Answer:
1r + 8(400) = 3(r+400)
1r + 320 = 3r + 120
2r = 200
r = 200 / 2 = 1000
1400 * 3 = 420
100 + 320 = 420

Answer:
Step-by-step explanation:
StartFraction 2 Over 5 EndFraction plus p equals StartFraction 4 Over 5 EndFraction plus StartFraction 3 Over 5 EndFraction
- 2/5 + p= 4/5 + 3/5p
- p - 3/5p = 4/5 - 2/5
- 2/5p = 2/5
- 2p = 2
- p = 1
Answer is 1
42x + 28y......the GCF is 14...so factor out 14
14(3x + 2y) <==
Look for patterns
1 to 3 is plus 2
3 to 6 is plus 3
6 to 10 is plus 4
