Time is 4 hrs., coffee is 0 cups. Point (4,0)
So A
Answer:
28
Step-by-step explanation:
Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:
3x+4 = 5x-6
3x+10 = 5x
10 = 2x
x = 5
Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:
(3*(5)+4)*2
=(15+4)*2
=19*2
=28
(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)
Therefore, the length of AC is 28.
Answer:
Hey!
Your answer is 44!
Step-by-step explanation:
Here's how...
x+(x+2)+(x+4)+(x+6)+(x+8)=200
5x+20=200 (minus 20 on both sides to get 5x by itself)
5x=180 (divide both sides by 5 to get just x)
x=36
5th number - x+8=36+8=44 (simple substitution and addition)

Answer: 21
Step-by-step explanation: hope this helps :)
Answer:
12 feet
Step-by-step explanation:
Given in the question,
horizontal distance from sister to rock wall = 5.5 feet
diagonal distance from sister to rock wall's peak = 13.42 feet
<h3>
To find the height </h3>
As we know this figure make a right angle triangle, so we will apply pythagorus theorem
hypotenuse² = height² + base²
13.42² = height² + 5.5²
13.42² - 5.5² = height²
149.85 = height²
height = √149.85
height = 12.24 feet
Approximate height of her rock wall to the nearest tenth = 12 feet
