Answer:
y=4, n=16
Step-by-step explanation:
4y+3=19
4y=19-3
4y=16
y=16/4
y=4
1/2n-3=5
1/2n=5+3
1/2n=8
n=8÷1/2
n=8/1×2/1
n=16

Answer:
Variable x in first equationStep-by-step explanation:
Given system
x = 5y - 1x + 2y = 13Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see variable x is isolated in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
Answer:
x
Step-by-step explanation:
x=5y-1--(1)The x variable is isolated here as it's solo on left side
Solve the equations
x+2y=13x=-2y+13--(2)Equate
5y-1=-2y+137y=14y=2x=10-1=9
Write the equation of a line that is parallel to y = -2/3 x + 1 and passes through the point (-6,-1).

Can someone help me i will give extra points
For the top part, both equations are vertical angles, so both equations will equal the same angle.
(4 + 23x) = (24x)
4 + 23x = 24x
4 = 24x - 23x
4 = x
Plug in x = 4 into both equations.
4 + 23(4) = 24(4)
4 + 92 = 96
96 = 96
Since x = 4 is a solution for both equations, the angle that is equal to both is 96 degrees.
Answer: 96 degrees is the angle--------------------------------------------------------------------------------------------------------------
For the bottom part, both equations lie on the same straight line, so adding both equations together will equal 180 degrees.
(x + 120) + (x + 80) = 180
x + 120 + x + 80 = 180
2x + 200 = 180
2x = 180 - 200
2x = -20 (don't worry about having a negative solution)
x = -10
Plug in x = -10 into both equations.
(-10) + 120 + (-10) + 80 = 180
110 + 70 = 180
180 = 180
Since x = -10 is a solution for both equations, the angle for equation (x + 120) is 110 degrees and angle for equation (x + 80) is 70 degrees.
Answer: Since the question asked to find a measure of the angle indicated in bold, the angle measure is 70 degrees.Anna likes to skate at a candy store that is due south of her school and due west of her favorite skate park. If the candy store is 8 miles from her school and the straight-line distance between the school and the skate park is 10 miles, how far is the candy store from the skate park?
Answer:
6 miles
Step-by-step explanation:
Given that the candy store that is due south of her school and due west of her favorite skate park, the distance between the the school and the skate park when considered with the distance between the candy store and her school and that between the candy store and her favorite skate park gives us a right angled triangle.
The distance between the school and the skate park is the longest side (hypotenuse of the triangle so formed). As such, using Pythagoras theorem
10^2 = 8^2 + x^2 where x is the distance between the Candy store and the skate park
100 = 64 + x^2
100 - 64 = x^2
36 = x^2
6^2 = x^2
x = 6
The distance between the candy store and the skate park is 6 miles
1. Could you use an inscribed prism to derive the volume of a hemisphere? Why or why not? Are there any other ways you could approximate a hemisphere, and what problems would you encounter in finding its volume?
2.Could you use a circumscribed regular n-gon as the base of a pyramid to derive the formula for the volume of a cone? Explain.
We can always get the volume of the figure whenever we get enough data to recreate that considered figure, because it provides us with necessary measurements needed for finding the volume.
When can we find the volume of a considered figure?For finding volume of the considered figure, we somehow needs measurement of its correct dimensions by which we would be able to recreate the figure. By any means, if we could get enough measurement, then we'd be able to characterize the figure, and thus, get its volume.
Case 1. Could you use an inscribed prism to derive the volume of a hemisphere? Why or why not? Are there any other ways you could approximate a hemisphere, and what problems would you encounter in finding its volume?
Yes, if the prism fits perfectly, and we know about the prism, then it would tell us about the radius of the hemisphere. For example, we can fit a cubic prism inside it, and diagonal of that cube's base will give diameter of that hemisphere.
Case 2.Could you use a circumscribed regular n-gon as the base of a pyramid to derive the formula for the volume of a cone?
Yes, because the the base of the pyramid can give the details about radius of the cone's base, and due to the n-gon being regular and circumscribed, the height of the cone would be same as that of the height of that n-gon.
Thus, we can always get the volume of the figure whenever we get enough data to recreate that considered figure, because it provides us with necessary measurements needed for finding the volume.

Hometown Gym charges a $200 membership fee and $45 per month. Local Gym charges a $50 membership fee and $55 per month. Write an equation to represent the situation. After how many months will the total amount of money paid to both gyms be the same?
Answer:
=> membership fee = $50
=> monthly fee = $55
=> First month = 105$
=> 50 + 55(x)
=> 50 + 55 (15)
=> 50 + 825

Looking at the letter arrangement in the problem B is similar to W
Set those equal to each other and solve.
X + 24 = 2x -2
Subtract x from both sides:
24 = x -2
Add 2 to both sides:
X = 26
Now replace x in the equation for B
2x -2 = 2(26)-2 = 52-2 = 50
B = 50 degrees

Fine the missing length indicated.
Answer:
144
Step-by-step explanation:
the height is sqrt(65^2-25^2) = 60
the length of the unknow side of the largest triangle is sqrt((25+x)^2-65^2)
or also sqrt(x^2+60^2)
set them to equal
sqrt((25+x)^2-65^2) = sqrt(x^2+60^2)
==> x = 144

Answer:
4. 28 sq. inch
Step-by-step explanation:

Area of the triangle = 1/2 x b x h
= 1/2 x 2 x 6
= 6
Total surface area = Area of square + 4 x area of triangle
= 4 + 4 x 6

Timberly spent 3 4/5 hours in Misty spent 2 1/10 hours at gymnastics practice over the weekend. How many more hours did Timberly spend than Misty at the gymnastics practice?
Answer:
Step-by-step explanation:
The common denominator of these 2 fractions is 10.
Turn the mixed number 3 4/5 into an improper fraction which would be
19/5.
Then multiply the numerator and denominator with 2 to get the denominator to be 10.
19/5 x 2 = 38/10
Now turn 2 1/10 into an improper fraction= 21/10
Now subtract...
38/10 - 21/10 = 17/10
So Timberly spent 17/10 or 1 7/10 more hours then Misty at the gymnastics practice
