Jaime is at a library that is 5 miles from her house. Her brother, Max, is at a rec center that is 4.5 miles from the house. The library and rec center both close at 6:00 p. m. Jaime and Max are beginning their training for soccer, so they decide to run home. Jaime maintains a constant rate of 8 miles per hour, while Max runs at a constant rate of 7.5 miles per hour. Which system of equations correctly represents these situations where d is the distance from home in miles and t is the length of time in hours?

{d=−8t−5d=−7.5t−4.5
{d=8t−5d=7.5t−4.5
{d=8t+5d=7.5t+4.5
{d=−8t+5d=−7.5t+4.5

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

answer by jkismyhusbandbae:

a) how close a measured value is to the actual (true) value.

  measure of length.   there are 12 inches in a foot, and 36 inches in a yard.   one inch is exactly 2.54 centimeters.

accuracy is how close something is to an actual answer but it is not exactly correct.

answer: the right triangle the furthest one on the right
