Can anybody tell me how to solve this

Lyrx [107]

The answer to your question is: Yes, someone undoubtedly can.

Although you haven't asked to be told or shown how to solve it, I'm here
already, so I may as well stick around and go through it with you.

The sheet is telling you to find the solutions to two equations, AND THEN
DO SOMETHING WITH THE TWO SOLUTIONS. But you've cut off the
instructions in the pictures, so all we have are the two equations, and
you'll have to figure out what to do with their solutions.

First equation:
 (2/5) x - 6 = -2
Add 6 to each side:
 (2/5) x = 4
Multiply each side by 5:
 2x = 20
Divide each side by 2 :
 x = 10

Second equation:
 -3y + 1/4 = 13/4
Subtract 1/4 from each side:
 -3y = 12/4
Multiply each side by 4 :
 -12 y = 12
Divide each side by -12 :
  y = -1

Shaquana finds some nickels and pennies in her change purse. How much money (in

kupik [55]

Answer:

3.50$

Step-by-step explanation:

Since a nickel is 5 cents, you would do 5 x 60 which would equal 300, which is 3 dollars.

Since a penny is worth 1 cent, you would do 1 x 50 and get 50 cents, which is half a dollar.

3 + .5 = 3.50

Hope this helps!

A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same

creativ13 [48]

Answer:

The speed is inversely proportional to the time when the same distance is traveled.

Step-by-step explanation:

Given that:

The distance traveled by the biker in 8 hours is 120 mi.

The speed of the biker=120/8=15 mi/hr.

[as speed=Distance travelled/Time taken]

As all take the same route, so the distance traveled by all is the same which is 120 mi

The time taken by the bus to cover this distance is 2 hours.

So, the speed of the bus = 120/2=60 mi/hr.

The time taken by the truck is 2.5 hours.

So, the speed of the truck = 120/2.5=48 mi/hr.

And the time taken by the rider is 18.75 hours.

So, the speed of the rider = 120/18.75=6.40 mi/hr.

Now, observe that to cover the same distance, the bus takes the least time, so, the bus is traveling at the fastest speed among all, while the rider has the slowest speed as the distance is the same for all. The truck and the biker have speed in between the speed of the bus and the rider.

It can be concluded that when the time of the journey for the same distance is less than speed is more.

So, the speed is inversely proportional to the time when the same distance is traveled.

Or, $\text{Speed}\propto\frac{1}{Time}$
