Answer:

v = -16

Step-by-step explanation:

<u>→Distribute the 5 to (-7v - 11):</u>

14 - 10v + 11 = 20v - 35v - 55

<u>→Add like terms:</u>

25 - 10v = -15v - 55

<u>→Add 15v to both sides:</u>

25 + 5v = -55

<u>→Subtract 25 from both sides:</u>

5v = -80

<u>→Divide both sides by 5:</u>

v = -16

Answer:

\boxed{v =  - 16}

Step-by-step explanation:

=  > 14 - 10v + 11 = 20v + 5( - 7v - 11) \\  \\  =  > 14  + 11 - 10v = 20v + (5 \times ( - 7v)) - (5 \times 11) \\  \\  =  > 25 - 10v = 20v - 35v - 55 \\  \\  =  > 25 - 10v =  - 15v - 55 \\  \\  =  > 25  - 10v + 15v =  - 55 \\  \\  =  > 25  + 5v =  - 55 \\  \\  =  > 5v =  - 55 - 25 \\  \\  =  > 5v =  - 80 \\  \\  =  > v =  -  \frac{80}{5}  \\  \\  =  > v =  - 16

20 years ago, father's age was 5 times his son's age. Now his age is 10 years more than twice his son's present age. Find their
Montano1993 [528]

Step-by-step explanation:

x = father's age now

y = son's age now

x = 2y + 10

x - 20 = 5(y - 20) = 5y - 100

using the first in the second equation :

2y + 10 - 20 = 5y - 100

-10 = 3y - 100

90 = 3y

y = 30

x = 2y + 10 = 2×30 + 10 = 60 + 10 = 70

the father is now 70 years old, the son now 30 years old.

The current in a simple electric circuit varies inversely as the resistance. If the current is 20amps when the resistance is 5 o
IrinaVladis [17]

Answer:

0.5amps

Step-by-step explanation:

I is inversely proportional to resistance

I = k/R

k = I/ R

k = 20/5

k = 4

This means that, I = 4/R

So, when R = 8ohms,

I = 4/8

 =0.5amps
