Answer:
Option C is correct.
(1, 4)
Step-by-step explanation:
A system of equation is given :
2x + 3y =12 .....[1]
4x + 2y =10 .....[2]
Multiply equation [1] by 2 both sides we get;

Using distributive property i,e 
4x + 6y = 24 .....[3]
Subtract equation [2] from [3] to eliminate x we get;
4x + 6y - 4x - 2y= 24 - 10
Combine like terms;
4y = 14
Divide both sides by 4 we get;
y = 3.5
Substitute the value of y in equation [1] we have;
2x + 3(3.5) =12
2x + 10.5 = 12
or
2x = 12 -10.5
2x = 1.5
Divide both sides by 2 we get;
x = 0.75
Solution = (0.75 , 3.5)
Best estimate solution = (1, 4)
Therefore, the best estimate solution of the given system of equation is, (1, 4)

Answer:
7.4
Step-by-step explanation:
Gud luck on the rest of your school work :)
It would be greater, because 1 foot is equal to 12 inches. 8 times 12 is 96. Then 96 plus 6 inches in 102. So it would be greater.
