St boniface Hospital raises funds for research through its annual dinner and Gala event.For this event 353 tickets are available
nignag [31]

Given:

Total number of tickets = 353

Single ticket = $92

Family ticket = $122

Total sales = $39946

To find:

The number of family tickets.

Solution:

Let x be the number of single tickets and y be the number of family tickets.

Total tickets: x+y=353         ...(i)

Total sales: 92x+122y=39946          ...(ii)

Multiply (i) by 92 and subtract the result from (ii).

92x+122y-92(x+y)=39946-92(353)

92x+122y-92x-92y=39946-32476

30y=7470

Divide both sides by 30.

y=\dfrac{7470}{30}

y=249

Therefore, the number of family tickets is 249.

In the equation 3/4y+1/2=3 1/4, the fractional coefficient is what
AURORKA [14]

Answer:

\frac{3}{4}

Step-by-step explanation:

Given equation: \frac{3}{4}y + \frac{1}{2} = 3 \frac{1}{4}

In the given equation, \frac{3}{4} is a coefficient and y is the variable.

coefficient is a constant number or quantity multiplied to a variable in an algebric expression. Like in the above equation \frac{3}{4} is a coefficient and y is the variable. We use term variable for y as its value may vary or change. If variable does not have any coefficient in any expression then in that case, we consider 1 as coefficient, for example: x+4, here variable have 1 as coefficient.

Hence, the fractional coefficient is \frac{3}{4}.

◆ Quadratic Equations ◆<br>Please help !
Mila [183]
I'm sure there's an easier way of solving it than the way I did, but I'm not sure what it could be. Never dealt with a problem like this before.

Anyway, I just plugged in and tested. Chose random values for a, b, c, and d, which follow the rule 0 < a < b < c < d:

a = 1
b = 2
c = 3
d = 4

\sf ax^2+(1-a(b+c))x+abc-d)

\sf 1x^2+(1-1(2+3))x+(1)(2)(3)-(4))

Simplify into standard form:

\sf x^2+(1-1(5))x+6-4

\sf x^2+(1-5)x+2

\sf x^2-4x+2

Use the quadratic formula to solve:

\sf x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

For functions in the form of \sf ax^2+bx+c. So in this case:

a = 1
b = -4
c = 2

Plug them in:

\sf x=\dfrac{4\pm\sqrt{(-4)^2-4(1)(2)}}{2(1)}

Solve for 'x':

\sf x=\dfrac{4\pm\sqrt{16-8}}{2}

\sf x=\dfrac{4\pm\sqrt{8}}{2}

\sf x\approx\dfrac{4\pm 2.83}{2}

\sf x\approx 0.59,3.41

So the answer would be A.
