Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

X-2y=1
X=1+2y

2(1+2y)+3y=-12
2+4y+3y=-12
2+7y=-12
7y=-12-2
7y=-14
y=-2

x-2*-2=1
x-(-4)=1
x+4=1
x=1-4
X=-3

Answer:

Therefore the value of given expression when r = 14 and s = 8 is

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s=11$

Step-by-step explanation:

Given:

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s$

To Find:

Value of above equation when r = 14 and s = 8

Solution:

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s$ .............Given

Put,

$r=14\\s=8$

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s=\dfrac{3}{7}\times 14 + \dfrac{5}{8}\times 8$

Now 7 × 2 = 14 and 8 will cancel each other we get

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s=3\times 2 + 5=6+5=11$

Therefore the value of given expression is

$\dfrac{3}{7}\times r + \dfrac{5}{8}\times s=11$

The price of an item has risen to $207 today. Yesterday it was $180. Find the percentage increase

andriy [413]

Answer:

15% '

Step-by-step explanation:

Price yesterday = $180

Price today = $207

Increase in price = $(207 - 180)

=> $27

Percent increase =

Increase / Price of yesterday

=> 27 / 180 * 100

=> 3 / 2 * 10

=> 30 / 2

=> 15

15%

Therefore, the rise in the price of the item = 15%
