Answer:
10000
Step-by-step explanation:
X+7=-8
You are trying to get x on its own so you will subtract 7 from both sides.
x+7-7=-8-7
This simplifies to x= -8-7
A negative plus a negative equals a negative. So -8-7 equals -15
Your final answer is x=-15
Answer:
<em>Vectorial Mechanics is a book on vector manipulation by Edward Arthur Milne, a highly decorated British astrophysicist and mathematician. </em>
Step-by-step explanation:
<h2 /><h2><em>•</em><em>|</em><em> </em><em>jess </em><em>bregoli</em><em> </em><em>|</em><em>•</em><em> </em></h2>

<span><span>K = k + 13</span><span>78</span></span>
Cross multiply:
K * 8 = 7 * k + 13
Simplifying
K * 8 = 7 * k + 13
Reorder the terms for easier multiplication:
8K = 7 * k + 13
Reorder the terms:
8K = 7 * 13 + k
8K = 13 * 7 + k * 7
8K = 91 + 7k
Solving
8K = 91 + 7k
Solving for variable 'K'.
Move all terms containing K to the left, all other terms to the right.
Divide each side by '8'.
K = 11.375 + 0.875k
Simplifying
K = 11.375 + 0.875k
there it was hard but i got it
