Answer 1

Explicație pas cu pas:

27. a+b+c/3 =2.6

c= a+ 2.28

c= b+ 3.66 ==> a+2.28=b+3.66

a-b = 3.66-2.28

a-b= 1.38 => b=1.38- a

a+1.38-a +a + 2.28/3 = 2.6

a + 3.66/3 =2.6

a +3.66= o.86

a= 0.86 - 3.66 = - 2.8

b= 1.38 + 2.8 = 4. 18

c = 4 .18 + 2.28

c = 6.38

28 . a + b + c /3 = 5

a+b/2 =6.125

b = a × 0.75

a + 0.75a /2 = 6.125

1.75 a = 3.06

a =1.74

b = 1.74 × 0.75 = 1.3

1.74 + 1.3 + c /3 = 5

2. 04 +c = 1.66

c = 1.66- 2.04 = - 0 .38
