Answer:
6:5:2
Step-by-step explanation:
We need the amounts for v to be equal, so
u:v = 12:10 v is 10
v:w = 25:17 v is 25
Multiply the first ratio by 2.5 to get an equivalent amount for v
u:v = 30:25
so u:v:w = 30:25:10
They can all be divided by 5
6:5:2
A: highest and lowest time surfing the internet
What the look at on the internet
B: 40 to 60 minutes
It represents the middle half of the students in the class
C: there should be no significant effect on the interquartile range if there is an outlier. The graph as a whole would have longer “whiskers” though.
Using the Pythagorean therefrom none of these are correct <span />
Answer:
The last one: 25%
Step-by-step explanation:
Since one equation has a positive y and the other a negative y we can simply add the two equations together to solve for x...
(4x-y=5)+(3x+y=16)
7x=21,
x=3, now you can use either original equation to solve for y...
3x+y=16 becomes:
3(3)+y=16
9+y=16
y=7
So the solution is the point (3,7)
