<h3>
Answer: -3.33</h3>
==========================================================
Explanation:
Everywhere you see an x, replace it with -4. Then apply the order of operations PEMDAS to evaluate.

9/10 = 90/100, so 90/100 (which is 9/10)+ 9/100 = 99/100
Answer:
<em>4.9 - 4n</em>
Step-by-step explanation:
Given the expression;
2.4 - 5.5 -4n + 8?
Collect like terms;
2.4 - 5.5 -4n + 8?
2.4 - 5.5 + 8-4n
-3.1 + 8 - 4n
<em>4.9 - 4n</em>
<em></em>
<em>Hence the simplified form of the equation is 4.9 - 4n</em>
Each of the input changes is 1 unit.
Each of the output changes is 3 units, so the function is linear with a slope of 3.
The output is -2 when the input is 0, so the function is
.. y = 3x -2
6400/8=800, this leaves 800g of sugar per person.
800*10= 8000
So this family is entitled to 8000g of sugar
