Match the terms to their definition. 1. additive identity 3 the reciprocal of a number; if x is a number other than zero, then 1/x is the multiplicative inverse; the product of a number and its multiplicative inverse is 1 2. multiplicative identity 2 the number 1 (for the real numbers) 3. multiplicative inverse 1 the number 0 (for the real numbers)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

1. 34

2. 268

3. x=14.4

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

add 8+12 to get a simplified answer of 12r-20
