Question

-2a+3b-2a+3d-(-4d)+2a= 5/9+2/9+(-1/3)+1/9-(-(-2/3))= -6+(а-2)-(а-2)+7-(-(-(-8)))= 5+10в-(-10в)-(3+5-(-8))= решите пожайлуста!!!!!!!!!!!!

Answer 1

1. -2a+3b-2a+3d-(-4d)+2a=-2а+3в-2а+3д+4д+2а=3в+7д-2а

2. 5/9+2/9+(-1/3)+1/9-(-(-2/3))=5/9+2/9-1/3+1/9-2/3=8/9-1=-1/9

3. -6+(а-2)-(а-2)+7-(-(-(-8)))=-6+а-2-а+2+7+8=9

4. 5+10в-(-10в)-(3+5-(-8))=5+10в+10в-3-5-8=20в-11

Answer 2

-2a+7d+3b

-1/9

9

20в-11

Answer 3

To solve the given expression, let's break it down step by step: 1. Simplify the expression -2a + 3b - 2a + 3d - (-4d) + 2a: - Combine like terms: -2a - 2a + 2a + 3b + 3d - (-4d) - Simplify: -4a + 3b + 7d 2. Simplify the expression 5/9 + 2/9 + (-1/3) + 1/9 - (-(-2/3)): - Combine like terms: 5/9 + 2/9 + 1/9 + (-1/3) + 2/3 - Simplify: 8/9 + (-1/3) + 2/3 - Combine fractions with the same denominator: 8/9 + 1/3 - Convert 1/3 to have a denominator of 9: 8/9 + 3/9 - Simplify: 11/9 3. Simplify the expression -6 + (a - 2) - (a - 2) + 7 - (-(-(-8))): - Simplify the double negative: -6 + (a - 2) - (a - 2) + 7 - 8 - Combine like terms: -6 + 7 - 8 - Simplify: -7 4. Simplify the expression 5 + 10b - (-10b) - (3 + 5 - (-8)): - Simplify the double negative: 5 + 10b + 10b - (3 + 5 + 8) - Combine like terms: 5 + 10b + 10b - 16 - Simplify: 20b - 11 Therefore, the simplified expression is -4a + 3b + 7d = 11/9 - 7 + 20b - 11.
