i.e.
---- in 28 places
Andre's interpretation of the expression is incorrect as:
Also, Elena's expression is incorrect.
This is so, because
<em>Hence, both of them are incorrect and I agree with none of them</em>
The answer D is not true.
Answer:
Below
Step-by-step explanation:
● f(x) = -2x + 3
● f (0) = -2 (0) +3 = 3
● f(-32) = -2(-32)+3 = 64 + 3 = 67
● f(10) = -2(10) +3 = -20 + 3 = -17
● f(-17) = -2(-17) + 3 = 34 + 3 = 37
● f(10) => -17
● f(-17) => 37
1 day = 1500 bricks
5 days = 1500 x 5
5 days = 7500 bricks
Answer (a) He would expect to lay 7500 bricks in a five day week.
1500 bricks = 8 hours
1 brick = 8/1500
10 000 = 8/1500 x 10 000 = 53 hours (nearest hour)
Answer: (b) It will take him 53 hours to lay 10000 bricks.
