What is the solution to this system of equations?
3x + y = 17
x + 2y = 49

A. It has no solution.
B. It has infinite solutions.
C. It has a single solution: x = 15, y = 17.
D. It has a single solution: x = -3, y = 26.

D...i think

Step-by-step explanation:

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
