If x:y=11:8 and z:y=6:7<br><br>(i) Calculate x:y:z<br><br>(ii) x:z​
kozerog [31]

Answer:

77:56:48

77:48

Step-by-step explanation:

If x:y=11:8 and z:y=6:7

then;

x/y = 11/8 and z/y = 6/7

11y = 8x and 6y = 7z

x = 11y/8 anad z = 6y/7

Hence;

x:y:z

= 11y/8:y:6y/7

= 11/8:1:6/7

= 11/8 * 7/6

= 77:56:48

x:z = 11y/8:6y/7

x:z = 11/8:6/7

x:z = 77:48

      x=2 

3x+4y=2   x=2
3(2)+4y=2        substitute

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}
