Answer:
D) 3
Step-by-step explanation:
-3x+6=2x-9
<em>subtract 6 from both sides</em>
-3x=2x-15<em> </em>
<em>subtract -2x from both sides</em>
<em>-5x = -15</em>
<em>divide both sides by -5</em>
x= 3
She is losing $20, so it indicates a negative number when really it is positive
Answer:
x = 43/2 = 21.5
Step-by-step explanation:
2x - 12 + 4x + 12 + 2x + 8 = 180 (Combine Like terms)
8x + 8 = 180
43/2 = 21.5
1) 78.5/pi = 25
radius = 5
The one 5 digits away from that coordinate is (2,-1)
2) This question is area, not perimeter. The width and length has to be added by 4 because of 2 feet on both sides.
9*10 = 90 - 30 = 60
3) 25pi according to pythagorean theorem.

Explanation:</h2><h2 />
From this exercise, we know that a biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months:
At the beginning of her study the month can be represented by and at the end of the study the length of the fish was approximately 6.86 cm, so substituting this value into the equation we get the month at which the length was 6.86 cm:
So a reasonable domain is the set of m-values for which the function is defined:
In other words, the study lasts three months.
