Answer:
substitute x as 3
Step-by-step explanation:
f (3)=2x
=2×3
=6
There are 2 ways to do this. I'm going to do it the way that I think is most simple.
You have to find their LCM which is 40. Now times 40 to 1/4 v and 7/10
The equation then becomes 10+40v=28
You simplify it: 40v=18
v= 9/20
Answer:
The statistical question should be
"how many minutes do I exercise on each day of the week" and "how many minutes do I exercise each day of the week whilst there is background music"
Step-by-step explanation:
Here we have the non statistical question, how many minutes do I exercise each day
We note that a statistical question is one in which there are are different variety answers, where the distribution and the inclination of the the answers is sought
Therefore, statistically, we should ask, "how many minutes do I exercise on each day of the week" or "how many minutes do I exercise each day of the week whilst there is background music".
Answer:
y = -6
Step-by-step explanation:
Answer:
X=151
Step-by-step explanation:
1. 61+90= 151
-Combine the two given angles
2.180-151= 29
-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.
-29 is your difference which is also the angle next to X.
3.180-29= 151
-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.
-Therefore X=151
