Answer:

x = 5/4

Step-by-step explanation:

By combining like terms, you get 8x = 10.

Divide the 8 on both sides of the equation.

x = 10/8

This, however, can be simplified by dividing by 2. This ultimately gives us 5/4.

Answer:

x=5/4

Step-by-step explanation:

Hi there! I'd be happy to help you solve this equation!

To combine the equation 3x+5x=10's "like" terms, you simply add the 3 and 5, resulting in 8, being sure not to leave out the x.

Now we're left with 8x = 10.

Solve for x: Divide both sides of the equation by 8. You can use a calculator!8x/8 = 10/8

Hence, our answer is now x = 5/4.

I hope this helped you! Comment below if you think I've made a mistake or would like further explanation! <3

Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?

Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract $2\pi r^2$ from both sides of the equation:

$s=2\pi rh+2\pi r^2$

$s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2$

$s- 2\pi r^2=2\pi rh$

Now she needs to divide both sides of the equation by $2\pi r$ , then:

$h=\frac{s- 2\pi r^2}{2\pi r}$

Rewriting:

$h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}$

Simplifying, she should get:

$h=\frac{s}{2\pi r}-r$

This matches with the first option.

Two angels re supplementary. The larger angle is 48 degrees more than the 10 times the smaller angle. Find the measure of each a

evablogger [386]

Supplementary angles are two angles that add up to 180°.

STEP 1:
find the value of x

x= smaller angle
10x + 48= larger angle

Add the two angles above to equal 180.

x + (10x + 48)= 180
combine like terms

11x + 48= 180
subtract 48 from both sides

11x= 132
divide both sides by 11

x= 12° smaller angle

STEP 2:
find the value of the second angle

=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle

CHECK:
12° + 168°= 180°
180°= 180°

ANSWER: The smaller angle is 12° and the larger angle is 168°.

Hope this helps! :)

Qual son los pares de 48

lyudmila [28]

Answer:

Step-by-step explanation:

Es un proceso de dos pasos para crear todos los pares de factores de 48: Primero, enumeramos todos los factores de 48. Luego, combinamos todas las diferentes combinaciones de factores para obtener todos los pares de factores de 48.

Todas las diferentes combinaciones de pares de los factores de 48 anteriores son los pares de factores de 48. A continuación se muestra la lista de todos los pares de factores de 48. Como puede ver, todos los pares de factores de 48 equivalen a 48 cuando los multiplica

It is a two-step process to create all the Factor Pairs of 48: First, we list all the factors of 48. Then, we pair all the different combinations of factors to give you all the Factor Pairs of 48.

All the different pair combinations from the factors of 48 above are the Factor Pairs of 48. Below is the list of all the Factor Pairs of 48. As you can see, all Factor Pairs of 48 equal 48 when you multiply them together.
