Answer:

x = -5

Step-by-step explanation:

4 - 2(x+7) = 3(x+5)

4 - 2*x - 2*7 = 3*x + 3*5

4 - 2x - 14 = 3x + 15

4 - 14 - 15 = 3x + 2x

-25 = 5x

x = -25/5

x = -5

Check:

4 - 2(-5+7) = 3(-5+5)

4 - 2*2 = 3(0)

4 - 4 = 0

Answer:

x = -5

Step-by-step explanation:

4-2(x+7)=3(x+5)

Distribute

4 -2x-14 = 3x+15

Combine like terms

-2x-10 = 3x+15

Add 2x to each side

-2x-10+2x= 3x+15+2x

-10 = 5x+15

Subtract 15 from each side

-10-15 = 5x+15

-25 = 5x

Divide by 5

-25/5 = 5x/5

-5 =x

Answer:

v = 3 , 3/5

Step-by-step explanation:

$5 {v}^{2} - 18v + 9 = 0 \\ 5 {v}^{2} - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v = \frac{3}{5}$

If the probability is 0.54 that Stock A will increase in value during the next month and the probability is 0.68 that Stock B wi

Aloiza [94]

P(A) =0.54

P(B)= 0.68

P'(A)= 1-0.54 = 0.46

P'(B)= 1- 0.68 = 0.32

The probability of neither of both event will occur:

= P'(A)×P'(B)

=0.46 × 0.32

=0.1472
