Answer:
y < 2X - 1
y = 2X - 1
Step-by-step explanation:
Let's try to make an equation from the worded problem.
"is Less than " means <
2 times means 2 * X
= 2X
y < 2X - 1
y = 2X - 1
Answer:
-199
Step-by-step explanation:
X - 5 <= -2
x <= 3
This is saying, x is less than or equal to 3., so take a filled dot, put it on 3, then draw a line from it towards the left
Answer:
x = 15.8114
Step-by-step explanation:
The complete question is:
"The problem is asking for value of x. Two right triangles side by side, the altitude is 9. The bottom of whole triangle is 25. One side is 15 and the other side is x. What is the value of x?"
Solution:-
- Develop a diagram for the information given " Two right triangles side by side" The altitude i.e height (common to both triangle ) = 9. The total base length of both triangles is = 25. One side is 15 and other side is x.

y D 25-y
- We will first determine the value of "y" using the left hand side triangle and apply pythagorean theorem. Where, H = 15 , P = 9 , B = y.
H^2 = P^2 + B^2
15^2 = 9^2 + y^2
y = √(225 - 81 )
y = 12
- Now we can use the value of y and apply pythagorean theorem on right hand side triangle with sides. H = x , P = 9 , B = 25-y = 25 - 12 = 13.
H^2 = P^2 + B^2
x^2 = 9^2 + 13^2
x = √( 81 + 169 )
x = 15.8114
Ince we know the answer in terms of the amount of remaining pages, we first need to calculate how much of the book<span> remains. This can be calculated as follows: 1/5 + 2/7 = (7+2*5)/35 = 17/35. Therefore, on </span>Sunday<span> the remaining pages </span>is<span> 1- 17/35 or 18/35. 5/9 of 18/35 </span>is 2/7, so Lindaread<span> 2/7 of the </span>book<span> ...</span>
