Step-by-step explanation:
[tex] \frac{1}{3 } - \frac{2y}{9} = 19 \\ \frac{3 - 2y}{9} = \frac{171}{9} \\ 3 - 2y = 171 \\ 2y = 3 - 171 \\ 2y = - 168 \\ y = - 168 \div 2 \\ y = - 84[/tex]
Answer: y = − 84
Step-by-step explanation:
Simplify 5(3y−1)−3(2y)
9y=24
divide by each term by 9
y=-84
-x - 163 = 12x + 84
Answer:
X = -19
Step-by-step explanation:
Add x to both sides to get rid of -x
-163 = 13x + 84
subtract 84 from both sides
-247 = 13x
divide by 13
x = -19

David buys 2 DVDs and 2 CDs in a shop and in total they cost £18.
Ellie buys 3 DVDs and 2 CDs in the same shop and they cost £22.
Form two equations and solve to find the cost of each DVD and each CD.
Answer: Down below
Step-by-step explanation:
Let x be the cost for the DVD's
Let y be the cost of the CD's
Equations :
2x + 2y = 18 OR y = (18 - 2x)/2
3x + 2y = 22
Substitution :
3x + 2[(18 - 2)/2] = 22
3x + 2(16/2) = 22
3x + 2(8) = 22
3x + 16 = 22
3x = 22 - 16
3x = 6
x = 6/3
x = 2
that's just the cost of the DVD though. now to find the CD's cost
Cost of CD's :
y = (18 - 2x)/2
y = [18 - 2(2)]/2
y = (18 - 4)/2
y = 14/2
y = 7
therefore 1 CD costs 7 pounds and 1 DVD costs 2 pounds

What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
A.
a) The height of the cylinder is given as 11 in and the radius is 6 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 6^2 x 11
= 1244.07cubics in
b) The height of the cylinder is given as 30 in and the radius is 24 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 24^2 x 30
= 54286.72 cubics in
c) The height of the cylinder is given as 21 in.
The radius of the base of the cylinder is given as 19 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 19^2 x 21
= 23816.41 cubics in
B.
d) The height of the cylinder is 9ft the radius is 3 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 3^2 x 9
= 254.47 cubics ft
e) The height of the cylinder is 8 ft the radius is 13 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 13^2 x 8
= 4247.43 cubics ft
f) The height of the cylinder is 27 ft the radius is 16 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 16^2 x 27
= 21714.69 cubics ft
g) The height of the cylinder is 15 ft the radius is 10 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 10^2 x 15
= 4712.39 cubics ft

there are currently 260 people in archery clubs across the city, and this number is increasing by 11% per year. Enter an equation that can be used to find the number of people, y, in archery clubs across the city after 8 years.
Given :
There are currently 260 people in archery clubs across the city, and this number is increasing by 11% per year.
To Find :
An equation that can be used to find the number of people, y, in archery clubs across the city after 8 years.
Solution :
Increase in people after 1 years :
[tex]P = 260 + 260\times 0.11\\\\P = 260( 1 + 0.11)\\\\P = 260\times 1.11[/tex]
After 2 years :
[tex]P = 260\times 1.11 + 260\times 1.11\times 0.11\\\\P = 260\times 1.11 ( 1 + 0.11)\\\\P = 260\times 1.11^2[/tex]
Therefore, after 8 years the expression of population is :
[tex]P = 260\times 1.11^8[/tex]
Hence, this is the required solution.

Solve for x
9x - 7 = 4x + 13
i need help with this i’m so confused in this topic
Answer: x=4
Step-by-step explanation:
First, you need to take both of the x to one side of the equation. To do that, subtract 4x from both sides of the equation. you will get 9x-7-4x=4x+13-4x. The 4xs on the right hand side of the equation will cancel out. So you will be left with an equation that looks like this: 9x-7-4x=13. Now, on the left hand side of the equation you can rearrange the numbers to look like this. 9x-4x-7=13. Do 9x-4x to get 5x and then add back your -7 and the =13. Now, your equation will look like this. 5x-7=13. Now, you need to get rid of the 7 on the left hand side of the equation in order to isolate the variable (which is x here). The easiest way to do this would be to add 7 to both sides (in order to keep the equation balanced, whatever you do on one side of the equation has to also be done on the other side.) of the equation so the +7 and -7 could cancel each other out. You would have 5x-7+7=13+7. Now, cancel out the 7s on the left hand side of the equation. You would be left with 5x=13+7. Add the 13 and the 7 on the right hand side of the equation to get 20. You would now have the equation 5x=20. Finally, you need to isolate the x, right? To do that, just divide both sides of the equation by 5. you would get 5x/5=20/5. And your final answer after simplifying should be x=4. Hope this helps!

Step 3: create and solve an equation to find the missing or angle.
At a point 30 feet from the base of a tree, the angle formed with the ground looking to
the top measures 53. Find, to the nearest foot, the height of the tree.
Can someone help me?
Answer:
40 feet to the nearest foot.
Step-by-step explanation:
The tree , the distance from the base of the tree on the ground (30 ft) and the distance from this point to the top of the tree form a right triangle.
So if the height of the tree is h:
tan 53 = h / 30
h = 30 tan53
h = 39.81 feet.

what is the value of -6-(x+3)y when x = -5 and y = 2????
Answer:
-2
Step-by-step explanation:
Answer: -2
Step-by-step explanation:
Substitute -5 for x and 2 for y in the expression, which gives -6 minus the quantity -5+3, all divided by 2.
Then, use the order of operations to simplify the numerator of the expression. Finally, simplify the fraction, which gives -2. So, when x equals -5 and y equals 2, the expression is equal to -2.
