Answer: The answer would be No, Yes, No.
Step-by-step explanation:
Look at the grid, you can see that it has 100 units in all.
0.42 equals 21/50, so they are both wrong. The denominator would have to be 100. The only logical one would be the second one.
Matrix A was expressed in the form of a 2x2
i'm not sure if this helps or not but here you go
We'll use elimination for this system of equations. What variable should get canceled? The x or y? Well to cancel, we need a positive and negative variable.
x + y = 10
x - y = 0
In this case, the y's will cancel out.
Then we will add the x's together and the 10 and 0.
x + y = 10
x - y = 0
Becomes
2x = 10
Now, solve for x. Just simply divide by 2.
2x / 2 = 10 / 2
x = 5
Now we know what the x variable is equal to!
To solve for the y variable, just replace the x variable in one of the equation and solve for y.
I'll use the x + y = 10 equation
We know x is equal to 5.
5 + y = 10
Subtract both sides by 5.
5 - 5 + y = 10 - 5
y = 5
So, both x and y are equal to 5.
y=29/5x your answer will be 0
554
17*32=554 554sq^2
Hope this helps :)
