unit test unit test review active roses 16 acres carnations 12 acres what value correctly fills in the blank in the equation 16 + 12 = 4×(_ + 3) to flowers? 2 3 4 8

Explanation:

Step1: Simplify left - hand side

$16 + 12=28$

Step2: Rewrite the right - hand side

Let the blank be $x$. The right - hand side is $4\times(x + 3)=4x+12$.

Step3: Solve for $x$

Set up the equation $4x + 12=28$. Subtract 12 from both sides: $4x=28 - 12$, so $4x=16$. Divide both sides by 4: $x = 4$.

Answer:

4
