Answer:
Step-by-step explanation:
4x + 7 + 2x + 5 = 180
6x + 12 = 180
6x = 168
x = 28
4(28) + 7= 112 + 7= 119
2(28) + 5 = 56 + 5= 61
Answer:
40 km away.
Step-by-step explanation:
a^2 + b^2 = c^2
In this case, a = 16 * 2 = 32 km, since he travels 16 km per hour for 2 hours.
b = 12 * 2 = 24 km, since she travels 12 km per hour for 2 hours.
32^2 + 24^2 = c^2
1,024 + 576 = c^2
1600 = c^2
c^2 = 1600
c = plus or minus 40
Since distance cannot be negative, they will be 40 km away.
Hope this helps!
