Part A Ichiro bought a video game system on sale for $149 and 4 video games. Each video game costs the same amount, and he spent a total of $278
before tax on the system and games.
Which equation can be used to determine the cost c of each video game?
O A) 149 - 40 = 278
O B) 4(+149) = 278
O C) 4 + 149c = 278
O D) 149 + 40 = 278

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

i those same problems in math and dont know how to do them

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
