Answer:

The completed proof is presented as follows;

The two column proof is presented as follows;

Statements ${}$ Reason

1. $\overline {HI}$ ║ $\overline {KL}$ , J is the midpoint of $\overline {HL}$ ${}$ 1. Given

2. ∠IHJ ≅ ∠JLK ${}$ 2. Alternate angles are congruent

3. ∠IJH ≅ ∠KJL ${}$ 3. Vertically opposite angles

4. $\overline {HJ}$ ≅ $\overline {JL}$ ${}$ 4. Definition of midpoint

5. ΔHIJ ≅ ΔLKJ ${}$ 5. By ASA rule of congruency

Step-by-step explanation:

Alternate angles formed by the crossing of the two parallel lines $\overline {HI}$ and $\overline {KL}$ , by the transversal $\overline {HL}$ are equal

Vertically opposite angles formed by the crossing of two straight lines $\overline {IK}$ and $\overline {HL}$ are always equal

A midpoint divides a line into two equal halves

Angle-Side-Angle, ASA rule of congruency states that two triangles ΔHIJ and ΔLKJ, that have two congruent angles, ∠IHJ in ΔHIJ ≅ ∠JLK ${}$ in ΔLKJ and ∠IJH in ΔHIJ ≅ ∠KJL in ΔLKJ, and that the included sides between the two congruent angles is also congruent $\overline {HJ}$ ≅ $\overline {JL}$ , then the two triangles are congruent, ΔHIJ ≅ ΔLKJ.

Karrine hit 4 more home runs than half the number of home runs Lu hit. Together they hit 10 home runs. Let x represent the numbe

Andreas93 [3]

Answer:

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

Step-by-step explanation:

Let

x ----> represent the number of home runs Lu hit

y ---> represent the number of home runs Karrine hit

we know that

Together they hit 10 home runs
