Find Z for the following proportion

2 answers:

This is the simplest proportion i have seen.
This is how we do it:
$\frac{z}{7}$ = $\frac{1}{7}$
The answer surprisingly is obvious, z = 1
But we can still do cross multiplication

7z = 7
Divide by 7 to isolate z

$\frac{7z}{7} = \frac{7}{7}$
7 and 7 cancels out
z = 1

A red token is worth twice as much as an orange token. An orange token is worth 5 less a yellow token. A yellow token is worth 1

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Let r represent red token,

Let o represent orange token,

Let y represent yellow token

Let g represent green token,

A red token is worth twice as much as an orange token. It means that

r = 2o

An orange token is worth 5 less a yellow token. It means that

o = y - 5

A yellow token is worth 15 less than a green token. It means that

y = g - 15

A green token is worth half as much as a blue token. It means that

g = b/2

a blue token is worth B. Therefore, the worth of a yellow token in terms of B would be

Substituting g = B/2 into y = g - 5, it becomes

y = B/2 - 15

Jonathon and Raymond earn a base salary plus commission. Jonathon earns $1500 plus 10% of his sales each month. Raymond earns $1

joja [24]

Answer:

The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

Step-by-step explanation:

Given data

Let no. of sales = x

Jonathon earning = $ 1500 + $\frac{10}{100} x$

Raymond earning = $ 1200 + $\frac{15}{100} x$

Given that the earnings of Jonathon & Raymond are same.

1500 + $\frac{10}{100} x$ = 1200 + $\frac{15}{100} x$

300 = $\frac{5}{100} x$

x = 6000 sales

Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
