10 3/5 is the correct answer
Answer:
Fred 5/8
Dan 3/8
Total =( 5/8 + 3/8 ) = 8/8
ie; the whole cake
Step-by-step explanation:
btw that was example.
Step-by-step explanation:
-4|8-5n|=19
-4/-4|8-5n|=19/-4
|8-5n|=4.75
5n=4.75-8
5n=-3.25
5n/5=-3.25/5
n=-0.65
if it is wrong sory
First convert the distance to miles
<span>9.5 × 10^12 km x 0.62 miles/km </span>
<span>= (0.62 × 9.5) x 10^12 miles </span>
<span>= 5.9 × 10^12 miles </span>
<span>But we want to triple that, because it is 3 light years (not just 1): </span>
<span>3 x 5.9 × 10^12 miles </span>
<span>≈ 18 × 10^12 miles </span>
<span>≈ 1.8 × 10^13 miles </span>
<span>Next divide by the speed to get the time (in hours). </span>
<span>t = 1.8 × 10^13 miles / 17000 miles/hour </span>
<span>Let's convert the speed to scientific notation: </span>
<span>t = 1.8 × 10^13 / 1.7 x 10^4 </span>
<span>t = (1.8 / 1.7) × (10^13 / 10^4) <-- when dividing powers with the same base, subtract the exponents </span>
<span>t ≈ 1.1 × 10^9 </span>
<span>Let's convert that back to standard notation. </span>
<span>Answer: </span>
<span>1,100,000,000 hours</span>
