Blue and green dye are mixed in a 7 : 4 ratio to make 44 litres of a teal- coloured dye. A further 8 litres of green dye are added to the mixture. What
is the new ratio of blue to green dye in its simplest form?

7:6

Step-by-step explanation:

7+4 = 11. 44/11 = 4. That means there are 7*4 = 28 blue dye and 4*4 = 16green dye. 16 + 8 =24. Blue dye to green dye would then be 28/24 = 14/12 = 7/6, so the ratio is 7:6

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
