Step-by-step explanation:

x=14-6y/3

substituting x=14-6y/3 into eqn 2

2(14-6y/3)+8y=2

multiplying through by 3

2(14-6y/3)×3 +8y×3=2×3

2(14-6y)+24y=6

28-12y+24y=6

28-12y=6

28-6=12y

22=12y

22/12=y

finding x

2x+8(22/12)=2

2x+44/3=2

2x=2-44/3

x=(-38/3)/2

×=-38/6

G is proportional to the square of t. If t=2 and g=64, find g when t=3.5.

choli [55]

$If\ g\ is\ proportional\ to\ the\ t^2\ we\ have\ proportion\\\\
g=64\ \ \ \ ---\ \ \ t^2=2^2=4\\\\\
g=?\ \ \ ----t^2=(3,5)^ 2=12,25\\\\
4g=64*12,25\\\\
4g=784\ \ |:4\\\\g=196\\\\ Answer\ is\ g=196\ for\ t=3,5.$

tensa zangetsu [6.8K]

Answer:

1/216

Step-by-step explanation:

I am pretty sure this is correct

you have to make the whole number 6 into a fraction 6/1

now it is 1/6 divided by 6/1 but you need to do KCF keep change flip

so now it is 1/6 times 1/6 and you get 1/36

then turn 6 into a fraction again

then KCF

Now it is 1/36 times 1/6 and you get 1/216
