We have trapezoid with congruent legs.
30x + 11y = 2x + 3
28x +11y = 3
Also we have
30x + 11y = 12
We got 2 equations:
30x + 11y = 12
28x +11y = 3 (*-1) -----> -28x -11y = -3
30x + 11y = 12
<u> -28x -11y = -3</u>
2x = 9
x=9/2
30x + 11y = 12 ------> 30*9/2 +11y =12 ------> 135+11y =12, ---> 11y = - 123,
y= - 123/11
I think its 3 - (0,10, 42)
if you put in the values of the given x, then these are the resulting y values.
Answer:
-36
Step-by-step explanation:
-48+12=-36
1 meter = 100 centimeters, so 120 centimeters equal to 1.2 meters.
