About how many inches are equalvilant to 3 meters? round the numbers to the nearest tenth

118.1 meter

Step-by-step explanation:

by definition,

1 meter = 39.37 inches

hence,

3 meters = 39.37 x 3 = 118.11 = 118.1 meters (nearest tenth)

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
