Answer:

<h2>0.67</h2>

Step-by-step explanation:

5(y - 3.8) = 4.7(y - 4)

Distribute 5 through the parentheses

5y - 19 = 4.7(y - 4)

Distribute 4.7 through the parentheses

5y - 19 = 4.7y - 18.8

Move ' 4.7 y ' to L.H.S and change it's sign

5y - 4.7y - 19 =  - 18.8

Move constant to R.H.S and change it's sign

5y - 4.7y =  - 18.8 + 19

Collect like terms

0.3y =  - 18.8 + 19

Calculate

0.3y = 0.2

Divide both sides of the equation by 0.3

\frac{0.3y}{0.3}  =  \frac{0.2}{0.3}

Calculate

y = 0.67

Hope this helps...

Best regards!!

Answer:

y = 0.67   (To 2 dps)

y = 0.7 (To 1 dps)

y = 1 (To nearest whole no.)

Step-by-step explanation:

5(y-3.8) = 4.7 (y-4)

Distribute the terms

5y - 19 = 4.7y-18.8

Combining like terms

5y - 4.7y = -18.8+19

Adding and subtracting

0.3y = 0.2

Dividing both sides by 0.3

y = 0.2/0.3

y = 0.67

Your new job is 25 miles away from your house. If you drive to work at a rate of 50 miles per hour, how long does it take you to
sergeinik [125]

the time taken to get to your work place is 0.5 hour.

The given parameters;

  • distance between  your new job and your house  = 25 miles
  • speed to work, v = 50 mph

The time taken to get to work is obtained by dividing  the distance between your new job and your house, by speed of your motion to work.

Distance = speed x time

Time = \frac{Distance }{speed} \\\\T ime = \frac{25}{50} \\\\Time = 0.5 \ hour

Thus, the time taken to get to your work place is 0.5 hour.

Seth has just decided to replace his computer. His old computer cost him $1,433 when he bought it exactly seven years ago. Seth
puteri [66]

Answer:

The answer is D

Step-by-step explanation:

The solution would be like this for this specific problem:

Cost of the computer:

i = 0.117 / 12 

i = 0.00975 

= monthly payment 

= (i * P * (1 + i)^n) / ((1 + i)^n - 1) 

= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1) 

= $55.32 

Electricity cost:

= $0.79 * 365.25 * 7 

= $2019.83 

Electricity Percentage: 

= $2019.83 / ($2019.83 + $1659.60) 

= 54.89% 

Electricity: 

= ($0.79 * 365 * 5) + ($0.79 * 366 * 2) 

= $2020.03 

 

Electricity Percentage: 

= $2020.03 / ($2020.03 + $1659.60) 

= 54.898%

In total, the electricity made up 54.898% of the lifetime cost of the computer.

Trava [24]

Answer:

If 2 mph) 5 hours

If 2.5 mph) 4 hours

If m mph) 10/m hours

If m+2 mph) 10/(m+2) hours

If m/3 mph) 30/m hours

Step-by-step explanation:

To find the time divide the distance (10) by the speed.

10/2=5

10/2.5=4

10/m

10/(m+2)

10/(m/3)=10(3/m)=30/m
