Answer:

Question 1

<u>Given</u>

  • SP = 144
  • P = 20%
  • CP = x

<u>Use formula and solve for x:</u>

  • SP = CP + P
  • 144 = x + (20% of x)
  • 144 = x + 0.2x
  • 144 = 1.2x
  • x = 144/1.2
  • x = 120

Cost price is N 120

Question 2

<u>Given</u>

  • SP = 1000
  • P = -20% (negative because of loss)
  • CP = x

<u>Use formula and solve for x:</u>

  • SP = CP + P
  • 10000 = x - (20% of x)
  • 10000 = x - 0.2x
  • 10000 = 0.8x
  • x = 10000/0.8
  • x = 12500

Cost is N 12500

RS=4y+4, ST=3y+4, and RT=43 <br> What is the value of y?
Shkiper50 [21]

The value of y is 5

<h3>How to determine the value </h3>

From the given line, it can be concluded that:

The segment RT is divided into RS and ST

But we have the following parameters

The length of the sides are:

  • RS=4y+4
  • ST=3y+4
  • RT=43

Since RT is RS added to ST:

We have;

RT = RS + ST

substitute the values

43 = 4y + 4 + 3y + 4

collect like terms

43 = 4y + 3y + 4 + 4

Add like terms

43 = 7y + 8

43 = 7y + 8

Make '7y' subject of formula

7y = 43 - 8

7y = 35

Make 'y' the subject of formula

y = 35/ 7

y = 5

Thus, the value of y is 5

Find the value of Z for the triangles
kolbaska11 [484]

Answer:

z = 17.5

Step-by-step explanation:

segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

\frac{RS}{RT} = \frac{SX}{TX} , substitute values

\frac{15}{z} = \frac{6}{7} ( cross- multiply )

6z = 105 ( divide both sides by 6 )

z = 17.5

The perimeter of a triangle is 6x. One side is x+3 and another side is 2x+4. What is the length of the 3rd side?
maxonik [38]
Let y = the length of the 3rd side
x+3 + 2x+4 + y = 6x
x + 2x + 3 + 4 + y = 6x
3x + 7 +y = 6x
7 + y = 3x
y = 3x - 7
The length of the third side in terms of x is 3x-7

X/6 = 10/9<br> improper fraction in its simplified form
FinnZ [79.3K]

Answer:

\frac{x}{6}  =  \frac{10}{9}  \\   \therefore \: 9 \times x = 6 \times 10 \\ \therefore \:9x = 60 \\ \therefore \:x =  \frac{60}{9}  \\ \therefore \:x =  \frac{20}{3}  \\   \:  \:  \:  \:  \:  \: \huge \red{ \boxed{\therefore \:x =  6\frac{2}{3} }}
