The answer is 15. If you subtract 5-15 you get -10 and add 6 is -4
Answer:
The perimeter of the rectangle is 54 meters.
Step-by-step explanation:
In order to find the perimeter of the rectangle, which is the sum of all the sides, we need to know not only the length, but also the width. The formula for area of a rectangle is A = length x width. Setting up an equation to find width 'w', we get: 162 = 18 x w. Using inverse operations, we divide both sides of the equation by 18 to get w = 9. Since we now know that w = 9 and l = 18, we can find the perimeter using the following equation: P = 2w + 2l or P= 2(9) + 2(18) or P=54 meters.

The measure of ∠ADB will be 105°
<em><u>Explanation</u></em>
According to the below diagram, the angle bisectors of ∠A and ∠B are intersecting at point D.
Given that, the measures of
° and
°
So,
° and
°
Now in triangle ADB, <u>the sum of all three angles is 180°</u>
So, 
Thus, the measure of ∠ADB will be 105°
Answer:
275 is 30% of 916.67
Step-by-step explanation:
We have, 30% × x = 275
or 
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 275 ×
x = 916.67
If you are using a calculator, simply enter 275×100÷30, which will give you the answer.
