Y = x-4
2x + y = 5
2x + (x-4) = 5
3x - 4 = 5
3x = 9
x = 3
Step 1.
Use the compass. Place the point of the compass on Q
Draw an arc that intersects the lines of the angle. ( the arc should intersect lines PQ and RQ)
Step 2.
Locate the place where the arc intersects line PQ, put your point on the intersection, and draw another arc that is a little bit bigger than half of the angle. Do the same for line RQ. (the result should be that the two arcs you just drew form a curved x. The arc that you drew in step 1 also should be running through the middle of your x)
Step 3.
You now should have a total of three arcs. Find the point where all three arcs intersect, and draw a line from the point to point Q
22. 14x
24. 14y+4x
26.8x
28. 7(5x+9y)
30. 7x+(3 x 4) [not sure]
32. 4y & 3y are like terms
5 is a constant
Answer:
No, it's not.
Step-by-step explanation:
2b + y = 15 is not an expression because it's an equation containing an equal sign. An expression cannot include inequality signs or equal signs.
Unlike bony fish, sharks do not have gas-filled swim bladders for buoyancy. Instead, sharks rely on a large liver filled with oil that contains squalene, and their cartilage, which is about half the normal density of bone.
