-6 + x = -3
x = -3 + 6
x = 3 <==
-x = 3 - 4x + 6
-x + 4x = 3 + 6
3x = 9
x = 9/3
x = 3 <==
Answer:
The green one
Step-by-step explanation:
In an obtuse triangle, one of the angles is greater than 90 degrees.
<h2>
Answer:</h2><h2>(i) Total expenses = $ 300</h2><h2>(ii) Net income(savings) = $ 0</h2>
Step-by-step explanation:
Total income earned by Sam = $ 300
(i) Expense calculation,
Clothes expense = 30 % = 30 % (300) = $ 90
Food and snacks expense = 23 % = 23 % (300) = $ 69
Cell phone expense = 14% = 14% (300) = $ 42
Transportation expense = 10% = 10% (300) = $ 30
Gym expense = 10% = $ 30
Movies expense = 8% = 8% (300) = $ 24
Apps expense = 5% = 5% (300) = $ 15
Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300
(ii) Sam's net income is the profir earned after his expense.
Net income = 300 - 300 = $ 0
To find y you must recognize that 141+3y=180 . You know this since half of a circle is 180, and a line is basically half a circle if you arc from end point to end point.
You can then subtract 141 from both sides,
3y = 39
Then divide both sides by 3,
y=13
You would want to use 39° for 3y° since 3·13= 39.
A triangle can only contain 180°, so you would add 68 and 39 together and then subtract this from 180 to give you x.
68 + 39 + x = 180
107 + x = 180
x = 73
