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

3x+4y=2 4x-4y=12 elimination

Advocard [28]

3x+4y=2
+ 4x-4y=12 add them since 4y and -4y can cancel out
7x=14 divide each side by 7
x=2

3x+4y=2 x=2
3(2)+4y=2 substitute
6+4y=2
-6 -6
4y=-4 divide each side by 4
y=-1

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:

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

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