Answer:
x = 1
y = 30°
Step-by-step explanation:
is RS is ⊥ to TU then TS = US so we can use this equation to find 'x':
20x-3 = 5x+12
15x = 15
x = 1
we also know that RS intersecting with TU creates a 90° angle
if 3y = 90 then y = 30
6 batteries cost $7.50 because u divide 10 by 8 and then multiply by 6
you would do PEMDAS
you do -3 times 4. then you do that and devide by -3.
