One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
Divide both sides
3x+y-6=0
move variable
6x=12-2y
divide
x=2-1/3y
solve
Final answer:
x=2
To answer that question, find the closest perfect squares on either side of 
. Those are the whole numbers falls between.
What is the closest perfect square less than 51?
What is the closest perfect square greater than 51?
Take the square root of both those numbers and you have your answer.
Answer:
t - 2 ≥ 7; t ≥ 9
Explanation:
“a number t” = t
“decreased by 2” = - 2
“Is at least 7” = ≥ 7
So, t - 2 ≥ 7
To solve for t - 2 ≥ 7, add 2 to both sides of the equation
t - 2 ≥ 7
t - 2 + 2 ≥ 7 + 2
t ≥ 9
So, t ≥ 9
Answer:
expository
Step-by-step explanation:
because being persuasive you have to be convincing, while being expository means like getting to the pont, literally.
Truth is, im stuck too, but anyway 50-50
