Add the two together. You get -3x-5x-y+y=6+10 which simplifies to -8x = 16 or x=-2

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486

Solve each proportion

mamaluj [8]

Hello.

In order to solve a proportion, you should cross-multiply:

$\displaystyle\frac{7}{x} =\frac{5}{9}$

Multiply 7 times 9 and 5 times x:

5x=63

Divide both sides by 5:

x= $\displaystyle\frac{63}{5}$

Now let's solve the second proportion.

Multiply 8p times 6 and 12 times 15:

48p=180

Divide both sides by 48:

p=3.75

I hope it helps.

Have an outstanding day.

The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greate

zhannawk [14.2K]

Answer:

Step-by-step explanation:

35 is exactly 152 but since its asking for greater then you're right it is 36.

But since it says '>' it means not equal to so it would be:

x > 35

x ≥ 36
