Again set a proportion
x/4=35.25/1
=x=4(35.25)
x=141
Therefore the boat traveled 141 kilometres.
The answer is C.
Angle a is 80, angle d is 100, angle c is 100
Answer:
+4
Step-by-step explanation:
-5 - (-9)
-5 + 9

If you would like to solve 2x + 5y = -13 and 3x - 4y = -8, you can do this using the following steps:
2x + 5y = -13 /*4
3x - 4y = -8 /*5
_______________
8x + 20y = -52
15x - 20y = -40
_______________
8x + 15x + 20y - 20y = -52 - 40
23x = -92
x = -92 / 23
x = -4
<span>3x - 4y = -8
</span>3 * (-4) - 4y = -8
-12 - 4y = -8
12 + 4y = 8
4y = 8 -12
4y = -4
y = -1
The correct result would be x = -4 and y = -1.
