Given that 5W = 2P + 3R find the value of P when W = 4 and R = −4

Olenka [21]

Answer:

P = 16

Step-by-step explanation:

Given

5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation

5(4) = 2P + 3(- 4), that is

20 = 2P - 12 ( add 12 to both sides )

32 = 2P ( divide both sides by 2 )

16 = P

Manas receives a commission of Rs.5,000 on sales of Rs.65,000.How much commission will he get on sales of Rs.20,000.

tangare [24]

$\\
\text{Let Manas receives a commission of Rs. 5000 on sales of Rs. 65000}\\
\\
\text{We need to find how much commision he will get on the sale of Rs.20000}\\
\\
\text{To find the commision, we use the unitary method.}\\
\\
\text{On sales of Rs. 65000, Manas receives a commision of}=5000\\
\\
\text{so on sales of Rs. 1, Manas will receiv a commision of}=\frac{5000}{65000}\\
\\
\text{Hence on sales of Rs. 20000, Manas will receiv a commision of}\\
\\=\frac{5000}{65000}\times 20000\\
\\
=1538.46$

Hence, on the sales of Rs. 20000, Manas will receive a commission of: Rs. 1538.46

A triangle with the coordinates (6,4), (2,-1), and (-3,5) is translated 4 Units left and rotate 180 degrees about the origin. Wh

ankoles [38]

Answer:

(-2,-4),(2,1), and (7,-5)

Step-by-step explanation:

The given triangle has coordinates (6,4), (2,-1), and (-3,5).

When we translate 4 units left, the we obtain:

(6,4)------>(6-4,4)=(2,4)

(2,-1)----->(2-4,-1)=(-2,-1)

(-3,5)----->(-3-4,5)=(-7,5)

When the resulting figure is rotated 180° about the origin, the coordinates of the final figure becomes

(2,4)------>(-2,-4)

(-2,-1)----->(2,1)

(-7,5)------->(7,-5)

NB: The mapping for 180° rotation is:

(x,y)----->(-x,-y)

Please help! The expressions 3x - 9 and 23 - 5x represent the lengths (in feet) of two sides of an equilateral triangle. Find th

valentina_108 [34]

An equilateral triangle has 3 congruent sides so the 2 expressions above are equal
3x - 9= 23 - 5x
And then you solve for x
-22=-2x
X=11
