Answer: 320 boys
Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)
720/9= 80
You would then take 80 and multiply it by 4 because that is the number representing the boys
80*4= 320
Hello there!
This is a conceptual question about quadratic functions.
Remember that a solution of ANY function is where it intersects the x-axis, so if the quadratic function intersects the x-axis TWO times, this means that there are TWO real solutions.
Here's a list of things to remember that will help you out for quadratic functions...
•if a quadratic function intersects the x-axis twice, it has two real solutions.
•if a quadratic function intersects the x-axis once, it has one real solution and one imaginary solution.
•if a quadratic function intersects the x-axis zero times, it has zero deal solutions and two imaginary solutions.
Please NOTE: If you want to know how many solutions a polynomial function has, look at it's highest exponent. If it is 2, then it has 2 solutions whether they be real or imaginary. If it is 3, then it has 3 solutions.
Also, if one of the factors are the same for a polynomial function, the way it hits the x-axis changes! This is just some extra information to help you in the long run!
I hope this helps!
Best wishes :)
Steps :-
■ Eliminate the equations (subtract them). You'll get the value of 1 variable.
■ Then substitute in another equation to get the value of the other variable.
Answer :-
■ x = -8 & y = 0

Answer:
The answer is= 119 Bushels and a half(119.5)
Step-by-step explanation:
Equation related to the problem= 220-(67/4)·T=bushels of Beans left
After 6 days=
220-(67/4·)6=bushels of Beans left
Bushels of beans left=119.5---> You need to change the dot for a fraction
119.5 is 119 bushes and a half so
The answer is= 119 Bushels and a half(119.5)
