1/4 (8× - 4) = 5x + 8​

Answers

Answer 1
Answer:

Answer:

x = -3

Step-by-step explanation:

What you do is get x by itself.

1/4(8x - 4) = 5x + 8 Distribute 1/4 to 8x and -4.

2x - 1 = 5x + 8 Subtract 5x on both sides.

-3x -1 = 8 Add -1 to both sides.

-3x = 9 Divide -3 on both sides.

x = -3
Answer 2
Answer:

Answer: - 3

Step-by-step explanation:

Expand the brackets

It will give: 2x - 1 = 5x + 8

Collect like terms: 2x - 5x = 1 + 8

- 3x = 9

Divide both sides by - 3

x = -3

As students walk into Mr. Jackson's class, they are randomly handed either a blue, yellow, green, or red card. If there are 8 boys and 12 girls in the class, what is the probability that the student chosen by Mr. Jackson will be a boy with a green card?A. 1/8  B. 1/16  C. 2/15 D. 1/5

Answers

we are given

Event-A:

they are randomly handed either a blue, yellow, green, or red card

so, total number of cards =3

probability of selecting green cards = (number of green card)/(total number of cards)

probability of selecting green cards is (1)/(3)

Let's assume

p(A)=(1)/(3)

Event-B:

there are 8 boys and 12 girls in the class

total number of students =8+12=20

number of boys =8

probability of a boy = (number of boys)/(total number of students)

p(B)=(8)/(20)

Since, events A and B are independent

so,

probability that the student chosen by Mr. Jackson will be a boy with a green card = p(A)*p(B)

probability that the student chosen by Mr. Jackson will be a boy with a green card = (8)/(20) *(1)/(3)

=(8)/(20) *(1)/(3)

=(2)/(15)

probability that the student chosen by Mr. Jackson will be a boy with a green card is (2)/(15)...........Answer
the answer is B 1/16 there are 16 kids in total 

75% of what number is 27?

Answers

So we want to know the number from which we take 75% and get 27. If the number we are looking for is x, then the equation to find that x would be: (75/100)*x=27 which says seventy five percent out of x is equal 27. So, x=(27*100)/75. And finally, x= 2700/75=36. So, 75% out of 36 is 27.
