Answer:
156 degrees
Step-by-step explanation:
The four angles in any quadrilateral add to 360 degrees. Add the given degrees and subtract that number from 360 for your answer
7 * 0.5 + 3 * 0.8 = 3.5 + 2.4 = 5.9
<span>5.9/10 X 100 = 59%
</span><span>59% concentration of new mixture</span>
The very first one (the very left one)
so if you take away 1/4 from 3/4 you will get 2/4
3/4 - 1/4 = 2/4 or 1/2
so the male elephant weights 1/2 a ton more than the female
X-1/3 = y-2/4
4(x-1) = 3(y-2)
4x-4 = 3y-6
4x-3y = -2 --->1
4x +3y =8 ---->2
2-1 ; 6y = 10
y = 10/6 or 5/3
And 4x + 3(10/6) = 8
4x =3
X = 3/4
