That 10cm does not mean point C is 10cm. It means the line AB is 10 cm in total.
And since point C is the midpoint, which means that point C cuts the line AB in half, that makes AC = 5cm

I don't understand how to find the values of X and Y. Can anyone explain?
Answer:
y=30
x=29
Step-by-step explanation:
2y=180-120
2y=60
y=30
4x+4=120
4x=116
x=29
3[-x + (2 x + 1)] = X – 1
Your question has been heard loud and clear.
3[-x + (2 x + 1)] = X – 1
= 3[-x+2x+1]= x-1
= 3 [ x+1] = x-1
= 3x+ 3 = x-1
3x-x = -3-1
2x= -4
so , x = -4/2 = -2
Therefore , x = -2
Thank you
Answer:
3x+3=x-1
3x-x=-1-3
2x=-4
x=-2
20. The temperature of a pot of water is 62*F. The temperature increases
by 20*F per minute when being heated. Write an equation to represent
the linear relationship. *
Given :
The temperature of a pot of water is 62 F .
The temperature increases by 20 F per minute when being heated .
To Find :
Write an equation to represent the linear relationship.
Solution :
Here , the temperature is increasing directly with the time .
Therefore , it is a linear equation .
Let temperature varies with as :
T = at+b .... equation 1 .
( Here , a and b are constants )
Now , at t= 0 min .
[tex]T = 62 =a\times 0 + b[/tex]
[tex]b=62[/tex]
Now , after 1 min temperature will be , T = 62 +20 =82 F
[tex]T = 82 = a\times 1+62\\a=20[/tex]
Putting value of a ans b in equation 1 , we get :
[tex]T=20t+62\ F[/tex]
Hence , this is the required relation .
Robert invested $25,000 in an account that pays 4.5% interest compounded weekly. After 3 years,
what is the balance of his account?
Answer:
28,375 dollars
Step-by-step explanation:

The formula x + y = 180 can be used to find the degrees of supplementary angles, where x is the smaller angle. Find the domain and range of this solution
Answer:
Domain : 0° < x <90°
Range: 90° < y < 180°.
Step-by-step explanation:
When we have a function:
f(x) = y
the domain is the set of the possible values of x, and the range is the set of the possible values of y.
In this case we have:
x + y = 180°
such that x < y
Let's analyze the possible values of x.
The smallest possible value of x must be larger than 0°, as we are workin with suplementary angles.
Knowing this, we can find the maximum value for y:
0° + y = 180°
y = 180° is the maximum of the range.
Then we have:
0° < x
y < 180°
To find the other extreme, we can use the other relation:
x < y.
Then, we can impose that x = y (this value will not be either in the range nor the domain)
if x = y then:
x + y = x + x = 180
2*x = 180
x = 90°
This will be the maximum of the domain and the minimum of the range.
Then we have that the domain is:
0° < x <90°
And the range is:
90° < y < 180°.
what is the slope of the line Y equals 3
y = 3 is written in slope-intercept form (y = mx + b).
The only variable we are given in this equation is "b" which is "3".
We don't have a slope variable at all which means the slope is 0 or undefined.
The y-intercept is 3.
Best of Luck!

Point L is on line segment KM. Given LM = 3x + 3, KM = 5x + 4, and
KL = 5x + 1, determine the numerical length of KM.
Answer:
[tex]KM = 4[/tex]
Step-by-step explanation:
Given
[tex]LM = 3x + 3[/tex]
[tex]KM = 5x + 4[/tex]
[tex]KL = 5x + 1[/tex]
Required
Determine KM
The relationship between the given parameters is:

Answer:
4. 770 people
5. 16 min
6. 10.8 laps
Step-by-step explanation:
4. 330 people = x
3 hours 7 hours
just cross multiply:
3x = 330(7)
x = 2310 / 3
x = 770 people
5. 15 laps = 30 laps
8 x
just cross multiply:
15x = 30(8)
x = 240 / 15
x = 16 mins
6. 18 laps = x
10 6
just cross multiply:
10x = 18(6)
x = 108 / 10
x = 10.8 laps
John has a debit card with $100.00 on it. He uses his debit card to buy his lunch everyday. His lunch costs $4.50 per day. How many lunches can John buy?
Answer:
He can buy 22 lunches.
Step-by-step explanation:
To find how many he can buy if he had $100, we must divide the cost of one lunch to the amount of money he has.
(Round to the nearest whole number to get the exact amount of lunches that he can buy.)
1 lunch = $4.50
So:
=$100 ÷ $4.50 = 22.222....
=22.222.... = 22
Hope this helps! I'm sorry if it's wrong.
explain why 2a+3b=5ab
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab

kaitlin bought some books. she spent a total of 45 after a discount of $6 off her total purchase. Each book cost $3. How many books did she buy
Answer:
17
Step-by-step explanation:
Answer: She bought 17 books
Step-by-step explanation:
Add $6 to the amount that she paid to find out how much money she would have paid.
45 + 6 = 51 so she would have paid $51
Now divide 51 by 3 to find out how many books she bought.
51 / 3 = 17
So because of the discount, she paid $45 for 17 books.
Point P is the interior of LaTeX: \angle OZQ.\: ∠ O Z Q . If LaTeX: m\:\angle\:OZQ\: m ∠ O Z Q = 125 and LaTeX: m\angle OZP\: m ∠ O Z P =62, what is LaTeX: m\angle PZQ m ∠ P Z Q ?
Answer:
63°Step-by-step explanation:
If Point P is the interior of ∠OZQ, then ∠ O Z P +∠ P Z Q = ∠ O Z Q
Given O Z Q = 125 and m ∠ O Z P =62, to get ∠ P Z Q, substitute the given angles into the formula above as shown;
∠ O Z P +∠ P Z Q = ∠ O Z Q
62 +∠ P Z Q = 125
subtract 62 from both sides
62 +∠ P Z Q - 62= 125 - 62
∠ P Z Q = 63°
Hence the angle ∠ P Z Q is 63°

Find the point-slope equation for the line that passes through the points (30,2) and (15,-28) use the first point in your equation
Answer:
y=2x-58
Explanation:
In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)
This gives us:
y=2x + c
Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:
2=2(30) + c
2=60+c
2-60=c
-58=c
So now we know that our C (constant) is - 58.
Hence our point-slope formula is:
y=2x-58
Which you can test with the other point:
-28=2(15) - 58
Hope this helped!

Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to the ground? What does the integer 0 represent in this situation? The integer represents Xavier’s climb down. The integer 0 represents .
Answer:
The answer is "-9 feet and Ground-level".
Step-by-step explanation:
Given value:
total length or distance from apple tree = 9 feets
In the calculation of the distance between both the ground and the tree will be the same.
If he gets higher 9 feet, he will go back to the ground 9 feet, in this case, the represents ground value is equal to 0.
In the calculation of absolute values it value is opposite but the same.
