57.8 can be rounded to 60 because 57.8 is closer to 60 than 50 and 81 is relatively close to 80. if we had to estimate the quotient, we would have
60 ÷ 80 = 0.75
#8
2.8 can be rounded to 3 because 2.8 is closer to 3 than it is to 2 and 6 can be left alone because it will make our division easier.
3 ÷ 6 = 0.5
#11
737.5 can be rounded to 700 and 9 can be rounded to 10.
700 ÷ 10 = 100
Answer:
1). 875 seats
2). 25 rows in each section
3). $8400
4). Saving of $360
5). 2105 tickets remained unsold
6). x = 16
You begin dividing over the hundreds column, which is above the 9. Carry on from there, I hope this helps you!
101,473 - 9,879 = 91,594
91,594 + 9,853 = 101,447
101,447 is Will's score
This is a trial and error answer.
Suppose that QT = -3, then
x + 2 = y
2x = y + 3
Apply substitution,
2x = (x+2) + 3
2x = x + 5
x = 5
y = 7
chek your answer,
x + 2 = y
<span>5 + 2 = 7</span>
