Answer:

x = 4 - 5/2 y

Step-by-step explanation:

2x + 5y = 8.

Subtract 5x from each side

2x + 5y -5y = 8-5y

2x = 8 -5y

Divide each side by 2

2x/2 = (8-5y)/2

x = 4 - 5/2 y

Answer:

x=\frac{-5y}{2}+4

Step-by-step explanation:

Hi there!

We're given the equation 2x+5y=8 and we want to solve it for x

as we don't know the value of y, x won't actually be a number (it'll be an expression instead). However, we will solve this as if it was a regular equation by isolating x onto one side

here's the given equation

2x+5y=8

start by subtracting 5y from both sides

2x=-5y+8

divide both sides by 2

x=\frac{-5y}{2}+4

Hope this helps!

What is the answer (6√2)(-3√5)
alexgriva [62]

Solution:

- 18 \sqrt{10}

<h3>Step-by-step explanation:</h3>

<h3>1. Apply rule : a(-b) = -ab</h3>

<h3> </h3>

=  - 6 \sqrt{2}   \:  \: • \:  \: 3 \sqrt{5}

2. Apply radical rule : \sqrt{a}  \sqrt{b}  =  \sqrt{ab} , a \geqslant 0, b

=  6 \sqrt{2 \: • \: 5}  \: • \: 3

<h3>3.Multiply the numbers : 2 • 5 = 10</h3>

=6 \sqrt{10} •3

<h3>4.Multiply the numbers : - 6 • 3= - 18</h3>

=  - 18 \sqrt{10}

A cylinder has a surface area of 5652 square millimeters. If the diameter of the cylinder is 30 millimeters, what is the height?
o-na [289]
The formula for the surface area of a cylinder is:

\sf A=2\pi rh+2\pi r^2

Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):

\sf 5652\approx 2(3.14)(15)h+2(3.14)(15)^2

Simplify:

\sf 5652\approx 94.2h+1413

Subtract 1413 to both sides:

\sf 4239\approx 94.2h

Divide 94.2 to both sides:

\boxed{\sf h\approx 45~mm}

So the height is approximately 45 millimeters.
