Mathematics
1 answer:
Airida [17]2 years ago
7 0

Answer:

15

Step-by-step explanation:

Angle 2 is 2x+10

angle 4 is 4x+80

and from the figure we can understand that when we add these 2 equations

We get

6x+ 90= 180

6x = 180 - 90= 90

6x= 90

x = 90 ÷ 6 = 15

answer = 15

MATH HELP ASAP! PLEASE HELP! 20 POINTS!!
Aloiza [94]

The mean decreases, think about it, if every single value in a data set was decreased by the same number, the average would also go down by the same number

The median would also go down, because the value in the middle of the data set would now be smaller than before

The mode would also decrease, because the value that showed up the most in the data set has now also been decreased

The range, however, stays the same. If the lowest value in a data set was 3 and the highest was 10 and you subtracted 2 from each value in the data set, you would have the lowest at 1 and the highest at 8. But, 10-3 still equals 8-1, so the range is unchanged

Select the statement that correctly describes the expression below
Kitty [74]

Answer:

B

Step-by-step explanation:

The equation is (2x+5)^2.

It can't be A because 2 is the multiplier for only x.

It can't be C because the square is outside of the equation.

It can't be D because again, the square is outside of the equation.

So the only thing left is B.

Hope this helped!
