Find the unit rate
do 2597÷21
Answer: 124 strikeouts per year
I think it will be d because i think that’s a good guess
<span>Hello,
For this 12x-3x+11>4x-(17-9x)let's rewrite it as:
12x-3x+11>4x-17+9x
Now combine like terms:
9x+11>13x-17
Subtract 9x and add 17 to get:
28>4x
Divide by 4:
7>x or rewritten as:
x<7
Make sense?</span>

Let x represent length of the stringer of the staircase.
We have been given that a builder makes staircases where each step is 29 cm long and rises 18 cm so people don't trip. Every staircase has a stringer - a diagonal support connecting all the steps. We are asked to find the length of the stringer of the staircase.
The length of the stringer of the staircase will be equal to diagonal of right triangle with two legs 29 cm and 18 cm.
Using Pythagoras theorem, we will get:



Now we will take square root of both sides of equation.



Since length cannot be negative, therefore, the length of the stringer of the staircase would be approximately 34.13 cm.
