Use elimination to solve the system of equations. 5x-2y=-3 4x-2y = -6

Effectus [21]

Answer:

x=3, y=9

Step-by-step explanation:

5x-2y=-3

4x-2y=-6

Then:

solve for y:

-2y=-6-4x

y=3+2x

Substitute y into either equation:

4x-2(3+2x)=-6

4x-6-4x=-6

-6=-6, use other equation

5x-2(3+2x)=-3

5x-6-4x=-3

x-6=-3

x=3

then:

y=3+2(3)

y=9

Y is directly proportional to x,<br> and y = 45 when x = $600...<br> Find y if x = $1000.

Paul [167]

Answer:

The Answer is: 75.

Step-by-step explanation:

Set up the equation:

45 / 600 = y / 1000

600y = 45 * 1000

600y = 45000

y = 45,000 / 600 = 75.

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain p

bagirrra123 [75]

Given,

CP of cosmetics = Rs 360 per dozen

SP of a pair of cosmetics = Rs 80

To find,

The gain percent

Solution,

1 dozen = 12 items

CP of 1 cosmetic = 360/12 = Rs 30

SP of 1 cosmetic = 80/2 = Rs 40

Profit = SP-CP

= Rs 40 - Rs 30

= Rs 10

Profit percentage is given by :

$\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%$

So, the profit percentage is 33.34%.
