Identify in the given expressions, terms which are not constants. Give their numerical coefficients. (i) 5x - 3 (ii) 11-2y² (iii) 2x - 1 (iv) 4x²y + 3xy²-5 with steps

Constants: The terms which are free from variables.  

Numerical coefficient: Number multiplied with a variable.  

(i)    Constant = -3  

Term which is not constant = 5x  

Numerical coefficient = 5  

(ii) 5x-3  

Constant = 11  

Term which is not constant =  

Numerical coefficient = -2  

(iii) 11-2y squared  

Constant = -1

Term which is not constant = 2x  

Numerical coefficient = 2  

Therefore, the terms which are not constants are 5x,-2y squared,2x   respectively and their numerical coefficients are 5, -2, 2 respectively.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
