6>4-2x<4
so therefor (4x-2) must be less than 6 and less than 4
it must be
6>4-2x and 4<4-2x
find the intersection
6>4-2x
add 2x to both sides
6+2x>4
subtract 6
2x>-2
divide by 2
x>-1
4>4-2x
add 2x
4+2x>4
subtract 4
2x>0
x>0
so we have
x>0
and x>-1
the range of x>-1 includes most of x>0 so the answer is
x>-1
Alex = 6x
Peter = x
6x = x + 50
5x = 50
x = 10
Alex = £60
Peter = £10
together = £70
66,190 is the Answer if you add 80 to 110 and then add 190 to 66000
Answer:
Step-by-step explanation:
x = 3y.......(1)
x - 3y = 0 ....(2)
Substituting x in (1) into (2)
3y - 3y = 0

Answer:
Radius = 9
Step-by-step explanation:
Circumference = 2πr
2πr = 18 ×3.14
2πr = 56.5
6.28r = 56.5
r = 56.5/6.28
r = 9.04 round off , 9
