There are 5 variables in the expression. the answer is 5
Answer:
I'm guessing 6
Step-by-step explanation:
It's probably wrong.. Sorry :(
3/24 = 7/x
Solving:
Use cross multiplication
3x = 168
Isolate x by dividing 3 from both sides:
x= $56
n - the first number
n + 11 - the second number
2n + 6 - the third number
81 - the sum of three numbers
The equation:
n + (n + 11) + (2n + 6) = 81
n + n + 11 + 2n + 6 = 81 <em>combine like terms</em>
(n + n + 2n) + (11 + 6) = 81
4n + 17 = 81 <em>subtract 17 from both sides</em>
4n = 64 <em>divide both sides by 4</em>
n = 16
the largest of the tree numbers is the third number 2n + 6.
Substitute the value of n:
2(16) + 6 = 32 + 6 = 38
<h3>Answer: 38</h3>
Answer:
lim
x->3. 3×(3) Sq. -4×3-15
------------------------
(3) Sq. +3-12
lim
x->3. 3×9-12-15
---------------
9+3-12
lim
x->3. 0/0(which is in determinant form)
