Answer:
38
Step-by-step explanation:
The range of a data set is the smallest number subtracted from the largest number.
In this data set, the largest number is 43 and the smallest number is 5.
Therefore, 38 is the range of this data set.
If you expand this equation first
You get -4u+6+3u=3u+24
And if you simplify that you get:
-u+6=3u+24
Now you need to solve this equation to find u
First bring 3u to the other side to -u-3u (the positive changes to negative)
Now the equation is
-4u+6= 24
Take 6 of both sides
-4u=24-6= 18
-4u= 18
So u= -18/4
Which simplifies to -9/2
Answer: -9/2
Well... 2/5 of 35 is 14.
With this information we can determine the final answer. This means 21 students are boys.
Your answer is 21.

Answer:
∠2 = 115.5°
Step-by-step explanation:
128.5° is an exterior angle of the triangle
The exterior angle equals the sum of the 2 opposite interior angles, hence
∠2 + 13 = 128.5 ( subtract 13 from both sides )
∠2 = 115.5°
