Answer:
Y= 1/-2
Step-by-step explanation:
10(1-2y)=5(2y-1)
10-20y= -10y+5
10+5= -20y-10y
15= -30y
y= 15/-30 or 1/-2
Answer:
Sam
Step-by-step explanation:
Just put them into a fraction for Sam its 15/5 and the ratio (basically a fraction) is 3/1 so if you simplify the 15/5, you’d get 3/1 which is the same so sam’s ratio is corrrect
The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5
