D varies jointly as h and g. if d=15 when h= 14 and g=5, find g when h=21 and d=8

g = 1.78

Step-by-step explanation:

Given that,

d varies jointly as h and g.

.....(1)

Where

k is constant of proportionality.

Put d=15, h= 14 and g=5 in equation (1) to find k.

Now, put k = 3/14, h = 21 and d = 8 in equation (1) to find g.

So, the required value of g is 1.78.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
