The property that allows 7 + 9 + 3 = 7 + 3 + 9 is called the Commutative Property of Addition and Multiplication. This means that as long as the sign is either a multiplication symbol or an addition symbol, we can move (or "commute") the values wherever we want and the expression will still equal the same amount.
Hope that helped =)
Answer:
A) 5x-7y=42
Step-by-step explanation:
We know that 5 x 7 = 35 then add 7 = 42
We divide 5 and 7 by 5/7
5/ 5/7 = 0.1
7/ 5/7 = 0.2
We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5
We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.
We then use 7 for y and keep 5 for x.
2/8, 2 Over 8 because all your doing is multiplying 1x2 and 4x2
m < DAB + m < ADC = 180 (because ABCD is a parallelogram)
so m < ADC = 180 -112 = 68 degrees
Therefore m < ADB = 68 - 27 = 41 degrees (answer)
Answer:
34.85%
Step-by-step explanation:
Let w be the probability of winning, then probability of losing would be (1 - w)
We know the ratio of winning to losing is 0.535
w/(1 - w) = 0.535
w = 0.535 - 0.535w
1.535w = 0.535
w = 0.348534202
% of games won:
0.348534202 × 100
34.8534202%
