The ratio of money in terry's bank account to faye's bank account was 3: 5. terry then put £220 in his account and faye withdrew £300 from her account. they now had the same amount in their accounts. how much did they initially have altogether?

Terry's after amount = 3x + 220

Faye's after amount = 5x - 300

3x + 220 = 5x - 300

-2x = -80

x = 40

altogether initially = 3(40) + 5(40)

= £320.

step-by-step explanation:

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
