n>- 19/33
1 Simplify 10n+4-n10n+4−n to 9n+49n+4.
1+4(-6n-4)<9n+41+4(−6n−4)<9n+4
2 Expand.
1-24n-16<9n+41−24n−16<9n+4
3 Simplify 1-24n-161−24n−16 to -24n-15−24n−15.
-24n-15<9n+4−24n−15<9n+4
4 Add 24n24n to both sides.
-15<9n+4+24n−15<9n+4+24n
5 Simplify 9n+4+24n9n+4+24n to 33n+433n+4.
-15<33n+4−15<33n+4
6 Subtract 44 from both sides.
-15-4<33n−15−4<33n
7 Simplify -15-4−15−4 to -19−19.
-19<33n−19<33n
8 Divide both sides by 3333.
-\frac{19}{33}<n−

Done
Y=x^2-4x+8 and 4x+y=12 so y=12-4x, insert y in the quadratic to get
12-4x=x^2-4x+8
12=x^2+8
0=x^2-4=(x-2)(x+2)
So the solutions are x=2 and x=-2.
Answer:
A= 29
B=34
C=117
Step-by-step explanation:
<u>A triangle has three sides and a triangle always adds up to be 180</u>
A + B + C = 180
B = A + 5
C = 4A + 1
Plug in.
A + A + 5 + 4A + 1 = 180
6A + 6 = 180
6A = 174
A = 29
<u>Now since you found A, find the other two by plugging A in!</u>
C = 4(29) + 1
C = 117
<u>Plug in the B equation</u>
B = 29 + 5
B=34
Check your answers
29 + 117 + 34 = 180
(7/8) of an hour is 52.5 minutes.
If you are looking for half of that, it would be 26.25 minutes or 26 minutes and 15 seconds.
