Answer:
A. the first one is true because when x = 5, 4x - 1 equals 19. The second inequality doesn't allow for it to equal 19.
B. 9 is the value that makes the equation true. See below for work to show.
Step-by-step explanation:
4x -1 </= 19 is true because it's "less than or equal to" and when you change the x to 5, the answer is exactly 19. 4(5) - 1 = 19. The other sentence is "4x - 1 is less than 19", and that means it can't equal 19 for that sentence to be true.
Math + words = confusion sometimes. Does that make sense?
------------------------------------
Now let's solve
5x + 2 = 47
Subtract 2 from both sides
5x = 45
divide both sides by 5
x = 9

Answer: 12 lbs
Step-by-step explanation:
24x1/3= 8lbs ( used for fruit pies)
24-8= 16 lbs ( remainder)
16x 1/4= 4lbs ( for bread)
16-4 = 12 lbs remains
x = the granddaughter's age x + 2 = the grandson's age
x + x + 2 ≥ 12 Collect like terms.
2x ≥ 12 Divide both sides by 2.
x ≥ 6 years
x + 2 ≥ 8 years
