1. A)
7x= 3(35)
7x= 105
105/7= 15
Therefore x=15
2. C)
0.25 inches represents 1 mile
----------------------------------------------
Find 1 inch:
----------------------------------------------
1 inch represents 1 ÷ 0.25 miles
1 inch represents 4 miles
----------------------------------------------
Find 3.75 inches:
----------------------------------------------
1 inch represents 4 miles
3.75 inches represent 4 x 3.75 miles
3.75 inches represent 15 miles
----------------------------------------------
Find 2.25 inches:
----------------------------------------------
1 inch represents 4 miles
2.25 inches represent 4 x 2.25 miles
2.25 inches represent 9 miles
----------------------------------------------
Find Area:
----------------------------------------------
Area = Length x Width
Area = 15 x 9
Area = 135 miles²
----------------------------------------------
Answer: 135 miles²
----------------------------------------------
3 3/4 divide 2 1/12 = 1.8
For this case we must find an expression equivalent to:
![\sqrt [4] {f}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7Bf%7D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So, rewriting the given expression we have:
Answer:
Option 1
