H(arold) = 2 + 2*K(enneth)

H = 2 + 2K

H + K = 38

Substitution:

2 + 2K + K = 38

3K = 36

K = 12

Kenneth solved 12 problems and Harold solved (2(12) + 2 = 24 + 2 =) 26 problems

Two angles are supplementary. Three times the measure of one angle is 20° more than the measure
In-s [12.5K]

Answer:

  50°, 130°

Step-by-step explanation:

All measures are in degrees. Let x represent "one angle". Then the other is (180-x) and we can write the relation ...

  3x = 20 +(180 -x)

  4x = 200 . . . . . . . add x, collect terms

  x = 50 . . . . . . . . . . one angle

  180 -50 = 130 . . . .the other angle

The measures of each angle are 50° and 130°.

Answer: Equation (y = 3x + 10)

Each time the number of triangles increase, the 3 also increases. For example: 2 Triangles = 3 + 3 and the 2 of the 5 remains the same no matter how many triangles there are.

Step-by-step explanation:

Let x = Number of triangles

Let y = Perimeter

Plug in formula: y = 3x + 10

y = 3 (2) + 10

y = 6 + 10

y = 16

In rectangle ABCD, if the coordinates of A are (0, 0) and of C are (r, s), find the coordinates of B and D.
goldenfox [79]

Answer:

Answers are (r,0) and (0,s)

Step-by-step explanation:

Given that in a rectangle ABCD, one vertex is the origin (0,0) A

The opposite vertex C is having coordinates as (r,s)

Since a rectangle has angle 90 we have x axis as one side and y axis as other side.

Length = r and width =s (since coordinates of C are (r,s))

Hence other coordinate B on x axis would be = (r,0)

and D on y axis = (0,s)

Answers are (r,0) and (0,s)
