Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.
90 = 7x + 55
35 = 7x
x = 5
Answer:
The second equation can be written by equation (1) is given below
8x-5y=3
The two equations represents the same line and therefore they have an infinite number of solutions that are true for both equations.
Step-by-step explanation:
Given equation is 
To find the second equation to create the given system of equations to have infinitely many solutions :
The second equation can be written by equation (1) is given below
8x-5y=3
The two equations represents the same line and therefore they have an infinite number of solutions that are true for both equations.
Answer:
<u>6.2% of last month's income was spent on office expenses</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Office's income last month = $ 315,600
Expenses last month = $ 19,567.20
2. What percent of last month's income was spent on office expenses?
To calculate this percent, we use this fraction:
Expenses last month/Office's income last month
Replacing with the real values:
19,567.20/315,600 = 6.2%
<u>6.2% of last month's income was spent on office expenses</u>
