Answer:

1) x= -2

2) x= 3

3) x=7

4) x>5

5) x=-14

Step-by-step explanation:

1) −3x − 3 −7x = 17

−10x−3=17

−10x=17+3

−10x=20

x= -20/10

x=-2

2) 10x − 6 = 24

10x=24+6

10x=30

x= 30/10

x= 3

3) −4−5x=−39

−5x=−39+4

−5x=−35

x=-35/-5

x= 7

4) 3x - 5 > 10

3x>10+5

3x>15

x>​15/3

x>5

5)  -5 + x + 16 = -3

x+11=−3

x=−3−11

x=-14

Keith_Richards [23]

Answer:

1.19685 × 10¹⁶

Step-by-step explanation:

From the given information.

Since each players receives 5 cards; then = 5 * 4 = 20

Now, the process to go about this is to first select 5 cards out of 24 that goes to player 1. Then from the remaining 19, we can select another 5 cards that goes to player 2, etc. until 4 cards are left, out of which one is remained faced up. Thus, the 4 sets of 5 cards selected can be shuffled in 4! ways.

∴

No fo ways = ^{24}C_5 \times ^{19}C_5 \times ^{14}C_5 \times ^{9}C_5 \times 4! \times ^{4}C_1

= \dfrac{24!}{5!(24-5)!}\times  \dfrac{19!}{5!(19-5)!}\times  \dfrac{14!}{5!(14-5)!}\times  \dfrac{9!}{5!4!}\times 4! \times \ \dfrac{4!}{1!(4-1)!}

= \dfrac{24!}{5!^4}\times 4

= 1.19685 × 10¹⁶

<em>4*5= 20 </em>

<em>8*5=40</em>

<em>12*5=</em><u>  60</u>

Can someone help me with this?<br> I am not understanding this and the diagram<br> Thanks
Pavel [41]

Answer:

a) m∠FGH= 28°

b) m∠HGI =  28°

c) m ∠FGI =  56°

Step-by-step explanation:

GH bisects ∠FGI. So, ∠FGH = ∠HGI

    5x - 2   = 6x -8

     5x - 6x = 2 - 8

              -x = - 6

               x = 6

a) m∠FGH = 5x - 2 = 5 * 6 - 2 = 30 - 2 = 28°

b) m∠HGI = 6x - 8  = 6 * 6 - 8  = 36 - 8 = 28°

c) m ∠FGI = m∠FGH + m∠HGI = 28° +28° = 56°
