Answer:
The answer is 36. Say 42 + 42 is 84. Since one of the number is 6 more than the other, add 6 the first 42 and subtract 6 from the other number which will be 48 + 36 = 84. So the smaller of the two is 36.

Answer:
75
Step-by-step explanation:
5(6+9)
Times the five by the numbers in the bracket
30 + 45
= 75
Find the decimal equivalent of 2 1/3
2 1/3 = 7/3 = 2.333333
(4x + 9)/ 2.333333 = 3x / 0.5 Now cross multiply
0.5 * (4x + 9) = 3x * 2.333333
2x + 4.5 = 7x Transfer 2x to the right side.
4.5 = 5x
x = 4.5/5
x = 0.9
We'd best check this one
Left hand side.
(4x + 9)/2.333333
(4*0.9 + 9)/2.333333
(3.6 + 9)/2.333333
12.6/2.333333
5.4
Right hand side
3x/0.5
= 3*0.9/0.5
= 2.7/0.5
= 5.4
And it checks.
