Answer:
300 Adults 555 Children
Step-by-step explanation:
What we know:
Firstly, at 5pm there were 36 more Children (C) than Adults (A)
So.....C = A + 36
Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855
So 4A + 5C = 855
——-
Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....
4A + 5C = 855
becomes......
4A + 5 (A + 36) = 855
Multiply the brackets (5 x A) and (5 x 36):
4A + 5A + 180 = 855
Take off 180 from both sides:
4A + 5A = 675
Therefore 9A = 675
Divide by 9:
A = 75
We know C is A + 36
C = 111
At 5 pm - A = 75 and C = 111
Therefore at 12:
There were 5 x C = 555
And 4 x A = 300
Coach Smith is buying equipment for his soccer team. He has 11 players and each player needs three uniforms, two shin guards, one ball, and two pairs of cleats.
Part A: Write an algebraic expression to represent this situation.
Part B: If each uniform costs $48.00, each shin guard costs $5.00, each ball costs $17.00, and each pair of cleats costs $89.00, determine how much Coach Smith will spend, before taxes, on equipment for his soccer team.
PART A:
Let the cost of a uniform be a, that of a shin guard, b, that of a ball, c, and that of a pair of cleats, d, then
The algebraic expression representing the situation is given by
11(3a + 2b + c + 2d)
PART B:
The amount coach smith will spend is given by
11(3(48) + 2(5) + 17 + 2(89)) = 11(144 + 10 + 17 + 178) = 11(349) = $3,839
The roots of 5x² - 4x + 3 = 0 are non-real
Step-by-step explanation:
In the quadratic equation ax² + bx + c = 0, the discriminant is
b² - 4ac, where a , b , c are constant
- If b² - 4ac ≥ 0, then the roots of the equation are real
- If b² - 4ac < 0, then the roots of the equation are non-real
∵ The quadratic equation is 5x² - 4x + 3 = 0
∵ The general form of the quadratic equation is ax² + bx + c = 0
∴ a = 5
∴ b = -4
∴ c = 3
∵ The discriminant is b² - 4ac
- Substitute the value of a , b and c in the discriminant
∴ b² - 4ac = (-4)² - 4(5)(3)
∴ b² - 4ac = 16 - 60
∴ b² - 4ac = -44
∵ -44 < 0
∴ b² - 4ac < 0
∴ The roots of the equations are non-real
The roots of 5x² - 4x + 3 = 0 are non-real
