Q bisects PR. If PR=28, and PQ = 2x+5, what is the value of x?

Mathematics
1 answer:
Veseljchak [2.6K]2 years ago

Answer:

x = 4.5

Step-by-step explanation:

Given

PR = 28

PQ = 2x + 5

Required

Find x

Since Q is a bisector of PR; This mean PR is divided into exactly two equal parts;

Hence:

PR = 2 * PQ

Substitute values for PR and PQ

28 = 2 * (2x + 5)

Divide both sides by 2

\frac{1}{2} * 28 =\frac{1}{2} * 2 * (2x + 5)

14 = 2x + 5

Solve for 2x

2x = 14 - 5

2x = 9

Solve for x

x = \frac{9}{2}

x = 4.5

Before being simplified, the instructions for computing income tax in Country R were to add 2 percent of one’s annual income to
Vedmedyk [2.9K]

Answer:

Option C)

50 + \dfrac{I}{40}          

Step-by-step explanation:

We are given the following in the question:

I is the annual income of a person in a country R

2 percent of one’s annual income =

\dfrac{2}{100}\times I = 0.02I

1 percent of one’s annual income =

\dfrac{1}{100}\times I = 0.01I

Average of  100 units of Country R’s currency and 1 percent of one’s annual income.

=\dfrac{0.01I + 100}{2}

Income tax =

2 percent of one’s annual income + Average of  100 units of Country R’s currency and 1 percent of one’s annual income.

= 0.02I + \dfrac{100+0.01I}{2}\\\\=50 + \dfrac{0.04I + 0.01I}{2}\\\\=50 + \dfrac{0.05I}{2}\\\\= 50 + \dfrac{I}{40}

Thus, income tax is given by

Option C)

50 + \dfrac{I}{40}
