Step-by-step explanation:
Given
4x - 8x ÷ 2
Under the rules of PEMDAS , division must be performed before subtraction.
Hence
4x - 8x ÷ 2 = 4x - 4x ← dividing - 8x by 2, then
4x - 4x = 0 ← correct answer
Answer:
20g
since mass should be in kg or gram if small then g
2x+4=10
2x=6
x=3
2(3)+4= 10
(plus, on parallelograms like that, parallel sides are equal to each other)
X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
