Find the value  If a=7 ,b=4, c=3,x=5 and y=2 find the value of (i) 5bc      5 x b x c     = 5 x 4 x 3     = 60 (ii) 3a +4x    = 3 x a + 4 x x   = 3 x 7 + 4 x 5  = 21 + 20  = 41 (iii) 4c - 3y       4 x c - 3 x y =   4 x 3 - 3 x 2 =  12 - 6 =  6. (iv) 2a -3b + 4y = 2 x a - 3 x b + 4 x y = 2 x 7 - 3 x 4 + 4 x 2 = 14 - 12 + 8 = 2 + 8 = 10.

Express using symbols 1. y subtracted from x x-y 2.5 multiplied by k 5 k 3.n added to m m + n 4. a divided by 3 a/3 5. p multiplied by r pr 6. x divided by a x/a 7.Thee sum of a,m and x a+ x+m 8. The product of a, b, x a b x 9 The difference between 8 and 5 is 3 8-5=3 10.The sum of 8 and 3 is equal to the sum of 5 and 6 8 + 3 = 5 + 6
