Answer:
Rewrite the equation as:
y = (231 + 7x)/25
Then plug it into a graphing calculator
Ok if there is 423 dogs and 56 big dogs need to sub the dogs and you get
423-56=357 big dogs
SO there are 357 dig dogs
732/31= 23.612 (3dp)
it’s hard to show your working out when you don’t know the 31 times table

Answer: 1.091 which is approximately 1 word per second
Step-by-step explanation:
Jack can text 180 words in 2 minutes and 45 seconds. We would convert 2 minutes to seconds
60 seconds = 1 minute
x seconds = 2 minutes
x = 2×60 = 120 seconds
2 minutes 45seconds = 120+45 = 165 seconds
This means Jack can text 180 words in 165 seconds
Let's find his unit rate in texts per second
if jack texts 180 words in 165 seconds
Then jack texts y words in 1 second
165y = 180
y = 180/165= 1.091 words per second
This is approximately 1 word per second
