This would be 50 rounded to the nearest ten
Answer: 0.4x + 0.1
Step-by-step explanation: Distribution.
0.5(x+0.1)-0.1(x-0.5)
0.5 times x = 0.5x
0.5 times 0.1 = 0.05
First step: 0.5x + 0.05
Distribute next part
-0.1 times x= -0.1x
-0.1 times -0.5 = 0.05
-0.1x + 0.05
Put together: 0.5x + 0.05 -0.1x + 0.05
Combine like terms:
0.5x -0.1x = 0.4x
0.05 + 0.05 = .1
Answer: 0.4x + 0.1
Answer:
70 degrees
Step-by-step explanation:
Complementary angles sum up to 90.
To find the larger angle, you find the total of the values in the ratio, divide the larger value of the ratio by the total and multiply it by 90.
(7/7+2)×90=7/9×90
=7×10
=70
OR
Write an equation:
7x+2x=90
9x=90
x=10
Then multiply x by the larger value.
7x=7 (10)=70
I think, this is how it works, there are as you've probably heard triangles called special right triangles, there are either 45,45,90 (the interior angles) or 30,60,90, so that being said the largest side is opposite the largest angle, smallest side opposite the smallest angle so on so forth, so that is a 30,60,90 triangle bc 2 sides would have to be the same I think ah I hope that makes sense I apologize if it's wrong best of luck
