Svetlana's hair is 4 cm long. her hair grows 1.5 cm per month. svetlana wants her hair to be less than 16 cm long. write an inequality to determine the number of months, m, svetlana can allow her hair to grow so that it is less than 16 cm long.

m ≤ (16 - 4) : 1.5

Step-by-step explanation:

m ≤ 8 months

God with you!!!

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
