Soo-Jung used the subtraction property of equality to solve an equation for y. Which equation could be the one that Soo-Jung sol
antiseptic1488 [7]

Explanation:

Option 1.

4y=12

Dividing 4 both sides

y=3

Division property should be used.

Option 2.

\dfrac{y}{4}=12

Cross multiplying each other,

y=12(4)

y=48

Option 3.

2(4y)=12

Opening bracktet in LHS

8y=12

Dividing both sides by 8 i.e.

y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}

Division property is used.

Option 4.

y+4=12

Subtracting both sides by 4 i.e.

Y+4-4=12-4

y=8

Subtraction property is used.

<em><u>It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.</u></em>

The sternal angleis the least likely part of A. the sternum to fracture in the elderly. B. occurs at the sternoclavicular joint.
Bumek [7]

Sternal angle marks the joint between the sternum and the 2nd rib.

Option E.

<h3><u>Explanation:</u></h3>

Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.

The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.

why the Eukarya domain includes more complex living things than the Archaea or Bacteria domains? A. All prokaryotes are unicellu
kykrilka [37]

Answer:

The correct answer is C eukaryotes have a greater variety of genetic material than prokaryotes.

Explanation:

Prokaryotic cells consist of single chromosome and their DNA is present in a dense region called nucleoid.As one copy of each gene is present in the chromosome prokaryotic cells are haploid.The DNA of prokaryotic cells are circular

 Whereas eukaryotic DNA is linear and multiple distinct chromosomes are present in eukaryotes.Two copies of each chromosome are present are in many eukaryotic cells.As a result the eukaryotic cells are diploid in nature.

   Due to this greater variety of genetic material the domain eukarya are more complex than archea and or bacteria domains.
