In order to multiply or divide a fraction by a mixed numeral, it is best to have them BOTH in fraction form. 1) We'll convert 1 2/5 into an improper fraction. (1×5)+2 = 7/5
Now 6/7 ÷ 7/5
2) when dividing by a fraction, it is the same to multiply by its reciprocal. So flip the second fraction and multiply them: 6/7 ÷ 7/5 = 6/7 × 5/7
3) reduce them: there is nothing on top that reduces with the bottom, so we simply multiply
4) multiply numerators, then multiply denominators and keep them in place: 6×5 = 30, 7×7 = 49
5) so our final answer is 30/49
The answer is B. 7 times a number plus 4 would be 7n +4.

Answer:
29) x = 17
30) x =14
31) x = 23
32) x = 44
Step-by-step explanation:
29)
6x - 17 = 85
6x = 102
x = 17
30)
4x + 21 + 103 = 180
4x + 124 = 180
4x = 56
x = 14
31)
2x + 23 = 4x - 23
-2x = - 46
x = 23
32)
4x - 42 = 134
4x = 176
x = 44
