Answer:
y= 20
Step-by-step explanation:
y=2*5x
Let x =2
y = 2*5 (2)
y = 10*2
y= 20
1/2 b-39=101
+39 +39
1/2 b= 140
2(1/2) b= 140(2)
b=280
Its true because integers are negative and positive numbers including zero, and a whole number is a positive counting number including zero
The only two numbers can be a factor of 5 in the ones place is 5 and 1
