Answer:
y = 60, x= 50
Step-by-step explanation:
y + 120 = 180
subtract 120 from both sides
y = 60
60 + 70 = 130
x + 130 = 180
subtract 130 from both sides
x = 50
Answer:
(10x25) + (5x25)=375
Step-by-step explanation:
Ten times any number is easy because you just add a zero to the end. So mental math would say to break it into 10x25=250, plus 5x25=125, which equals 375
