Amir can seal a driveway in four hours working together he and Louis conceal it in 2.3 hours how long would it take Louis to seal it working alone

Louis can seal the driveway in 5.41 hours.

Step-by-step explanation:

+ =                  4 × 1x × 2.3 = 9.2x

9.2x(+ = )

2.3x + 9.2 = 4x

9.2 = 1.7x

x= 5.411764706

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

b if for most of the graph

d if y intercept
