This is system of Equations.
<span>2x + 3y =10
x + y = 3
</span>
x + y = 3 (multiply this by three) to get 3x + 3y = 9
2x + 3y =10
3x + 3y = 9 Subtract them
-1x = 1
x=-1
Now plug x back into the top equation and solve for y.
I hope this helps! If not, let me know! Have a fantastical day!
Answer:
2.33 units
Step-by-step explanation:

1/2 * 1/4 = 1/8
3/8 * 2/3 = 1/4 same for back left fin
2/5 *1/2 = 1/5
2/3 *1/2 = 1/3
1/4 + 3/4 = 8/8
2/3 +1/6 = 5/6
4/5 +1/5 = 4/4
1/4 +1/5 = 9/20
front/back right fin = 3/8
x+ 1 2/3..... = 4/5
The Law of Cosine states
cos

so plugging in the numbers gives us
cos

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos

rounding your answer will give you 34°
Answer: 6.89
Step-by-step explanation:
9x+53>= 115
Subtract 53 from both sides
9x+(53-53) >115-53
9x>62
Divide both sides by 9.
9x÷9>62÷9 = 6.889
