Answer:
D
Step-by-step explanation:
Options A & B are multiplied by improper fractions. Therefore,
54 × (5/3) > 54 not < 54
28 × (3/2) > 28 not < 28
Option C should be 49 × (3/7) < 49 not > 49
Whole numbers multiplied by fractions should be smaller.
Hence, option D is the right answer.
Note: Try multiplying like this
(54×5)/3 _ 54
(28×3)/2 _ 28
(49×3)/7 _ 49
(140×2)/5 _ 140
Answer:
x = -4
Step-by-step explanation:
Notice that the two points given, share the same x-value even when the y-value changes. This is because the equation is going to be a vertical line at -4 on the x-axis. Being a vertical line, you cannot take its slope using the slope formula of: <em>m = (y2 - y1) / (x2 - x1)</em> because the denominator will result in a 0 and you cannot divide by 0 in mathematics.
Answer:
46 yards
Step-by-step explanation:
let x = number of lawns mowed per month
let y = number of full landscape maintenance service
y = 2x
100x + 130y = 8,280
100x + 260x = 8,280
360x = 8,280
x = 8,280 / 360 = 23
Melissa provides only lawn service to 23 yards and full landscape maintenance service to 46 yards.
Answer: Place the runners into groups based on the seconds part of their finishing time (0:00–0:05, 0:06–0:10, etc.). Randomly select 2 of these groups, and survey every runner within the chosen groups.
