Answer:
x=5
Step-by-step explanation:
x+7=12
x=12-7
x=5
This is the concept of algebra, we are required to find the value of the variable a, given that M lies between L and N.
LM=8a=56
Therefore solving the above we get:
8a=56
dividing both sides by 8 we get:
(8a)/8=56/8
a=7
Given that MN=7a
Then;
MN=7*7=49
Thus
LN=56+49=105
Thus;
a=7 and LN=105
The average rate of a body is the total distance travelled divided by the total time.
<em>The cheetah runs at an average rate of 50.91mph, not 55mph</em>
Let
<em /><em> distance</em>
<em /><em> average rate</em>
<em /><em> time</em>
<em />
We have:
The average rate of the trip is:
Where
<em /><em> the total distance from A to B and back to A</em>
and
<em /><em> total time spent from A to B and back to A</em>
becomes
Recall that:
Make the subject
Substitute in
Factor out t1
Substitute values for r1 and r2
Hence
- <em>The equation of the average rate is: </em><em>.</em>
- <em>The average rate is 50.91mph, not 55mph</em>

Answer:
The road running along the third side was 3 miles long.
Step-by-step explanation:
Given,
Length of hypotenuse =
Length of one leg =
We have to find the length of the third side.
Solution,
Since the field is in the shape of a right triangle.
So we use the Pythagoras theorem to find the length of the third side.
"In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of other two sides".
On framing in equation form, we get;
Where 'a' = 1st side of right triangle
'b' = 2nd side of right triangle
'c' = hypotenuse
Now we put the given values and get;
Now taking square root on both side, we get;
Hence The road running along the third side was 3 miles long.
