Answer:
Kim is 3, Tom is 12
Step-by-step explanation:
4x + x = 15
combine like terms
5x = 15
divide both sides by five
x = 3
7.1 is ten times smaller than 71
Step-by-step explanation:
5x-3y-4=0---------(1)
Slope = - coefficient of X/ coefficient of y
= -5/(-3)
= 5/3
(x1,y1)= (-5,7)
Equation of the line,
Y-Y1= slope(X-X1)
Y-7= (5/3)×(X-(-5))
Y-7= (5x+25)/3
3y-7=5x+25
5x-3y+32=0 is the required eqn
