the y axis isthe top and bottom the x is horizantal
That would be:-
x^2 + x - 72 = 0
(x + 9)(x - 8) = 0
smallest number is 8
Answer:
Country A = 85, Country B = 29, Country C = 20
Step-by-step explanation:
A+B+C=134 ----- eq(1)
B=C+9 ------------ eq(2)
A=36+B+C ------ eq(3)
By substituting eq(2) in eq(3), we get:
A=36+C+9+C
A=2C+45 ------- eq(4)
Now substituting eq(2) & eq(4) in eq(1), we get
2C+45+C+9+C=134
4C+54=134
4C=134-54
4C=80
C=20
Now putting the value of C in eq(2),
B=20+9
B=29
Substituting the value of B & C in eq(1), we get:
A+29+20=134
A+49=134
A=134-49
A=85
What are u asking ? 30 minutes of 3 hrs the fraction would be 2/6 simplified would be 1/3 and the percentage would be 33.3 repeating percent
3/5 = 51/85
Therefore, 51 red marbles and 85 green marbles follows the required ratio.
