Add 1/(x-8) to both sides
cross multiply or multply both sides by (5-x)(x-8)
5(x-8)=5-x
distribute
5x-40=4-x
minus x from both sides
4x-40=4
add 40 to both sides
4x=44
divide by 4
x=11

*BEST ANSWER WILL BE MARKED BRAINLIEST*<br><br> MNOP is a square. what are the value of t and f?
igomit [66]

For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.

Therefore, we have the following equations:

4t + 20 = 90\\7f + 6 = 90

From these equations, we can clear the values of the unknowns.

For equation 1 we have:

4t + 20 = 90\\4t = 90 - 20\\4t = 70

t = \frac{70}{4}\\t = 17.5

For equation 2 we have:

7f + 6 = 90\\7f = 90 - 6\\7f = 84

f = \frac{84}{7}\\f = 12

Answer:

The values of t and f are given by:

t = 17.5\\f = 12

Security deposit:  1300
Last month's rent:  1300
Broker fee:  12% of year's rent = 0.12(1300)(12) = 1872

He needs to run with approximately 6429 for a distance of 9 km

<h3>How to determine the number of strides?</h3>

The given parameters are:

Length of stride = 1.4 m

Distance for marathon = 9 km

The number of strides needed is then calculated as:

Number of stride = Distance for marathon/Length of stride

Substitute the known values in the above equation

Number of stride = 9km/1.4m

Convert km to m

Number of stride = 9000m/1.4m

Evaluate the quotient

Number of stride = 6428.57143

Approximate the estimate

Number of stride = 6429

Hence, he needs to run with approximately 6429 for a distance of 9 km
