Answer:
t = 11/4
Step-by-step explanation:
Step 1: Write out equation
4t - 2 = 9
Step 2: Add 2 on both sides
4t = 11
Step 3: Divide both sides by 4
t = 11/4
82 degrees and 98 degrees
First, find the original equation
180 = (x) + (x + 16)
Simplify: 180 = 2x + 16
Next, use the subtraction property of equality to subtract 16 from both sides
180 - 16 = 2x + 16 - 16
Simplify: 164 = 2x
Then, you can use the division property of equality to find the value of x
164/2 = 2x/2
Simplify: 82 = x
Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees
Given the definition of the absolute value function, there are two possibilities for the next step.
Rember that |x| = x when x is positive and |x| is - x when x is negative.
So, these are the two possibilities for |x - 2| = 4
1) When the content inside the absolute value is positive, you can state x - 2 = 4
2) When the content inside the absolute value is negative you can state x - 2 = - 4.
So, the answer is
x - 2 = 4 and x - 2 = - 4.
I found this list of choices for this question:
<span>a. x + 2 = −4
b. −x − 2 = 4
c. x + 2 = 4
d. x − 2 = −4
</span>
In that list , the only right is x - 2 = - 4, so choose it.
Answer: option d. x - 2 = - 4
Answer:
Answer is 7.8 and 7.9
Step-by-step explanation:
Cosine of angle F = adjacent side / hypotenuse
Cosine of angle F = 60/61 Option C
In image 2, we have to find out the adjacent side
adjacent side =√ 41² - 40² = √81 = 9
Cosine of angle X = 9/41
Option C
