Step-by-step explanation:
Don't you need a key for what K equals to solve this?
Answer:
3/8 and 1/5
Step-by-step explanation:
If the scale factor is 1 then it stays the same. If it's larger than 1 then is gets larger, so the fractions, which are smaller than 1, would make it shorter.
hope this helped :)
Lets call the number 'n'
plus means addition
is means the equal sign
so that as an expression would be
n+4=7
I would say d maybe , im not sure
Let x be the number of minutes for
his normal walk
On the way to the airport, for the
2/5 (or 40%) of his route, his speed is twice faster. Hence, the number of x
should be divided to 2. The rest of the route (60%) was on his normal pace. The
total minutes is 6. The equation is:
0.4(x÷2) + 0.6x = 6
<span>Solving for x, the number of
minutes for his normal walk is 7.5 minutes.</span>
