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

Answer:
x<3 number line: < ---------------3 - - - - - > (open circle/parentheses on 3)
Step-by-step explanation:
first, solve for x:
2x+1<7 <-- treat the less than sign as an equal sign
2x+1=7 <-- get x by itself on the left hand side by subtracting 1 from both sides
-1 -1
2x=6 <--- divide both sides by 2 to get x by itself
2x/2 = x 6/2 = 3
x=3 < -- substitute the less than symbol back into the equation to get x<3
to plot on a number line:
x is less than 3, so on the number line, any real numbers to the left of three will be true for this equation
< ---------------3 - - - - - >
since 3 is not included in the answer, there would be an open circle or a parentheses where 3 is.
we know 3 is not included in the answer because of the inequality sign. if the inequality symbol is ≥ or ≤, then the answer on the number line would be a closed circle or a bracket.
in interval notation, the answer would be (-∞,3)
