Step-by-step explanation:
product=× three=3 a number is unknown =x plus=+ five=5 is=equals to 20
3×x +5=20
3x+5=20
Subtract 5 from both sides
3x+5-5=20-5
3x=15
3x/3=15/3
x=5
70mi/1hr x 1hr/60min x 1min/60sec= .0194/1sec
It is A because you are adding 3 to in if you were to subtract then it will go down not up.
