What is the answer to this?

How is the total of these fractions: 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8 divided between 20 people?

Kamila [148]

1/8+ 1/4(2/8)+ 3/8+ 1/2(4/8)+ 5/8+ 3/4(6/8)+ 7/8= 28/8 = 3 1/2

If someone can answer all these ill give 100 points

Helga [31]

Answer:

1. x = -6

2. x = 2

3. x = 6

4. x = 3

5. x = -5

6. x = -1

7. x = 0

8. x = 9

9. x = -4

10. x = 7

Step-by-step explanation:

1.

$-10x = -8x + 12$

$-10x+8x=-8x+12+8x$
$-2x=12$

$-2x/-2=12/-2$
$x=-6$

2.

$9-5x+x=1-x+x$
$-4x+9=1$

$-4x+9-9=1-9$
$-4x=-8$

$-4x/-4=-8/-4$
$x=2$

3.

$-2x+16-x=x-2-x$
$-3x+16=-2$

$-3x+16-16=-2-16$
$-3x=-18$

$-3x/3=-18/-3$
$x = 6$

4.

$(-4)(6x)+(-4)(-2)= -8x-40$
$-24x+8=-8x-40$

$-24x+8+8x=-8x-40$
$-16x+8=-40$

$-16x+8-8=-40-8$
$-16x=-48$
$-16x/-16=-48/-16$
$x=3$

5.

$37 - 8x = (-7)(x)+(-7)(-6)$
$-8x+37=-7x+42$
$-8x + 37 + 7x = -7x + 42 + 7x$
$-x+37=42$
$-x+37-37=42-37$
$-x=5$
$-x/-1=5/-1$
$x=-5$

6.

$6x+(-2)(2)+(-2)(8x) = 10 + 4x$
$6x-4-16x = 10 + 4x$
$-10x - 4 = 4x + 10$
$-10x - 4 -4x=4x+10-4x$
$-14x-4=10$
$-14x-4+4=10+4$
$-14x=14$
$-14x/-14=14/-14$
$x=-1$

7.

$(-2)(x) + (-2)(1) = (2)(x) + (2)(-1)$
$-2x-2=2x-2$
$-2x-2-2x = 2x - 2 - 2x$
$-4x - 2 = -2$
$-4x-2+2=-2+2$
$-4x=0$
$-4x/-4=0/-4$
$x=0$

8.

$(-3)(x)+(-3)(3)=(-6)(x)+(-6)(-3)$
$-3x-9=-6x+18$
$-3x-9+6x=-6x+18+6x$
$3x-9=18$
$3x-9+9=18+9$
$3x=27$
$3x/3 = 27/3$
$x=9$

9.

$6x-36=(-4)(-2x)+(-4)(7)$
$6x-36= 8x -28$
$6x-36-8x = 8x - 28 - 8x$
$-2x-36=-28$
$-2x-36+36=-28+36$
$-2x = 8$
$-2x/-2=8/-2$
$x=-4$

10.

$(2)(x)+(2)(1) = -2x + 30$
$2x+2=-2x+30$
$2x+2+2x=-2x+30+2x$
$4x+2=30$
$4x+2-2=30-2$
$4x=28$
$4x/4=28/4$
$x=7$

10(a-2.5+0.56b) is this equivalent to 10a - 25+56b

kirill115 [55]

Hey there!

10(a - 2.5 + 0.56b)

= 10(a) + 10(-2.5) + 10(0.56b)

= 10a - 25 + 5.6b

= 10a + 5.6b - 25

Therefore, your answer is: 10a + 5.6b - 25

Good luck on your assignment and enjoy your day!

Three cards are dealt from a shuffled standard deck of playing cards. What is the probability that the three cards dealt are, in

Svetllana [295]

Answer:

The probability that the three cards dealt are, in order, an ace, a face card, and a 10 is $\frac{8}{5525}$

Step-by-step explanation:

Given : Three cards are dealt from a shuffled standard deck of playing cards.

To find : What is the probability that the three cards dealt are, in order, an ace, a face card, and a 10? (A face card is a jack, queen, or king.)

Solution :

Total number of cards - 52

Number of Ace = 4

Probability of getting an ace is $P_1=\frac{4}{52}$

Number of face cards = 12

Probability of getting a face card is $P_2=\frac{12}{51}$

Number of 10's = 4

Probability of getting a 10's is $P_3=\frac{4}{50}$

The probability that the three cards dealt are, in order, an ace, a face card, and a 10 is give by

$P=P_1\times P_2\times P_3$

$P=\frac{4}{52}\times \frac{12}{51}\times \frac{4}{50}$

$P=\frac{1}{13}\times \frac{12}{51}\times \frac{2}{25}$

$P=\frac{8}{5525}$

Therefore, The probability that the three cards dealt are, in order, an ace, a face card, and a 10 is $\frac{8}{5525}$
