Answer:
(-1, -2)
Step-by-step explanation:
4x - 7y = 10
3x + 2y = -7
The common multiple of the x coefficient is 12.
Multiple 3 to 4 to get 12; 4 to 3 to 12:
3(4x - 7y = 10)
4(3x + 2y = -7)
12x - 21y = 30
12x + 8y = -28
Subtract the two equations:
-29y = 58
y = -2
Substitute y = -2 to either 4x - 7y = 10 or 3x + 2y = -7. Typically, do the easier equation to solve:
3x + 2(-2) = -7
3x - 4 = -7
3x = -3
x = -1
The order pair solution is like a coordinate: (x, y)

The answer is 256.25
EXPLANATION
Let 
represent the number.
Then, 
We cross multiply yo obtain,
We now divide both sides by 16.
This will give us,
Therefore the number is 256.26
Answer:
The area is π= 3.14 approx
Hope it helps!
Step-by-step explanation:
Area of circle = πr^2
Radius= r = 1 unit
So area,
= 3.14*(r)^2
= 3.14*(1)^2
= 3.14*1
= 3.14 or π if you want the specific answer
Answer: 1.5 + 3 = 1.8
Step-by-step explanation: Add both sides.
