Answer:
1423/33
Step-by-step explanation:
Let x = 43.121212.........
Two digits are repeating after decimal point. So multiply both sides by 100
100x = 4312.1212 --------------(I)
<u> x = 43.1212 </u> -----------(II) { subtract equation (II) form (I)}
99x = 4269
x= 4269/99 {reduce to simplest form by giving by 3rd table}
x = 1423/33
Answer:
![x < 2.5](https://tex.z-dn.net/?f=x%20%3C%202.5)
Step-by-step explanation:
![- 4x + 5 > - 5 \\ - 4x > - 5 - 5 \\ - 4x > - 10 \\ \frac{ - 4x}{ - 4} > \frac{ - 10}{ - 4} \\ x < \frac{5}{2} \\ x < 2.5](https://tex.z-dn.net/?f=%20-%204x%20%2B%205%20%3E%20%20-%205%20%5C%5C%20%20-%204x%20%3E%20%20-%205%20-%205%20%5C%5C%20%20-%204x%20%3E%20%20-%2010%20%5C%5C%20%20%5Cfrac%7B%20-%204x%7D%7B%20-%204%7D%20%20%3E%20%20%5Cfrac%7B%20-%2010%7D%7B%20-%204%7D%20%20%5C%5C%20x%20%3C%20%20%5Cfrac%7B5%7D%7B2%7D%20%20%5C%5C%20x%20%3C%202.5)
hope this helps

good luck! have a nice day!
we know that
A number is an inequality solution if the number satisfies the inequality
<u>Part 1)</u> ![10.6 < b](https://tex.z-dn.net/?f=10.6%20%3C%20b)
rewrite the inequality
![b > 10.6](https://tex.z-dn.net/?f=b%20%3E%2010.6)
The answer Part 1) is the option D ![14](https://tex.z-dn.net/?f=14)
Because
satisfies the inequality
-----> is true
<u>Part 2)</u> ![m > 7/12](https://tex.z-dn.net/?f=m%20%3E%207%2F12)
The answer Part 2) is the option A ![1](https://tex.z-dn.net/?f=1)
Because
satisfies the inequality
-----> is true
<u>Part 3)</u> ![8< x(7-x)](https://tex.z-dn.net/?f=8%3C%20x%287-x%29)
we're going to verify every case
<u>case A)</u> For ![x=2](https://tex.z-dn.net/?f=x%3D2)
substitute the value of x in the inequality
![8< 2(7-2)](https://tex.z-dn.net/?f=8%3C%202%287-2%29)
------> is true
therefore
The number
is a solution
<u>case B)</u> For ![x=8](https://tex.z-dn.net/?f=x%3D8)
substitute the value of x in the inequality
![8< 8(7-8)](https://tex.z-dn.net/?f=8%3C%208%287-8%29)
------> is not true
therefore
The number
is not a solution
<u>case C)</u> For ![x=-1](https://tex.z-dn.net/?f=x%3D-1)
substitute the value of x in the inequality
![8< -1(7-(-1))](https://tex.z-dn.net/?f=8%3C%20-1%287-%28-1%29%29)
------> is not true
therefore
The number
is not a solution
<u>case D)</u> For ![x=0](https://tex.z-dn.net/?f=x%3D0)
substitute the value of x in the inequality
![8< 0(7-0)](https://tex.z-dn.net/?f=8%3C%200%287-0%29)
------> is not true
therefore
The number
is not a solution
therefore
The answer Part 3) is the option A ![2](https://tex.z-dn.net/?f=2)
Answer:
Addition
Step-by-step explanation:
1) Add 275 to both sides.
![800 + 275 = p](https://tex.z-dn.net/?f=800%20%2B%20275%20%3D%20p)
2) Simplify 800 + 275 to 1075.
![1075 = p](https://tex.z-dn.net/?f=1075%20%3D%20p)
3) Switch sides.
![p = 1075](https://tex.z-dn.net/?f=p%20%3D%201075)
We need to add in order to solve the equation.
so therefor, the answer is option G.
3 men - 4 days |divide 3
1 man - 4/3 day |multiply 2
2 men - 8/3 day
Two men would build this fence in 8/3 day.
