Total: 22

(b) The actual total is $21.77 which rounds to $22, the same as the estimate, so the estimate is reasonable.

You are to round off all the dollar amounts given, and then to estimate the total bill using these rounded off figures.

So:  add up $3, $1, $5, $2, $3, $9, $1, -$1, -$1

Compare your result to the register sum, $21.77.

How close was your estimate to $21.77?  Justify your answer.

TERESA gave away 8 baseball cards and has 4 BASEBALL cards left. WRITE A subtraction problem tp show the fraction of he baseball
N76 [4]
Teresa gave away 8 baseball cards and has 4 left. 8 plus 4 means she originally had 12. Right now she has 4 out of her original 12 cards remaining. This gives us 4/12. We can simplify this by dividing our greatest common factors. 4 goes into both parts of our fraction, when we divide each part by 4 we end up with 1/3. Since we are unable to simplify this problem any further, this means our solution and fraction is 4/12 aka 1/3.

The coefficient of xy in the product of (4x^2+2y) and (3x+y^2) is ...
LUCKY_DIMON [66]
Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))
