Answer:
A = 16
Step-by-step explanation:
subtract .5 for both sides --> .25a = 4.5 - .5
.25a = 4
now divide .25 by both sides
A = 16
<span>The
problem wants us to find the number that the 21% is 42.
42 is the 21% of 200
How:
=> 21% = 21 /100
=> .21
In order to get the answer we need to find a number to be multiplied by .21 and
get 42 as result.
=> 50 x .21 = 10.5
=> 100 x .21 = 21
=> 150 x .21 = 31.5
=> 200 x .21 = 42
thus, 42 is the 21% of 200.</span>
X + y = 180°
x = 6 + 4y
6 + 4y + y = 180°
5y = 174°
y = 34.8
x = 6 + 4(34.8)
x = 145.2°
