Answer: It would be 28%.
Step-by-step explanation:
16x
Both of these expressions are similar expressions, therefore you can simply add the number in front of the 'x'
6 + 10 = 16
Therefore, 6x + 10x = 16x
No spaces? like t h i s? or like thiiiss??? is this bugging you ????
anyway
use elimination
multiply secn equation by -1
-3x-2y=-6
add to other equation
-3x-2y=-6
<u>4x+2y=10 +</u>
1x+0y=4
x=4
sub back to solve for y
3x+2y=6
3(4)+2y=6
12+2y=6
minus 12 both sides
2y=-6
divide 2
y=-3
(4,-3)
The result we would get when we simplify 5x/(x + 1) - (x - 4)/(x + 1), is 4.
<h3>How to Simplify an Expression?</h3>
Given the following expression:
5x/(x + 1) - (x - 4)/(x + 1), the first step to take is to find the common denominator.
The common denominator of the given expression is: (x + 1). Therefore, the expression would be simplified as shown below:
[1(5x) - 1(x - 4)] / (x + 1)
Evaluate the numerator
(5x - x + 4) / (x + 1)
Combine like terms in the numerator
(4x + 4) / (x + 1)
4(x + 1) / (x + 1)
Divide the numerator and denominator by (x + 1)
= 4
Therefore, the result we would get after simplifying the expression, 5x/(x + 1) - (x - 4)/(x + 1), is 4.

Answer:
... 0.7 . . . or 0.67 . . . or 0.667 . . . or 0.6667 . . . or ...
Step-by-step explanation:
2/3 is a repeating decimal: 0.66666... Round where you like. The rounding is usually in the 2nd or 3rd decimal place, depending on the accuracy needed.
... 0.67 or 0.667 . . . . . the decimal fraction of dogs
_____
<em>Comment on wording</em>
The question asks for the "number of dogs". In the problem statement, we're told that number is 2 (out of 3). Actually, it can be any even integer number (out of 3/2 that many), up to 2/3 of the total dog population (which is estimated at over 520 million).
Had the problem asked for <em>the fraction of dogs</em>, then an appropriate answer is 0.67.
