Solve for a. 1/3(21-3a)=6-a
OverLord2011 [107]

Answer:

no solution

Step-by-step explanation:

Given

\frac{1}{3} (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution

Use compatible numbers to solve the problem 488 ÷ 62.A. 450 ÷ 50 = 9B. 434 ÷ 62 = 7C. 490 ÷ 70 = 7D. 480 ÷ 60 = 8
ipn [44]

Option D is correct. The required compatible number is 480 ÷ 60 = 8

Compatible numbers are numbers that have a close approximate to a given value

Given the expression  488 ÷ 62

The compatible number for 488 is 480

The compatible number for 62 is 60

Using these compatible numbers to solve the expression will give:

488 ÷ 62

= 480 ÷ 60

= 480/60

= 48/6

= 8

Hence the correct option will be 480 ÷ 60 = 8
