The correct answer is D, 146 inches.
7 x 12 = 84
4 x 12 = 48
84+48+4+10 = 146
Answer: Choice A
Proof:
Replace x with 1 and y with 2. This is because (x,y) = (1,2) so x = 1 and y = 2.
Doing both replacements and simplifying leads to...
2*x - y = 0
2*1 - 2 = 0
2 - 2 = 0
0 = 0
That confirms (x,y) = (1,2) is a point on the line.
It confirms (1,2) is a solution to the equation.
I think the correct answer from the choices listed above is the second option. An equation sometimes has one solution. A system of equation can have one solution when the equations intersect at one point. Equations can also have two or more number of solutions.
Answer:
2 1/4 pies or 2.25
Step-by-step explanation:
3/4 = .75 = 75%
a whole pie is 100% or 1
3 took 3/4
so
3 x .75 = 2.25
lets break this answer down
if 1 is a whole pie then that would mean 2 would equal 2 whole pies
now with the left over .25 it would be 25% so 2 1/4
