Answer:

Step-by-step explanation:

4x-3y=-1 ...(1)  

2x+3y=13..(2)

add (1) and (2) : 4x-3y + 2x+3y = -1 +13

6x =12

x = 12/6 = 2

put x = 6 in (2) : 2(2)+3y = 13

4+3y =13

3y =9

y=3

Find the Perimeter of this shape. Can someone explain to me how to find the perimeter.
Agata [3.3K]
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm

Solve the system of equations.<br><br>- 9x + 4y = 6<br><br>9x + 5y = -33​
liubo4ka [24]

Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get

9x + 5y - 9x + 4y = -33 + 6

9y = -27

y = -3

Substituting this value of y in the first equation, we get

-9x + 4(-3) = 6

-9x - 12 = 6

9x + 12 = -6

9x = -18

x = -2

Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.

Unlikely

Step-by-step explanation:

The probability of picking a number divisible by 5 is 2/12 or 1/6. So its pretty unlikely.
