Answer:
another number =27
Step-by-step explanation:
Let X stand for the larger number. The smaller number is therefore X - 13. We can now write the sum of the two numbers as:
X + (X - 13) = 4
X + X - 13 = 41
Gather the X’s and rewrite as,
2X - 13 = 41
Add 13 to both sides to get
2X = 54
Divide both sides by 2 to solve for X,
X = 27
There is more than one solution. For example we could take:
and
Then:
The answer is: 18° .
__________________________________________________
Explanation:
________________________________
x + 4x = 90 ; solve for "x"
____________________________
5x = 90 ;
____________________________
Divide EACH SIDE of the equation by "5"; to isolate "x" on one side of the equation; and to solve for "x" ;
___________________________________________________
5x / 5 = 90 / 5 ;
___________________________________________________
x = 18 ; The answer is: 18° .

Answer:(−∞,-13)
Step-by-step explanation:
solve for x the convert to interval notation
<em>x<-13 → </em>(−∞,-13)

Since it's a < and not a ≤ you use a parentheses instead of a bracket
Answer:
−x^3−x+2 / x^2
Step-by -step explanation:
2/x² - x - 1/x
= −x^4−x^2+2x / x^3
= −x^3−x+2 / x^2
