The first step would be applying the distributive property.

2x - 1(5 - 3x) = 4x + 2

Distributive property.

2x - 5 + 3x = 4x + 2 is what the equation looks like after successfully applying the distributive property.

Dave can run the 440 yard dash in 55 seconds, and Jack can run it in 88 seconds. How great a handicap must Dave give Jack for th

Viefleur [7K]

For this case we have to, so that both runners finish at the same time, Dave must also reach 88 seconds.

$Dave\ runs\ to\ \frac {440} {55} = 8\ yards\ per\ second\\Jack\ runs\ to\ \frac {440} {88} = 5\ yards\ per\ second$

With respect to the times we have:

$88-55 = 33$

Dave must have a 33-second disadvantage.

This means that in those 33 seconds of difference Jack runs:

$5 * 33 = 165 \ yards$

So, Dave must lose 165 yards to get to Jack

Answer:

165
