Natasha2012 [34]

Given

The mass of a certain 10k gold necklace is 18 grams.

Find out how many grams of gold are in the necklace.

To proof

let us assume that the gold in the necklace be x.

As given in the question

10k gold necklace i.e gold necklace is made up of the various elements with the gold.

10k gold necklace is 18 grams.

As pure gold is of the 24k.

$x = \frac{10\times18}{24}$

solving

x =7.5 gram

7.5 grams of gold are in the necklace .

Hence proved

Solve the value of y for the given values of x: 4x = 3y - 7; x= 4,5,6

julia-pushkina [17]

Thhe easiest way would be to solve for y first
4x=3y-7
add 7
4x+7=3y
divide both sides by 3
(4x+7)/3=y

try each
x=4
(4(4)+7)/3=y
(16+7)/3=y
(23)/3=y
7 and 2/3=y
(4,7.66666)

x=5
(4(5)+7)/3=y
(20+7)/3=y
(27)/3=y
9=y
(5,9)

x=6
(4(6)+7)/3=y
(24+7)/3=y
(31)/3=y
10 and 1/3=y
(6,10.333)

(4,7.66666)
(5,9)
(6,10.333)

when x=4, y=7 and 2/3
when x=5, y=9
when x=6, y=10 and 1/3
