Answer: x= 18
Step-by-step explanation:
90+25+3x+11= 180
126+3x=180
3x= 54
x= 18
3(18)+11
65
The discount would be 20% of 62.50
0.2(62.5) = 12.50 <== ur discount
Answer:
0 i hope this helps
Step-by-step explanation:
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0
.
3x−2=0
x+4=0
Set the first factor equal to 0
and solve.
Tap for more steps...
x=23
Set the next factor equal to 0
and solve.
Tap for more steps...
x=−4
The final solution is all the values that make (3x−2)(x+4)=0
true.
x=23,−4

State if the product of rational numbers and integer is an integer
The statement is false and the proof is as follows
Literally, rational numbers are decimal numbers that can be represented as a fraction of two integers;
Take for instance: 0.2, 0.5, 2.25, etc.
When any of these numbers is multiplied by an integer, the resulting number can take any of two forms;
1. It can result to an integer:
<em>For instance;</em>
![0.2 * 5 = 1](https://tex.z-dn.net/?f=0.2%20%2A%205%20%3D%201)
![0.5 * 4 = 2](https://tex.z-dn.net/?f=0.5%20%2A%204%20%3D%202)
![2.25 * 8 = 18](https://tex.z-dn.net/?f=2.25%20%2A%208%20%3D%2018)
2. It can result in a decimal number
<em>For instance;</em>
![0.2 * 3 = 0.6](https://tex.z-dn.net/?f=0.2%20%2A%203%20%3D%200.6)
![0.5 * 5 = 2.5](https://tex.z-dn.net/?f=0.5%20%2A%205%20%3D%202.5)
![2.25 * 7 = 15.75](https://tex.z-dn.net/?f=2.25%20%2A%207%20%3D%2015.75)
From (1) above, we understand that the product can result in an integer.
Hence, the statement is false
