Answer:
1. Combine the constant terms by adding 7 and –2.
4. Combine the like variable terms by adding the coefficients
5. 5 k and negative 3 k are like variable terms
6.The constants 7 and –2 are like terms.
7. The equivalent expression is 5 + 2 k + n.
Answer:
48°
Step-by-step explanation:
In triangle CYZ, angles Y and C are complementary, so ...
(5x +22) + (12x) = 90
17x +22 = 90
17x = 68
x = 4
The angle of interest is 12x° , so has measure
12·4° = 48°
