1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?
[ Triple the quantity of a number “n” ] 3n
[ plus 4 ] + 4
[ equals 27 ] = 27
[ all together ] <u>3n + 4 = 27</u>
<u />
<u>Solving:</u>
[ given ] 3n + 4 = 27
[ subtract 4 from both sides ] 3n = 23
[ divide both sides by 3 ] n = 7
2:Seventeen equals seven less than three times a number “n” what would the expression look like?
[ Seventeen equals ] 17 =
[ seven less than ] - 7
[ three times a number “n” ] 3n
[ all together ] <u>17 = 3n - 7</u>
<u />
<u>Solving:</u>
[ given ] 17 = 3n - 7
[ add 7 to both sides ] 24 = 3n
[ divide both sides by 3 ] 8 = n
Have a nice day!

Answer:
7q-35
Step-by-step explanation:
Answer:
The correct option is y ≤1/3 x – 4
Step-by-step explanation:
If you look at the attached graph you will see that the inequality is the shaded area below the solid line.
The slope of the line is positive which is 1/3.
The y intercept is equal to -4
Thus the inequality must be:
y ≤1/3 x – 4
Therefore the correct option is:
y ≤1/3 x – 4 ....
Let's simplify step-by-step.
−6x−4y+x−2y
=−6x+−4y+x+−2y
Combine Like Terms:
=−6x+−4y+x+−2y
=(−6x+x)+(−4y+−2y)
= −5x+−6y
