Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
Y=4/3 because if 3 goes to rhs is becomes divided by the number on the rhs so answer is 4/3
Answer:the independent variable is t
the dependent variable is d
Step-by-step explanation:
d is dependent on t to determine what it is going to be. t does not depend on anything to determine what it can be.
Answer:
The answer is most likely 5 shrimp eats 5 grams of food im one day,
Step-by-step explanation:
At an aquarium, a shrimp if fed 1/5 gram of food each feeding and is fed 3 times each day. <em>What is the constant of proportionality and what does it tell us about the situation?</em>
So, We know the shrimp is fed 1/5 gram of food each feeding, And we know the shrimp is fed 3 times each day.
Now, We need to answer the question, <u><em>What is the constant of proportionality and what does it tell us about the situation?</em></u>
<u><em /></u>
Then, That means '5, shrimp eats 5 grams of food in one day
' is correct.
