to blue, how many red balls are there if 80 blue
balls are in the box?
a. 40
b. 60
The correct option is b. 60 if there are 80 blue balls by setting up a proportion using the given ratio and the number of blue balls.
To find the number of red ball to determine the ratio between red and blue balls. In this case, the ratio is 3:4 (red to blue).
Let x represent the number of red balls.
The proportion can be set up as
(3/4) = x/80.
Cross-multiplying gives:
4x = 3 * 80,
which simplifies to
4x = 240.
Dividing both sides of the equation by 4,gives:
x = 60.
Therefore, there are 6in the box by using ratio and proportion

please help meeeeeee
Answer:
6
Step-by-step explanation:
8(1/4) is 2 bc 1/4 of 8 is 2
2-1=.5(10)
.5 works like 1/2 so 1/2 is 10 is 5
then you get 2-1+5 then after that you get 6
substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement
Answer:
B
Step-by-step explanation:
When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)
