There is not a formula for everything need more data
Since 5 miles is equaled to 4 inches multiply the 8 miles by 4/5 to get 6 2/5
Answer:
x= 0.5
or x= -1.5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x2+4x−3=0
Step 1: Factor left side of equation.
(2x−1)(2x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or 2x+3=0
x= 1/2 or x= −3/2
465 -(-45) = x
This creates a double negative which becomes a positive and you solution would be 465+45 =X, X = 510
