Answer:
127°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180°(n - 2) ← n is the number of sides
here n = 5 ( Pentagon), hence
sum = 180° × 3 = 540°
To find the fifth angle subtract the sum of the 4 given angles from 540
angle = 540° - (156 + 72 + 98 + 87) = 540° - 413° = 127°
7/4(53) + 6
92.75 + 6
98.75
Each book costs $15. 90 divided by 6 is 15 which is also 90 over 6.
<span>So the question is what is 8/32 in the simplest form. To find out we need to simplify the fraction. In this case the nominator and the denominator are both multiple of 8 so the nominator is 8=1*8 and 32=4*8 so we can write (1*8)/(4*8) and we see that we can cancel out number 8 and get 1/4 which is the simplest form of the fraction. </span>
Answer:
the answer is B
Step-by-step explanation:
6w + 5 - 3w + 7
<h3>i) collect like terms</h3>
= 6w - 3w + 5 + 7
= 3w + 5 + 7
<h3>ii) add the numbers</h3>
= 3 w + 5 + 7
= 3w + 12
