Is that all the information? it could literally be any number with only that.
Answer:
75cm
Step-by-step explanation:
Well, I can't see a photo, so I'll have to assume that the description provides enough info.
10cm/2km = x/15km,
where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.
10cm/2km = x/15km
10/2 = 5/1
This means we have to multiply 5 by 15 to find x.
x = 5 · 15
x = 75
Let's plug the new value back in...
10cm/2km = x/15km
10cm/2km = (75cm)/15km
<em>(Simplify each side to its simplest form)</em>
10cm/2km = 75cm/15km
5/1 = 5/1
It works! So x = 75cm.
Hope this helps! :)
2x+9=6x+7. 2x+2=6x. 2=4x. X=1/2 a year
Should be D. (5^2)^2= 5^4 (you multiply them) and 5^4+5^4=5^8
Your answer is D. This is because a number multiplied by itself is x².
