<span>x – y = 30, when y = 15
x - 15 = 30
x = 30 + 15
x = 45
answer: </span><span>when y = 15, x = 45</span>
1/8; 0.2; 13/26; 3/5; 7/8; 1.09; 1.19; 1.5; 1.9
1) y = x
2) y = -(1/5)x + 4
3) y = -6x + 2
4) y = x + 2
5) y = (1/2)x + 2
6) y = -x + 4
7) y = -x + 1
8) y = (3/2)x + 2
9) y = -(3/2)x - 2
10) y = 2x - 1
Take bus=5 times walk
b=5w
b+w=24
sub 5w for b
5w+w=24
6w=24
divide both sides by 6
w=4
sub back
b=5w
b=5(4)
b=20
bus-walk=20-4=16
answer is 16 more take the bus than walk
