Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
the answer is z=3. hope this helps
Answer:
Step-by-step explanation:
arc ST is 122° , it's the same as that inner angle
arc RT ( not asked for, but needed ) is 180 °
then arc RS is 360 -180-122= RS
58= RS
Then SRT is a racing version of cars from Chrysler / Dodge :0 or also for this problem it's 180+58 =238°
