N(6) - 17 is an algebraic expression. Here are some examples of them : 9 + x, 14 - p, and 7 ÷ 2n. A numerical expression is just numbers like 8+9-10 or 7^3+9. Hope I helped!

Dwayne hikes 60 miles in 3 days. At that rate, how many days does it take him to hike a total of 240 miles

NNADVOKAT [17]

12 days. 60 is a quarter of 240. So, multiply 60 by 4 to get 240.

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual

zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle $A=a\cdot b$ assuming $a=600km, \ b=450km$ and get $A=600\cdot 450=270000km^2$ which is an actual area of Colorado
