Answer:
5) 35
6) 24
7) 28
8) 67
9) 20
10) 11
11) 7
12) 21
Step-by-step explanation:
Looks like you get most of the rules involved so I'll just write the steps
5) x+4x+5 = 180
5x + 5 = 180
5x = 175
x = 35
6) 6x = 144
x = 24
7) x+27 = 2x-1
27 = x-1
28 = x
8) 63+2x-17 = 180
2x + 46 = 180
2x = 134
x = 67
9) 9x-28 = 7x +12
2x = 40
x = 20
10) 5x+7 = 62
5x=55
x=11
11) 41=7x-8]49=7x
7=x
12) 114=6x-12
126=6x
21 = x
If you wanna check it just plug in the values
That's about it
S = Speed
D = Distance
T = Time
S = D/T
S = 50m/1/2
50 divided by 1/2 = 25
25 = 50/1/2
S = 25 m/min.
