Share £40 in the ratio 1 : 4 between Tim and Sam.
Tim will get
£
Sam will get
£

Tim: £8

Sam: £32

8/32=1/4

Step-by-step explanation:

Let t be Tim's share, and s Sam's one.

t/s=1/4 -> s=4t

t+s=40

t+4t=40, 5t=40, t=8, s=32

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
