Hello!

You can only combine numbers with the same variable

4r - 16r = -12r
5s + 3s = 8s

The answer is -12r + 8s

Hope this helps!

Hello, there!

We must combine like terms.

4r and -16r are like terms.

4r + (-16r) = -12r

5s and 3s are like terms.

5s + 3s = 8s

Our final answer is -12r + 8s

I hope I helped!

Let me know if you need anything else!

The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about

tatyana61 [14]

Answer:

$Sea\ of\ Galilee = -690ft$

Step-by-step explanation:

Given

$Lowest\ Elevation = 23ft$ below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

$Lowest\ Elevation = -23ft$

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

$Sea\ of\ Galilee = 30 * -23ft$

$Sea\ of\ Galilee = -690ft$

<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>

15. PLEASE HELP ME

Surface Area=7238in^2

We know

$\boxed{\sf Surface\:area=4\pi r^2}$

$\\ \sf\longmapsto 4\pi r^2=7238$

$\\ \sf\longmapsto 4\times \dfrac{22}{7}r^2=7238$

$\\ \sf\longmapsto r^2=\dfrac{7238\times 7}{88}$

$\\ \sf\longmapsto r^2=\dfrac{5066}{88}$

$\\ \sf\longmapsto r^2=575.75$

$\\ \sf\longmapsto r^2\approx576$

$\\ \sf\longmapsto r\approx\sqrt{576}$

$\\ \sf\longmapsto r\approx24in$

Travis wants to build a fence around his mother's rectangular garden. The length of the garden is 315 centimeters, and the width

Mariulka [41]

Answer: 12.1 meters

Step-by-step explanation:

This is a rectangular fence so it represents a rectangle.

Fencing the garden will require going around it therefore you are looking for the perimeter.

Perimeter of a rectangle = (2 * Length) + ( 2 * Width)

= (2 * 315) + ( 2 * 290)

= 1,210 cm

Convert to meters:

A meter is 100 centimeters

= 1,210 / 100

= 12.1 meters
