Given:
The compound inequality is:
To find:
The solution for x.
Solution:
We have,
To solve the inequality, we need to isolate the variable x.
Subtracting 3 from each side, we get
The solution for x is . Therefore, the correct option is C.
Answer:
sum of all angle of triangle is equal to 180 degree
X + 34 + 31 =180
x+65=180
x=180-65
x=115
Answer:
13 and 16.
Step-by-step explanation:
Let the 2 parts be x and y, then:
x + y = 29
x^2 + y^2 = 425
From the first equation y = 29 - x so substituting in second equation, we get:
x^2 + (29 - x)^2 = 425
x^2 + 841 - 58x + x^2 - 425 = 0
2x^2 - 58x + 416
x^2 - 29x + 208 = 0
208 = 2*2*2*2*13
= 16 * 13
So factoring we get:
(x - 13)(x - 16) = 0
x = 13 ,16
So the numbers are 13 and 16.
