Two is equivalent to twenty and 84
Answer:
w = -1
Step-by-step explanation:
- w-5-4= -8-6w+8w ⇒ simplify
- w - 9 = - 8 + 2w ⇒ add 9 - 2w to both sides
- w - 2w = - 8 + 9 ⇒ simplify
- -w = 1 ⇒ multiply both sides by -1
- w = -1 ⇒ answer
Mary has 48 stickers. The ratio is 4:7
divide 48 with 4
48/4 = 12
Multiply 12 with 7
12 x 7 = 84
Mary buys another 8 stickers: 48 + 8 = 56
56:84 is the new ratio
hope this helps
