Chase tried to solve an equation step by step. \qquad\begin{aligned} \dfrac13(g-3)& =3 \\ g-3& =9& \green{\text{step } 1} \\ g& =12& \blue{\text{step } 2} \end{aligned} 3 1 (g−3) g−3 g =3 =9 =12 step 1 step 2 find chase's mistake. choose 1 choose 1 step 1 step 2 he did not make a mistake

Aand b are correctly balanced reactions. they have the same number of atoms in both sides of the reaction

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
