3*x=3x
3*-5=15
you just distribute the 3 to both values in the parenthesis.
so then we have
17=3x-15+8
simplify
17=3x-23
add 23 to both sides
40=3x
divide both sides by 3
x=13 1/3
The answer is 107

Answer:
B
Step-by-step explanation:
The scientific notation is symbol or the shorten way to rewrite the number that is too small or too large to write the full number. The scientific notation of a number has the form as the formula below:
<em>c x 10^n </em>
Based on this formula, it can be seen that answer C and D are not the correct answer.
Furthermore, in this formula, <em>c </em>can be any number ranging from 1 to 10 but not including 10 and <em>n </em>has to be an integer number.
So that in answer A, <em>c = 56 > 10 </em><em>is inappropriate.</em>
In answer B, <em>1< c = 5.6 < 10</em> and <em>n = 6 </em>
=> B is the correct answer

Answer:
<h3>x = 7</h3>
Step-by-step explanation:
2 angles are added to result in = 180°
therefore
180 = 97 - 3x + 69 + 5x
180 = 166 + 2x
2x = 180 - 166
2x = 14
x = 14 ÷ 2
<h3>x = 7 ✅</h3>
