1) solve for x by multiplying each equation with the opposite number and making one a negative

-4(5x + 2y =-9)-4
5(4x +3y = 25)5

2) multiply on both sides of equal sign

-20x - 8y = 36
20x + 15y = 125

3) add all the like terms to get new equation

7y = 161

4) simplify

7y = 161
/7 /7

y = 23

5) make ordered pair and then input 23 into original equation

( x , 23)

5x + 2y = -9
5x + 2(23) = -9
5x + 46 = -9
-46 -46
5x = -55
/5 /5

x = -11

6) input to ordered pair

(-11, 23)

7) Thats your answer!

Romashka-Z-Leto [24]

Answer:

1947 units^2

Step-by-step explanation:

you can split it up into different sections of rectangles.

the first one is 25x39= 975

The second section is the connector which you do

43-25=18

and you do 39-27=12 and then

you multiple 18x12 which equals 216

and the final section you do 24+12=36

and 36x21=756

and finally you add them all up to equal 1947 units^2

In a quiz-based program, there are three teams A, B and C. There is a total of five rounds in a game; 20 marks are given for eac

9966 [12]

From the given scenarios, the positions of winning of each team is; Team C came first, Team A came second and Team B came third

<h3>How to find probability of winning?</h3>

From the question, we can derive the following;

Marks gained by team A = 3 × 20 = 60 marks

Marks deducted = 2 × 10 = 20 marks

Hence;

Total marks for Team A = 60 - 20 = 40 marks

Marks gained by team B = 2 × 20 = 40 marks

Marks deducted = 2 × 10 = 20 marks

Hence, total marks of team B = 40 - 20 = 20 marks

Marks gained by team C = 3 × 20 = 60 marks

Marks deducted = 1 × 10 = 10 marks

Hence, total marks of team C = 60 - 10 = 50 marks

Thus, we can conclude that;

Team C came first, Team A came second and Team B came third
