Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-
We then solve 5
y=-1 *Substitute the value of "y"
x= -
x=-2
This works.
Answer:
11
Step-by-step explanation:
Evaluate using
PEMDAS
First we do what is inside of the Parenthesis 12 - 9 = 3
Now we have 2 + 3²
Next is Exponents 3² = 9
Now we have 2 + 9
there is no multiplication or division needed so we go straight to addition
9 + 2 = 11
So we can conclude that the answer is 11
The park formed like a rectangle so :
Area = length × width
Area = ( 9/10 ) × ( 4/5 )
Area = 9 × 4 / 10 × 5
Area = 9 × 2 × 2 / 5 × 5 × 2
Area = 18 / 25
0.75 = 3/4
3/4 is your anwer
Not 100% sure this is right but
