Answer:
x = 9º
∠B = 40º
Step-by-step explanation:
5x-5º = 3x+13º
<em>[add 5 to both sides]</em>
5x = 3x+18º
<em>[subtract 3x from both sides]</em>
2x = 18º
<em>[divide each side by 2]</em>
x = 9º

3x+13º = 3(9º)+13º=27º+13º = 40º
30:6 is an equivalent ratio. Anymore and you would have a decimal.
Answer:
A- 16 songs a day
B- 32 songs in the weekend
Step-by-step explanation:
A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying 5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day
B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32
It can be written as √64·√x¹⁶ = 8x⁸, so answer B.
