It's between 101 and 199.
5 less than 10 is 5.
2 more than 5 is 7
My guess is 157
20× 8 = 160
160 + 2x > or = 500
-160--------------- -160
2x > or = 340
÷2------------÷2
x > or = 170

Answer:
x = 10
y = 25
Step-by-step explanation:
if you add the equations as they are then the 'y-term' is eliminated:
60x = 600
x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100
200 - 100 = 100
100 = 100
Result:
5
/5 : 1
/2 = 5
/5 · 2
/1 = 5 · 2
/5 · 1 = 10
/5 = 2
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
