What is the solution of the equation w – 8 =5? Show your work

Marta_Voda [28]

Answer:

Step-by-step explanation:

first one: w-8 =5

reverse it- 8+5= 13 so 13-8= 5

second one: 5x-2

2x-2+3x << group together the x's

2x+3x=5x and you'll end up with 5x-2

last one: r/5=-9

again, reverse it- -9 x 5 = -45

a negative times a positive = a negative

Cos²45+Sin²60 + sin^2 30

denpristay [2]

Step-by-step explanation:

${ \cos}^{2} 45 \degree + { \sin}^{2} 60 + { \sin}^{2} 30 \degree \\ = \bigg( \frac{1}{ \sqrt{2} } \bigg)^{2} + \bigg( \frac{ \sqrt{3} }{ 2} \bigg)^{2} + \bigg( \frac{1}{2} \bigg)^{2} \\ \\ = \frac{1}{2} + \frac{3}{4} + \frac{1}{4} \\ \\ = \frac{2}{4} + \frac{3}{4} + \frac{1}{4} \\ \\ = \frac{2 + 3 + 1}{4} \\ \\ = \frac{6}{4} \\ \\ = \frac{3}{2} \\ \\ = 1 \frac{1}{2} \\$
