Answer:
$220
Step-by-step explanation:
Make a proportion
We know that 99 over some number (x) must equal 45%
99/x=45/100
Cross multiply
45x=9,900
Divide by 45 on both sides
x=220
So, the tablet costs $220
Hope this helps! :)
Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be 
. Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.
