- 40 ≥ 8 b
switch sides:
8b ≤ - 40
divide both sides by 8 :
8b / 8 = - 40/8
refine:
b ≤ - 40 / 8
b ≤ - 5
hope this helps!
19. There are 24 hours in a day and Maria travelled for 15 days so multiply the two:
24*15=360
So Maria travelled for 360 hours.
22a. False; 2,000 lbs = 1 Ton
22c. True; 48 oz = 3 lbs
<span>A) 5x + 7y = 3
B) 2x + 3y = 1
Multiplying Equation B by -2.5
</span><span>B) -5x -7.5y = -2.5 Then adding this to Equation A)
A) 5x + 7y = 3</span>
-.5y = .5
y = -1
Since
<span>2x + 3y = 1 then
2x -3 = 1
then x = 2

Sachi5, to find the sum of 24, 36, and 13 you would simply add 24+36. this will give you 60. Now we add 13 to 60 to get our sum of 73.
