Answer:
The Answer is D
Step-by-step explanation:
The first question's answer is 80% because 100-20 is 80.
The second question is There is not enough information to tell because it doesn't give an amount. It gives us percent so we can't tell how many people are in the survey.
Answer:
No
Step-by-step explanation:
Let's plug these measurements into the Pythagorean Theorem and determine whether the resulting equation is true or not:
4^2 + 55^2 = 73^2
16 + 3025 = 5329 This is false, and so:
A triangle with side lengths 73 inches, 55 inches and 4 inches is NOT a right triangle.
The part the it is multiplying by the placholder (not adding)
example
2+4x
4 is placeholder, 2 is not
x and y are placeholders
5/3 is not
5/3 is the coefient
Answer:
7x+3y
Step-by-step explanation:
- Collect like terms
(3x+4x)+(-5y+8y)+(x^2-x^2)
2. Simplify
3x+4x=7x
-5y+8y=3y
x^2-X^2=0
So you get 7x+3y as your final answer
