Answer:
240
Step-by-step explanation:
3 times 80 is 240 and 7 times 80 is 560. added together is 800. 800 is the total amount of people, so it works.
Answer:
diving the angle into two congruent angles
Step-by-step explanation:
bisecting an angle means dividing the angle into two equal parts
Answer:
a) x = 260
b) g = 218
c) z = 30
d) h = 5
Step-by-step explanation:
a) 
Predict a number; let's say x = 225

Too low; try with a higher number; let's say x = 270

Too high, we're closer.
x = 260

--------------------------------------------------------------------------------------
b) 
let's say g = 230

Too high. Try g = 221

We're almost there. Let's try with g = 218

----------------------------------------------------------------------------------------
c) 
Let's try with z = 15

Too low; try a higher number. z = 30

--------------------------------------------------------------------------------------------
d) 
Let's try with h = 6

Too high; let's try with h = 5

Binomial has two terms.
Here A and B contains two terms.
C and D polynomials.
Now, In A. 7x^3y-13x^4 Here the highest degree is 4, So exclude option A because it is given that the binomial degree is 3.
We have now option B -2xy^2 - 19. Here degree of binomial is 3.
Answer: Option B
The correct answer is x = 1/28y^2
