Lets say, I bought 3 cakes in the store and I spent $300, how much does a cake cost?
The equation representing that situation is the following, calling x the cake cost, our unknown factor:
3x = 300
we can solve this equation by dividing all equation by 3:
x = 100
therefore each cake costs $100

I want to buy eight bracelets, I don't know how much each bracelet costs, but the final cost will be $39.67.
The equation would look like this:
8 x <em>c</em> = 39.67
Where <em>c</em> equals cost.
To find the answer I would do the following:
8 x <em>c </em>= 39.67
<em>c</em> = 39.67 / 8
<em>c</em> ≈ 4.95
Each bracelet costs about $4.95.

Y Varies directly as X and inversely as Z. Y=100 when X=5 and Z=10 Find Y when X=3 and Z=60
Law Incorporation [45]

Answer:

y = 10

Step-by-step explanation:

based on the question if y  varries directly as x

mathematically

y ∝ x

also, y varries inversly as z can be mathematically expressed as

y ∝ 1/z

combining the two expressions

y ∝ x ∝ 1/z

i. e

y = kx/z..... where k is the constant of proportionality

make  k the subject of formulae

yz = kx

Divide both sides by x

k =yz/x

when y=100 , x = 5 z =10

k = 100 × 10/5

k = 200

to find y when x = 3 and z = 60

<h3>from the equation connecting x,y,z</h3>

k =yz/x

200 =60y/3

cross multiply

60y = 200 × 3

60y = 600

divide both sides by 60

y = 10
