The concept of being able to swap numbers in an addition sum is called the commutative property of addition.
20 + x = 55x = 55 -20x= 35
simply do addition and your answer comes out to be 246
(4 x 5) + (7 x 5) = 11 x 5 = 55
The GCF of 20 and 35 is 5. (4 x 5) + (7 x 5) = 11 x 5 = 55
The GCF of 20 and 35 is 5. That makes 20 + 35 (4 x 5) + (7 x 5) = 11 x 5, a needlessly complicated way of saying that 20 + 35 = 55
(510)+(55)
It is: 75-55+35 = 55
20+35+40+55+60+55+80=345
55+(-20) equals 35
20 x 35 = (20 x 30) + (20 x 5) = 600 + 100 = 700 20 + 35 = (4 x 5) + (7 x 5) = 11 x 5 = 55
Yes.
