5200 - 700 = 4500
25 words per minute
25 × 60 = 1500 words (1 hour)
4500 ÷ 1500 = 3
Answer: 3 hours
6 m = 6 × 100 = 600 cm
3 ÷ 3 = 1
600 ÷ 3 = 200
3:600 ratio simplified is 1:200
The values of x and y are 5 and 2 respectively
Second graph
explanation:
1. they both are increasing so only graph 1 & 4 fits
2. the y-intercept of y=x+5 is 5 so it’s graph 2
