15x + 2 = 45x + 4
Subtract 2 from both sides, as well as subtracting 45x from both sides.
15x - 45x = 4 - 2
-30x = 2
Divide both sides by -30.
x = 2/-30
x = - 1/15

Answer:
Scale factor for the drawing from actual park = 
Area of the actual park = 1200 cm²
Step-by-step explanation:
Length of the rectangular city park = 5 cm
Width of the rectangular park = 6 cm
Using scale factor 1 cm = 20 meters
Scale factor = 

Actual length = 5 × 20 = 100 meters
Actual width = 6 × 20 = 120 meters
Area of the rectangular park = length × width
= 100 × 120
= 1200 square meters
Therefore, Scale factor from actual length to the length in drawing = 1 : 20
Area of the rectangular park = 1200 square feet

Step-by-step explanation:
P=2L+2W
P-2W=2L
P/2-W=L
L=P/2-W
Answer:
Let the number be n.
3n - 4= -15
3n= -15+4
3n= -11
n= -11/3
n= -3.67 or n= -3 2/3
Step-by-step explanation:
Bring over 4 to the RHS of the equation and divide the RHS by 3.
