The first thing we must do for this case is to define variables.
We have then:
x: number of red flowers
y: number of yellow flowers.
We write the system of equations:
x + y = 75
y = 2x
Solving the system we have:
x = 25
y = 50
Answer:
there are 25 red flowers in Sakura's garden
Answer: Which statement is False
Step-by-step explanation:
proportional relationships
y ∝ x
=> y = kx
Comparing with line line of equation
y = mx + c
m = k , c = 0
Hence A proportional relationship must graph as a line
TRUE
at x = 0 , y = 0
Hence graph of a proportional relationship must pass through (0, 0).
TRUE
y = kx
=> y/x = k hence
Each point (or pair) in a proportional relationship must share the same ratio.
TRUE
Each point (or pair) in a proportional relationship must share the same difference.
FALSE
By solving a linear equation, we will see that Victor is 30 years old.
<h3>
How old is Victor now?</h3>
Let's say that Victor is x years old.
We know that 10 years ago, (x - 10), his age was half of what it will be in 10 years (x + 10).
Then we can write the linear equation:
(x - 10) = (x + 10)/2
Now we can solve that equation for x:
2*(x - 10) = x + 10
2x - 20 = x + 10
2x - x = 10 + 20
x = 30
So we conclude that Victor is 30 years old.

Step-by-step explanation:
Multiple times the segment
Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
