< 2 + < 3 + 90 = 180
< 2 = x + 8
< 3 = 2x + 7
x + 8 + 2x + 7 + 90 = 180
3x + 105 = 180
3x = 180 - 105
3x = 75
x = 75/3
x = 25
< 2 = x + 8 = 25 + 8 = 33 <==== answer is D
< 3 = 2x + 7 = 2(25) + 7 = 50 + 7 = 57
It is a: -1/3. You multiply -1/4 and 1 1/3 and get -1/3/
Answer:
There are 10 packets of sweet-pepper seeds and 6 packets of hot-pepper seeds.
Step-by-step explanation:
Let h represent the number of packets of hot pepper seeds. Then 16-h is the number of packets of sweet pepper seeds. The total cost of a 16-packet mix is ...
4.56h + 2.32(16 -h) = 3.16·16
2.24h + 37.12 = 50.56 . . . . . . . simplify
2.24h = 13.44 . . . . . . . . . . . . . . subtract 37.12
13.44/2.24 = h = 6 . . . . . . . . . . divide by 2.24
16 -h = 16 -6 = 10 . . . . . . . . . . . number of sweet pepper seed packets
There are 10 packets of sweet-pepper seeds and 6 packets of hot-pepper seeds.
