1) billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. billy had 5 practices last week. how many yards did billy walk last week to practice. 1760 yards 2) marks age is, t, is 3 times his age 10 years ago. write an equation to represent the statement

1 )  Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that,  1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be:

2) Mark's current age is years

So, his age was in 10 years ago

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be :  

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
