Answer:
10/3 or 3 1/3
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
0.5(n-4)-3=3-(n+3)
First, you would do the distributive property:
0.5n-2-3=3-n-3
Then you would simplify and then solve.
0.5n-5=-n
-5=-1.5n
n=5/1.5
n=10/3 or 3 1/3

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88
Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.
<h3>How do we derive a numerical expression?</h3>
Let:
x = amount of time it takes Imani to walk to school
y = amount of time it takes Imani to ride to school = 3 minutes
The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:
x = 5y - 1
Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:
x = (5 * 3) - 1 = 15 - 1 = 14 minutes
