Question 1 (4 points)
If two numbers with the same sign are
or divided, the result is

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

2.14x - 12.18 = -5.76

add 12.18 to each side

2.14x -12.18 +12.18 = -5.76 +12.18

2.14 x =6.42

divide by 2.14

2.14x/2.14 = 6.42/2.14

x=3

write a system of equations to model the situation. add the equations to eliminate the y-term and then solve for x. substitute the value for x into one of the original equations to find y. check your answer by substituting x = 8 and y = 2 into the original system.

to figure out if an ordered pair is a solution to an equation, you could perform a test. identify the x-value in the ordered pair and plug it into the equation. when you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
