Isolate the x. Subtract 20x from both sides, and add 15 to both sides
-5x (-20x) - 15 (+15) > 10 (+15) + 20x (-20x)
-5x - 20x > 10 + 15
Simplify. Combine like terms
-25x > 25
Isolate the x. Divide -25 from both sides. Note that when you are dividing by a negative number, flip the sign.
(-25x)/-25 > (25)/-25
x > 25/-25
x < -1
x < -1 is your answer
hope this helps
Step-by-step explanation:
Let us consider the task to find the angle between vectors ES and EJ (the first letters are taken to name the vectors).
\overrightarrow{ES} = (4;4) - (4; -3) = \overrightarrow{(0; 7)}
ES
=(4;4)−(4;−3)=
(0;7)
\overrightarrow{EJ} = (-5; -4) - (4; -3) = \overrightarrow{(-9; -1)}
EJ
=(−5;−4)−(4;−3)=
(−9;−1)
cos \alpha=\frac{\overrightarrow{ES}*\overrightarrow{EJ}}{|\overrightarrow{EJ}|*|\overrightarrow{ES}|}cosα=

cos(a) = (0*(-9)+7*(-1)) / (7*9.055) = -0.11043;
a = 96,34°
Solution: 96 degrees.
Answer: Value of k must be 40.
Step-by-step explanation:
Since we have given that
28 is 12 less than k
1) 12 less than k means
As we use "Subtraction" for less than purpose.
2) For "is" we would use "Equality":
So, our final equation becomes
Hence, Value of k must be 40.
