Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles until he reaches a total of 26 m

sergejj [24]

Answer:

$1.5x+12=26$

Step-by-step explanation:

Let x be the number of weeks that it will take Andy to reach his goal.

We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

$1.5x+12=26$

Therefore, the equation $1.5x+12=26$ can be used to determine x, the number of weeks that it will take Andy to reach his goal.

Well there is to equations here that must be equal. X+20=4X Four times old means 4X+X=5X.

If you work to simply the problem you get something that looks like this:
X+20=5X
20=4X
x=20/4 or 5 y/o!
