Answer:
Option B is correct
It must be a positive number since it represents a number of hours.
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
__________________________________________________________
Given the equation as:
Using distributive property,
Combine like terms;
Subtract 40 from both sides we have;
Divide both sides by -8 we have;
h = 14 hours
__________________________________________________________
Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
(4/5) 60 = 48 potatoes only, filled in correctly in the box
(1/5) 60 = 12 beets only; put that in the rightmost box
That leaves 40 for the middle, both potatoes and beets.
Answer: fill in the boxes 48 40 12
X= -3B + 2A
= [ 9 21 ] + [ 8 -2 ]
-21 -3 10 4
comparing the corresponding elements,
X= [ 9+8 21-2]
-21+10 -3+4
X= [17 19 ]
-11 1
Answer:
Step-by-step explanation:
-4 < x ≤ 1
