Kylie and her sister each have 1/4 cup of chopped pineapple.how much pineapple do they have in all

Levart [38]

$\text {Kylie =} \dfrac{1}{4} \text { cup}$

$\text {Sister =} \dfrac{1}{4} \text { cup}$

To find how much do they have in all, we add them:

$\dfrac{1}{4} + \dfrac{1}{4} = \dfrac{2}{4}$

Then we try to reduce the fraction to the simplest possible:

$\dfrac{2}{4} = \dfrac{2\div 2}{4 \div 2} = \dfrac{1}{2}$

$\text {Answer= } \dfrac{1}{2}$

Make a the subject of this formula:<br> p=n^2+a/n+a

GalinKa [24]

Step-by-step explanation:

we multiply both sides by the denominator on the right to eliminate fraction, so we have..

p*(n+a)= (n²+a/n+a)*n+a

so we have

p(n+a)= n²+a

so opening the bracket on the left hand side we have,

p*n+p*a

pn+pa

so,

pn+pa= n²+a

so collecting like terms we have,

pn-n²= a-pa

so removing a from the equation on the right hand side we have,

pn-n²=a(1-p)

dividing both sides by the equation in the bracket on the right hand side, we have..

pn-n²/(1-p)= a

a = pn-n²/1-p

a = n(p-n)/1-p
