Answer: The total amount the water change was -28 gallons by the end of the week <u>OR</u> The total amount the water changed decreased 28 gallons by the end of the week. Depending on how you want to word it.
Hope this helps!
Step-by-step explanation:
<u>Create you equation:</u>
x = the total amount the water changed
d = the amount of days
x = -4d
<u />
<u>Insert the known information into the equation and solve:</u>
x = -4d
x = -4(7)
x = -28
Let x = software program
Let y = video game
x < 200 ; y < 300
x + y < 425
50x ; 35y
x = 200 ; y = 225
50(200) + 35(225) = 10,000 + 7,875 = 17,875
x = 125 ; y = 300
50(125) + 35(300) = 6,250 + 10,500 = 16,750
x = 175 ; y = 250
50(175) + 35(250) = 8,750 + 8,750 = 17,500
It is more profitable to maximize production of software program when working within the limits provided.
Answer:
D
Step-by-step explanation:
Here, we want to know which of the options would be true if we replace the term in the box ( D) by the value 1,537.
The correct option here is thus D
What we have here would be
1537 > 1,357
This can be read as 1537 is greater than 1,357 which is correct
The answer is 4 (136y-21)
Explanation:
Factor 4 out of 544y.
4 (136y) - 12*7
Factor 4 out of -12*7.
4 (136y) + 4 (-3*7)
Factor 4 out of 4.
(136y) + 4 (-3*7)
4 (136y- 3*7)
Multiply -3 by 7.
4 (136y - 21)
<u>Answer:</u>
<u>Step-by-step explanation:</u>
To find the solution to the equation, we have to rearrange the equation to make
