Answer:
5 hours and 15 bracelets
Step-by-step explanation:
Rachel makes 3 bracelets per hour so you can set that up as the equation y=3x. Oliver can make 2 bracelets per hour but already has 5 so the equation for that is y=2x+5. These equations form a system of equations because the values for x and y are the same in both equations. This is true because the goal is to find out when Rachel and Oliver swell the same amount of bracelets. In order to solve this, you must set both of the equations equal to each other, this can be done because both equations are equal to y. The equation you now have is 3x = 2x+5. This can be solved as you would solve any linear equation; by isolating the x value then dividing it. In this case, when you do this you subtract 2x from both sides then get x=5 there is not a number multiplied by x so dividing, in this case, is not necessary. Now plug the value of x back into one of the original equations, y=15 should be the answer. Now you know that after 5 hours both Rachel and Oliver will have made 15 bracelets.
4x + 3y = 2
Both x and y have to be the same numbers!
Answer: the correct answer is 5h-3k
The true statement about an exterior angle of a triangle is C; It forms a linear pair with one of the interiior angles of the triangle .
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
We know that the exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.
The pair also rests on the same straight line and that makes a pairs.
Therefore we can say that it is formed by a linear pair with one of the interior angles of the triangle.
So, the correct answer would be C.

Answer:
D
Step-by-step explanation:
The exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.
The pair also rests on the same flat/straight line and that makes a pair.
Therefore we can say that it is formed by a linear pair/group with one of the interior/inside angles of the triangle.
So, the correct answer would be D.
Answer: the answer is y + 4 = x
