What does the variable represent in the equation 6-8p=38

GalinKa [24]

Solving the equation $6-8p=38$ we get value of p = -4

Step-by-step explanation:

We need to find the value of p in the equation $6-8p=38$

Solving to find value of p:

$6-8p=38\\Adding\,\,-6\,\,on\,\,both\,\,sides:\\6-8p-6=38-6\\-8p=32\\Divide\,\,both\,\,sides\,\,by\,\,-8\\\frac{-8p}{-8}=\frac{32}{-8}\\p=-4$

So, solving the equation $6-8p=38$ we get value of p = -4

the number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has.in total,the

Alexeev081 [22]

Assume the following:

Brad has been in the soccer team for b years.

Scot has been in the soccer team for s years.

"The number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has"

means: b=5s-2

"in total,the boys have been on the soccer team for 10 years."

means: b+s=10

so we have the equations:

i) b=5s-2

ii) b+s=10

substitute b in ii) with 5s-2, as they are equal, from i

(5s-2)+s=10

5s-2+s=10

6s=12

s=2,

then , from b+s=10, b=8

Answer: Brad has been in the team for 8 years.
