Class A has 25 pupils and class B has 28 pupils. Both classes sit the same maths test. The mean score for class A is 69. The mea

il63 [147K]

Answer:

Step-by-step explanation:

Mean would mean average, which in this case is $\frac{x+y}{2}$

so your equation would look like $\frac{69+x}{2}=41$

Next multiply both sides by to clear the fraction $2*(\frac{69+x}{2})$

to get $69+x=89$

Subtract 69 from both sides $69+x=82\\-69 -69$

you get $x = 13$

1 cup of flour - 4 cupcakes

18 cups of flour - x cupcakes

Write a proportion:

$\dfrac{1}{18}=\dfrac{4}{x}$

Cross multiply:

For a monic quadratic (factor of 1 on $x^2$ ) we always add half the coefficient on the linear ( $x$ ) term, so

$\left(\dfrac 7 2\right)^2 = \dfrac{49}{4}$

Answer: 49/4

$x^2 + 7x + \dfrac{49}{4} = 4 + \dfrac{49}{4}$

$(x + \frac 7 2)^2 = 4 + \frac{49}{4}$
