How do I calculate these division facts and what’s the answer 63 ÷ 7 56 ÷ 7
bixtya [17]

Answer:

63 divided by 7 is 9

56 divided by 7 is 8

Step-by-step explanation:

I don't really know how to explain it, because it's kind of complicated to do it how I answered it. I will try, but what you do is write out the equation using the little line division thing with the divisor and the dividend. First for 63 divided by 7, how many times can 7 go into 6? 0, so put a 0 on top of the 6. Then, minus 6 by 0, which is 6. Then, drop down the 3 in the ones place to where the difference of the subtraction problem is, which of 6. Then, we try to find a product that is 63 or close to 63 in a multiplication problem, and one of those factors has to be 7. 7 x 9 = 63, so put a 9 on top of the 3 at the beginning and minus 63 - 63, which is 0, meaning it has no remainder. Very hard to explain digitally, look up a video for help.

A rectangle has a height 3z and a width of 2x-3<br><br> Express the area of the entire rectangle.
viktelen [127]

Answer:

3z(2x - 3)

Step-by-step explanation:

Area of a rectangle, a = height * width

height, h = 3z

width, w = 2x - 3

a = 3z * (2x -3)

expand

a = 6xz - 9z

a = 3z(2x - 3)

Barry's final score is 45 which player had the greater final score?
natali 33 [55]

The player with the greater final score is of:

Barry.

<h3>How to obtain which player had the greater final score?</h3>

Barry's final score is given as follows:

45.

Then we have to obtain Lee's score, from the description given in the missing information section.

Lee's scored is obtained as follows:

  • Starts at -350.
  • Answers a 275-point question correctly, hence - 350 + 275 = -75.
  • Answers a 70 - point question correctly, hence -75 + 70 = -5.
  • Answers a 50 - point question incorrectly, hence: -5 - 50 = -55.

Thus Lee's final score is given as follows:

-55.

The classifications of the final scores according to the signals are given as follows:

  • Barry: positive score.
  • Lee: negative score.

A positive score will always be greater than a negative score, hence Barry had the greater final score.

<h3>Missing information</h3>

Lee and Barry play a trivia game in which questions are worth different numbers of points. If a question is answered correctly, a player earns points. If a question is answered incorrectly, the player loses points. Lee currently has -350 points.

a. Before the game ends, Lee answers a 275 -point question correctly, a 70 -point question correctly, and a 50 -polnt question incorrectly. Write and find the value of an expression to find Lee's final score.

b. Barry's final score is 45. Which player had the greater final score?
