Can someone help me with this ONE question? Write an equation.. and solve for X

matrenka [14]

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.

the tens digit of a two digit number is twice the units digit. The sum of the digits is twelve. Find the original number.

KatRina [158]

X - tens digit
y - units digit

$x=2y\\
x+y=12\\\\
2y+y=12\\
3y=12\\
y=4\\\\
x=2\cdot4\\
x=8\\\\
10\cdot8+4=\boxed{84}

Evaluate the indefinite integral. (Use C for the constant of integration.) ex 5 ex dx.

melisa1 [442]

Answer:

$5 e^{x} +C$

where C is constant of integration

Step-by-step explanation:

Explanation:-

Given f(x) = 5 eˣ

Now integrating with respective to 'x' , we get

I = $\int\limits {5 e^{x} } \, d x$

By using integration formula

$\int\limits { e^{x} } \, d x = e^{x} +C$

$I = \int\limits {5 e^{x} } \, d x = 5 e^{x} +C$

where C is constant of integration

Does anyone know this?

vladimir2022 [97]

Answer:

x = 4

Step-by-step explanation:

By BPT

$\frac{10 - x}{x} = \frac{3}{2} \\ \\ 2(10 - x) = 3x \\ \\ 20 - 2x = 3x \\ \\ 20 = 2x + 3x \\ \\ 20 = 5x \\ \\ x = \frac{20}{5} \\ \\ x = 4$
