Answer:
Infinitely many solutions
Step-by-step explanation:
When the solved system has the same number on each side, the system has infinite solutions.
Simplify
-0.75x + 8 + 1.5x + 4.4
Collect like terms
(-0.75x + 1.5x) + (8 + 4.4)
Simplify
<u>0.75x + 12.4 </u>
Answer:
none
Step-by-step explanation:
Because X has the same coefficient on both sides but a different value is being added to it, there cannot be an solution.
9x+3=9x+5
-9x -5
-2=0, which doesnt work so theres no solution
Answer:
1100 cookies
Step-by-step explanation:
There are 3 types of cookies, the first represents 45% of the total, the second 25% and the last type there are 330. We can pose the following equation:
0.45 * x + 0.25 * x + 330 = x
solving for x:
x - 0.45 * x - 0.25 * x = 330
0.30 * x = 330
x = 330 / 0.3
x = 1100
which means that there are a total of 1100 cookies
