For what value of x is the given parallelogram a rhombus ?

Solution:

We know that:

This means that:

Step-by step calculations:

Open the parenthesis:

Subtract 7x both sides:

Add 8 both sides:

Divide 2 both sides:

the answer will be

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
