-4-4-4+9 = -3
so, they wound up with a loss of 3 yards
or, 3(-4)+9 = -3
for the sub, you want
-125 + 3(-50) = -125-150 = -275
Your setup yields -125(-150) = 18750 ft in the air!
220-4(35)
or, 220+4(-35)
Your final answer is correct, though, which shows that you not only don't know how to set up the expression, you do not know how to evaluate it once written!
You have an extra minus sign.
I have 2 problems and 1 problem to check on.
Write a mathematical expression to represent each situation. Then find the value of the expression to solve the problem.
#1 A football team loses 4 yards on each of three plays. Then they complete a pass for 9 yards. What is the change in yardage after those four plays?
I don't know how to do this problem, I don't know how to write the expression for this as well. For now I have -4, 3, and 9. What do I do with these integers ?
#2 A submarine is at -125 feet in the ocean. The submarine makes three dives of 50 feet each. At what level is the submarine after the three dives?
My expression for this is -125(3 * -50), is this correct?
#3 You have $220 in your savings account. You take $35 from your account each week for four weeks. How much is left in your account at the end of the four weeks?
I got $220 - ($-35 * 4) $80 is left in my account after 4 weeks. Is this correct?
Thank you~
Sorry if I made mistakes, I'm in a rush
