Answer:
from this table we can tell Y is always 10 times bigger then X so we just have to multiply it again by ten so the answers are
300
500
700
N + d = 21
0.5n + 0.10d = 1.35
5n + 10d = 135
d = 21-n
5n + 210 - 10n = 135
-5n = -75
n = 15
d = 6
Answer:
Siti's money = RM 430
David = RM 1,290
Farid = RM 280
Step-by-step explanation:
Let
Siti's money = x
David = 3x
Farid = x - 150
Total of their money = RM 2 000
x + 3x + (x - 150) = 2000
4x + x - 150 = 2000
5x = 2000 + 150
5x = 2,150
x = 2,150/5
x = RM 430
Siti's money = x
= RM 430
David = 3x
= 3(430)
= RM 1,290
Farid = x - 150
= 430 - 150
= RM 280
Here are your points (-9,-8), (-6,-2), (-2,-6)
Answer:
a. 440
b. 100
c. 1800
d. 320
Step-by-step explanation:
a. $7000 is 3000 +4000 so this falls in two pay ranges.
0.04(3000) + 0.08(4000) = 120+320 = $440
b. $2500 is lower than 300 so it falls in only one pay range.
0.04(2500) = $100
c. 12,000 is greater than both 3000 and 8000 so this falls in the last pay range.
0.15(12000) = $1800
d. $5500 is 3000+2500 so this falls in two pay ranges.
0.04(3000) + 0.08(2500) = 120+200 = $320
