number of eye liners = n (E) = 6

Number of mascaras = n (M) = 5

Total number of items in the bag = N = 21

Consider that the probability of an event occurring is P. Then the probability of the given event not taking place is known as the complement of that event.

Complement of the given event is, 1 – P.

Compute the probability of selecting a lipstick as follows:

P(L)=\frac{n(L)}{N}\\\\=\frac{6}{21}\\\\=\frac{2}{7}

Compute the  probability of not selecting a lipstick as follows:

P(L^{c})=1-P(L)

          =1-\frac{2}{7}\\\\=\frac{7-2}{7}\\\\=\frac{5}{7}

Convert this probability into percentage as follows:

\frac{5}{7}\times 100 = 71.4286\approx 71\%

Thus, the probability that she will not pull lipstick is 71%.
