Answer:
y = 0
Step-by-step explanation:
Let's use the addition method.
2x + y - 10 = 0
x - y - 5 = 0
Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.
2x + y - 10 = 0
(+) -2x + 2y + 10 = 0
--------------------------------
3y = 0
Divide both sides by 3.
y = 0
Answer: y = 0

Cylinder radius is 2 cm height is 10cm what is the surface area
Answers
Given:
Radius of a cylinder = 2 cm
Height of the cylinder = 10 cm
To find:
The surface area of the cylinder.
Solution:
The total surface area of the cylinder is:
[tex]A=2\pi rh+2\pi r^2[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2[/tex] and [tex]h=10[/tex] in the above formula, we get
[tex]A=2\pi (2)(10)+2\pi (2)^2[/tex]
[tex]A=40\pi +2\pi (4)[/tex]
[tex]A=40\pi +8\pi [/tex]
[tex]A=48\pi [/tex]
Therefore, the surface area of the cylinder is [tex]48\pi [/tex] square cm and its approximate value is 150.8 square cm.

The value of Kelsey's car will depreciate (decrease) by a rate of 15% each year. She wants to write an exponential equation to find out what it will be worth in 6 years. What is the multiplier for this situation?
Answers
So if you multiply 15 by 6 you get 90 and the 6 is from every years she has saved. So if you take any number 95000 and 15 percent of 95000 is 14250 so try breaking it down and divide as much as you can but not to much and slowly at a time and then when you get that try to get close to 9500 as much as you can cause 90 percent of 95000 is 9500.

A cube that is used as a table is 2ft on each side. how many square feet will be painted if all sides are painted
A. 24ft²
B. 48ft²
C. 36ft²
Answers
Answer:
a = 24 ft²
Step-by-step explanation:
Area of 1 side
a = 2 * 2
a = 4 ft²
Cubes have 6 sides
a = 6 * 4
a = 24 ft²
Answer:
A. 24 ft²
Step-by-step explanation:
The faces of a cube are squares. We know that the squares have a side length of 2 ft. Therefore, the area of a square will be 4 ft². There are 6 faces/squares on a cube, so we take the 4 ft² and multiply it by 6. This gives us 24 ft².

Surface Area
Answers
Answer:
107 in ²
Step-by-step explanation:
Surface area of the triangular prism = bh + L(s1 + s2 + s3)
Where,
b = 2 in.
h = 8 in.
s1 = 8.2 in.
s2 = 2 in.
s3 = 8 in.
L = 5 in.
Substitute
Surface area = 2 × 8 + 5(8.2 + 2 + 8)
Surface area = 16 + 5(18.2)
Surfaces area = 16 + 91
Surface area = 107 in ²

the price of a ring was increased by 30% to £325 what was the price before the increase
Answers
Answer is : Price before increase is £250
Explaination:
Let the Original price of a ring = x
Increase price( g) = 30%
New price(n) = £325
x = ( 100*n)/ (100+g)
x= (100*325)/(100+30)
x= (200*325)/130
x= 250
Therefore price before increase is £250
Another method:
Given that after 30% increases,
the cost of the ring is £325 so we can assume that 130% (100+30) is £325.
Now, we have to form an expression in term of x where x represents the original cost :
130/100*x=325
Solving x
x= 250
So the original price or price before the increase is £250

Answer:
the third side is 4.
Step-by-step explanation:
Using Pythagorean theorem of a^2 + b^2 = c^2 for right triangles, substitute
the numbers to show ([tex]\sqrt{65})^{2}[/tex] + [tex]b^{2}[/tex] = [tex]9^{2}[/tex] and solve for b. The square root and square cancel each other out, so you get 65 + [tex]b^{2}[/tex] = 81.
Subtract 65 from both sides to get [tex]b^{2}[/tex] = 16.
Then take the square root of both sides to get b = [tex]\sqrt{16}[/tex] which equals 4.
