Let the slower runners speed be X kilometers per hour.

Then the faster runners speed would be X+2 kilometers per hour.


The formula for distance is Speed times time.

The distance is given as 30 kilometers and time is given as 3 hours.


Since there are two runners you need to add the both of them together.

The equation becomes 30 = 3x + 3(x+2)

Now solve for x:

30 = 3x + 3(x+2)

Simplify:

30 = 3x + 3x +6

30 = 6x + 6

Subtract 6 from each side:

24 = 6x

Divide both sides by 6:

x = 24/6

x = 4


The slower runner ran at 4 kilometers per hour.

The faster runner ran at 4+2 = 6 kilometers per hour.

Johanna has to solve the system of equations using substitution. She isolates x in the second equation. Which should be her next
olganol [36]

Answer: A) 3(10 - 5y) + 6y =12

Step-by-step explanation:

As per the question , the given system of linear equation :

3x+6y=12---(i)\\\\ x+5y=10---(ii)

Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes

x=10-5y

As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become

3(10-5y)+6y=12

Hence, the correct option is A) 3(10 - 5y) + 6y =12

Tory is solving the equation shown correctly in her notebook, but the paper gets smudged, and she cannot read the last few lines
elena55 [62]

This question is incomplete because the options are missing. Here are the options:

A. - 4 = 5x

B. -4 = x

C. -4 + x = 0

D. -4 + 5x = 0

The correct next line of the solution is A. -4 = 5x

An equation is:

  • A mathematical expression that represents mathematical equality between two expressions.
  • It has two expressions and is separated by the equal sign, called members.
  • It has known elements and unknown or unknown data represented with letters like x

According to the above, it can be inferred that the correct answer is option A. because it expresses the correct values according to the operations that have been carried out in the previous lines.
