Answer:
12
Step-by-step explanation:
12x -1 = 143
+1 +1 (add one to each side)
12x = 144 (That would cancel out the -1)
12x/12= x (divide each side by 12, it would leave 12x as just 12)
144/12= 12
X=12

Answer:
16 miles
Step-by-step explanation:
If 1.5 inches is equal to 4 miles, it would also mean that 3 inches is equivalent to 8 miles, since 4*2=8 and 1.5*2=3. Since we need to find it for 6 inches, we just double the number again to get 6 inches = 16 miles. (3*2=6; 8*2=16)
Answer:
x=1.6
Step-by-step explanation:
Multiply each number by 4 to make wholes and than just cross multiply.
The value of x given the perimeter of the square is 6.
<h3>What is the value of x?</h3>
The first step is to determine the perimeter of the square.
Perimeter of the square = 4 x length
4 x 2.5x = 10x yards
The perimeter of the triangle is equal to the sum of the three side lengths
2x + 4x - 2 + 2x + 14 = 10x
Combine similar terms
14 - 2 = 10x - 2x - 4x - 2x
Add similar terms
12 = 2x
Divide both sies by 2
x = 6
