After counting her weekly earnings, she bought a candy bar for $.45, a pen for 250 and her mom gave her 2.00. She had $5.05 left
horsena [70]

Answer:

She started with $6.00.

Step-by-step explanation:

1. This problem is meant to have you work backwards from the information given. Firstly, it is important to write all the expenses and earnings she had to her weekly earnings.

Starting Amount = ?

- $0.45 (candy bar)

- $2.50 (pen)

+ $.200 (mom)

End Total = $5.05

2. With this information, this next step will be much easier. With this process, you can now use inverse operations to undo the last few equations.

Firstly, $2.00 given by her mom will be subtracted from $5.05.

Secondly, with our new total of $3.05, $2.50 from purchasing the pen will be added to this amount. This leaves you with $5.55.

Lastly, the $0.45 cents she spent with the candy bar will be added to the $5.55.

This leaves the starting amount to $6.00.

3.  She started with $6.00

Step2247 [10]

Answer: it took them 7 hours to travel 49 miles.

Step-by-step explanation:

The exploratory scouts travel 32 miles in eight hours.

Speed = distance/time

It means that the speed at which they travelled 32 miles is

32/8 = 4 miles per hour.

The next day they had traveled 49 miles so they increase the speed by 3 mph. It means that the speed at which they travelled 49 miles is

4 + 3 = 7 mph

Time = distance/speed

Therefore, the time it took them to travel the 49 miles is

49/7 = 7 hours

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16
True [87]

Answer:

so x=5 1/3 and

y= -2 2/3

Step-by-step explanation:

x-3y= -2x+3y=16. First we need to move all variables to one side of the equation and whole numbers to the other side of the equation. I see

x-3y+2x-3y=16. -3y-3y equals to -6y. 2x+x=3x. so 3x-6y=16. Lets take out the -6y so our equation would be 3x=16. x would equal 5 1/3. Now lets put back -6y into our equation. Let's now substitute x as 0. 3 times 0 equals 0 so our equation would now be -6y=16 which equals to -2 2/3.

so x=5 1/3 and

y= -2 2/3
