3/4w+8=w-7, add 7 to both sides 3/4w+15=w,subtract 3/4w from each side and you get 15=1/4w 3.75=w
If n = –2, then m is equal to 13;
If n = 0, then m is equal to 7;
If n = 1, then m is equal to 4
Answer:
220 I'm pretty sure because 6×5 is 30 times 2 is 60. Then do 6×10 equals 60. Then do 5 times 10 times 2 to get 100. Then you add it all up to get 220

Step-by-step explanation:
1. 8/9 ÷ 4/9 is done by inverting the divisor (4/9) and then multiplying:
(8/9)(9/4) = 8/4 = 2 (answer)
2. 1/3 ÷ 6 is done similarly: (1/3)(1/6) = 1/18 (answer)
3. 4 ÷ 1/5 = 4 * 5 = 20 (answer)
4. 7 1/2 ÷ 1/4 = (15/2)(4/1) = 30 (answer)
