V*t=S
V=3x10^8 m/s
S=7.5x10^6 m
t=S/V = 7.5x10^6 / 3x10^8 = 7500 000 / 300 000 000 = 0.025 s
Answer:
x = 110
Step-by-step explanation:
You would subtract the 1 first and leave the number with the X alone. Then after you have subtracted the 1 you would want to divide the 2x by 2 and also divide the 8 by 2

Answer:
11.6
Step-by-step explanation:
<u>Solving with steps as below:</u>
- 31*r+1.1*(35−31)*r = 410.64
- 31r + 1.1*4r = 410.64
- 31r + 4.4r = 410.64
- 35.4r = 410.64
- r = 410.64/35.4
- r = 11.6
<u>Answer is:</u> r =11.6
