I need help with proofs​

the answer is b

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
