Answer:

x = -516

Step-by-step explanation:

(4 - 5x) + 43 = 3 - 32(-82) {Multiply 32 and (-82)}

4 - 5x + 43 = 3 - (-2624)

4 - 5x + 43 = 3 + 2624 {add 4 and 43 in LHS}

-5x + 47 = 2627 {Subtract 47 from both sides}

-5x = 2627 - 47

-5x = 2580 {Divide both sides by (-5)}

x = 2580/(-5)

x = -516

37. The sum of first three terms in an arithmetic progression is 24 and the sum of their squares is 224. Find the first three te

Airida [17]

Answer:

12, 8, and 4

Step-by-step explanation:

Given

a + d + a + a - d = 24

3a = 24 ⇒ [ a = 8 ]

and (a + d)² + a² + (a - d)² = 224

3a² + 2d² = 224

2d² = 224 - 192 = 32

d² = 16

[ d = ±4 ]

∴ The first three terms to A.P are

a + d = 8 + 4 = 12

a - = 8

a - d = 8 - 4 = 4

∴ Three terms are 12 , 8, and 4

- 1/3 x + 12 = -2x + 2 ?

Vikentia [17]

Answer:

x = -6

Step-by-step explanation:

- 1/3 x + 12 = -2x + 2

(- 1/3 x + 1/3) + 12 = (-2x + 1/3) + 2

12 = - 1 2/3x + 2

12 -2 = - 1 2/3x (+ 2 - 2)

10 = - 1 2/3x

x = -6

Macy is playing with a standard deck of fifty-two playing cards. She selects one card at random from the deck. What is the proba

olasank [31]

Answer:

The probability that the card is an ace is $\frac{1}{13}$

Step-by-step explanation:

Total number of playing cards = 52

Total number of ace cards = 4

She selects one card at random from the deck.

We are supposed to find the probability that the card is an ace

So, Probability of getting card= $\frac{\text{No. of ace cards}}{\text{Total no. of cards}}$

Probability of getting card= $\frac{4}{52}=\frac{1}{13}$

Hence the probability that the card is an ace is $\frac{1}{13}$
