The shortest route from Cardiff to London is 120 miles. A lorry is going to take 2 hours travelling using this route.
The lorry actually travels by a different route and this is increased by 20% but still in 2 hours. By how many more MPH than the expected speed does the lorry travel.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
