the question is false
Step-by-step explanation:
0.25=-4.5+1.28 add -4.25 and 1.28 to get -2.97
0.25=-2.97 compare 0.25 and -2.9
We know that

by using proportion

the answer is
Answer:
9
Step-by-step explanation: Y=mc^2
Answer:
Step 1 : Multiple both sides by 2
3x + 2y = 1
4x - 2y = 20
Step 2 : Eliminate 1 variable by adding the equations
7x = 21
Step 3 : Divide both sides by 7 to solve for x
x = 3
Step 4: Substitute the value of x into 3x + 2y = 1
3(3) + 2y = 1
Step 5: Solve for y
2y = 1 - 9
2y = -8
*divide by 2
y = - 4
Solution:
(x,y) = (3, -4)
