Answer:
The equations are:
and 
Step-by-step explanation:
Given
Represent bones eaten Today with T and yesterday with Y
Required
Write the equation
In the first statement, we have that:

Reading further; In the second statement

Hence, the equations are:
and 
Solving further:
Substitute 2Y for T in the second equation


Divide both sides by 4


Recall that



For this case what you should do is use the following trigonometric relationship
senx = (1200) / (2400)
senx = 0.5
Clearing the angle we have
x = ASIN (0.5)
x = 30
Answer:
The angle of elevation from the base to the top of the mountain is 30 °
6x+7y=4x+4y6x+7y=4x+4y6, x, plus, 7, y, equals, 4, x, plus, 4, y Complete the missing value in the solution to the equation. ((l

Answer:
<h3>
The missing value in the solution to the equation is <u>
6</u>
.</h3><h3>
So, the complete solution is (6, -4).</h3>
Step-by-step explanation:
Given:
6x+7y=4x+4y.
( ,-4)
Now, to complete the missing value in the solution to the equation.
<em>As, the equation is:</em>
<em />
<em />
<em>And, the solution is:</em>

Now, solving the equation by putting the value of
:

<em>Adding both sides by 28 we get:</em>
<em />
<em />
<em>Subtracting both sides by </em>
<em> we get:</em>
<em />
<em />
<em>Dividing both sides by 2 we get:</em>

<u><em>Thus, the solution to the equation is (6, -4).</em></u>
Therefore, the missing value in the solution to the equation is <u>6</u>.
To determine whether the corresponding terms of 2 arithmetic sequence's added will give new arithmetic sequence or not, Let' take 2 Arithmetic sequences.
In one first term is a1 and common difference is d1, in the other first term is a2 and common difference is d2.
Now nth term for first sequence = a1+(n-1) d1
nth term for second sequence = a2+(n-1) d2
Now add the 2 terms: a1+(n-1)d1 +a2 +(n-1)d2
= a1+a2 + (n-1)(d1+d2)
This is again new arithmetic sequence with first term a1+a2 and common difference d1+d2.
Hence if we add corresponding terms of 2 arithmetic sequence, we will again get an arithmetic sequence.
Let us say that S is the total food sales therefore we can
create the following equation:
0.20 S = 625 + 0.10 S
Solving for S:
0.10 S = 625
S = 6250
<span>Therefore the food sales should amount to $6,250</span>
