He doesn't have a positive number. Add $45 and $112 together and it exceeds $79
<span>3x + 8x + 4x = 6x + 63
15x = 6x + 63
9x = 63
x = 7
so
5x+ 23 =5(7) + 23 = 35+23 = 58</span>
Answer:
4 and 6
Step-by-step explanation:
2(2x-4)+2(2x-2)=20
4x-8+4x-4=20
8x-12=20
8x=32
32/8=4
X=4
Answer:
0.8
Step-by-step explanation:
Given that:
Speed of light = 3 * 10^8 m/s
Distance of sun to Mars = 230,000,000 meters
How many seconds does it take for sunlight to reach Mars?
Using the relation :
Speed = distance / time
Hence ;
Time = Distance / Speed
Time = 2.3 * 10^8 / 3 * 10^8
Time = 0.766
Time = 0.8 ( nearest tenth)
