Answer:

100 blocks.

Step-by-step explanation:

Let x represent number of blocks built by Gage.

We have been given that Colton was 5 times as fast at building the castle than Gage, so number of blocks built by Colton would be $5x$ .

We are also told that it takes 120 blocks to build the castle. Since Colton and Gage were building a castle together, so number of blocks built by both will be equal to 120.

$x+5x=120$

$6x=120$

$\frac{6x}{6}=\frac{120}{6}$

$x=20$

Number of blocks built by Colton: $5x=5\cdot 20=100$ .

Therefore, Colton had build 100 blocks.

Step-by-step explanation:

Let's simplify step-by-step.

−4(x−7)+x+14

Distribute:

=(−4)(x)+(−4)(−7)+x+14

=−4x+28+x+14

Combine Like Terms:

=−4x+28+x+14

=(−4x+x)+(28+14)
