23n=2.4 A. 3.6 B. 7.2 C. 1.2 D. 1.6

$\huge\text{Hey there!}$

$\mathsf{23n =2.4}$

$\large\text{DIVIDE 23 to BOTH SIDES}$

$\mathsf{\dfrac{23n}{23}=\dfrac{2.4}{23}}$

$\large\text{Cancel out: }\mathsf{\dfrac{23}{23}}\large\text{ because it gives you 1}$

$\large\text{Keep: }\mathsf{\dfrac{2.4}{23}}\large\text{ because it helps us solve for n}$

$\mathsf{n = \dfrac{2.4}{23}}$

$\mathsd{\dfrac{2.4}{23}= 2.4\div 23\rightarrow \bf 0.104348}$

$\boxed{\boxed{\large\textsf{Answer: \huge n = \bf 0.104348}}}\huge\checkmark$

$\boxed{\textsf{NONE OF THE ABOVE is your ANSWER}}$

Question #19- Use the answer bank below to fill in missing parts of the proof.

serious [3.7K]

Answer:

∠MPQ ≅ ∠MPR: Reason; Corresponding parts of congruent triangles are congruent (CPCTC)

∠PQR ≅∠PRQ: Reason; CPCTC

Step-by-step explanation:

$\overline{PQ}\cong \overline{PR}$ : Reason; Given

Draw $\overline{PM}$ so that M is the midpoint of $\overline{QR}$ : Reason; Two points determine a line

$\overline{QM}\cong \overline{RM}$ : Reason; Definition of midpoint

$\overline{PM}\cong \overline{PM}$ : Reason; Reflexive property

ΔPQM ≅ ΔPRM: Reason; Side Side Side (SSS) rule for triangle congruency

∠MPQ ≅ ∠MPR: Corresponding parts of congruent triangles are congruent CPCTC

∠PQR ≅∠PRQ: CPCTC
