The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.

To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.

the answer is a

7.5

a + c - b = 3 + 2 - 5 = 5 - 5 = 0

If: 3c = 6Then: c = 2

144 Formula: c= (a2)+(ab)

c+c+c=6 C=2 Because: 2+2+2=6

The Pythagoream Thereom is a^2 + b^2 = c^2. Written out it is a squared plus b squared equals c squared.

2 PbO + C -> 2 Pb + CO2

If 2b a plus c, then we can say that 3tan A 2tan c = 21.

a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)

7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2

The letter c is a variable. Since c appears in all three c+c+c=6, C has to equal the same number each time. So c equals 2!!!!

Because there is no way to define the divisors, the equations cannot be evaluated.

yes

-c + 2 = 5 -c = 3 c = -3

b = sqrt32 or 4 root 2

6 + 12 - 5 = 13

c= -2 2/7 OR -2.285714

a=24 b=16 c=18

2b+3c

b = 40 - a, c = 42 - a so b + c = 40 - a + 42 - a, ie 82 -2a = 34 so a = 48/2 ie 24 b = 40 - 24 ie 16 and c = 42 - 24 ie 18

-2 = c+2 subtract 2 from both sides so it'll be -4 =c
