Answer:
w=7
Step-by-step explanation:
3w+4w=49
7w=49
w=49/7
w=7
All we have to do is divide the distance of the old sidewalk by 3.14:
65 / 3.14 ≈ 20.7006
That means that, rounded to the nearest meter, the new sidewalk is:
21 meters long!
For the first question, it would be D:

÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by

or 0.25. For the third question, it would be D.

. This can be solved by dividing

by 3. For the fourth question, the answer would be

. This can be found by flipping the 4, which would make it look like

, and multiplying it by

. For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.
