Sorry I just saw this but the answer would be (please give brainliest)
A: Be sure the formula is in the form t=d/v because we want to find the value of t. Additional info needed: d = distance from Sun to Earth (an average value because orbit of Earth is not a perfect circle) v = velocity (or speed) of light And, if we want the answer in minutes, we may need to convert seconds to minutes. The value of v (meters/sec) and d (meters) should be compatible, or we have to convert them also.
B: d=vt d/v = t [divide both sides by v]
C:d = 93,000,000 miles (rounded)
v = 671,000,000 miles/hr (the speed of light, rounded)
D:t = d/v = 93000000/671000000 = 0.14 hours (rounded) This is (0.14)*60 = 8.4 minutes or <span>8 minutes 24 seconds
</span>
E: 128100/5280=24.621 miles
t=24.261/335.92
t=0.07222 hours
t=0.07222 times 3600
t=260 seconds
Hi!
Let's write the equation in number form first.
7 over 8
7/8
minus 1
7/8 - 1
over x
7/8 - 1/x
equals 3
7/8 - 1/x = 3
over 4
7/8 - 1/x = 3/4
Now to find the value, let's put each option as the value for x.
A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.
B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.
C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.
D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!
The answer is d. x = 8
Hope this helps! :)

It’s 25 bc every 2 it goes up 5 dollars
Answer:
13/20
Step-by-step explanation:
2/5 and 1/4 common denominator is 20, so 2/5 -> 8/20 and 1/4 -> 5/20, 5/20+8/20=13/20
