The answer is cos70
the angles add up to 180, so 180 - 90 - 20 = 70 degrees.
Answer:
Step-by-step explanation:
<u>There are total cadies in the bag:</u>
<u>Probability of pulling a coffee candy is:</u>
So each 5th candy should be coffee candy
<u>Then you need to pull at least:</u>
<em><u>Note:</u></em>
<em><u>To ensure 3 coffee candies you would need to pull 25 - 2 = 23 candies</u></em>
0 is the y interception because that is where the line goes through on the graph

Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.
