Answer:

Step-by-step explanation:

3x+4=5x-10

First, you have to combine your variables. By doing this you subtract 3x from both sides of the equation.

3x+4=5x-10

-3x -3x

4=2x-10

Next, you have to combine your whole numbers. In order to do so, you can subtract 2x and 4 from both sides so it would look like this:

4=2x-10

-2x -2x

-2x+4=10

-4 -4-

2x=-4-10

After that, you simplify -4-10, which is -14. Your equation should look like this:

-2x=-14

Finally, you need to isolate x. In order to do that, you need to divide -2 from both sides since you are multiplying -2 and x with the expression -2x.

-2x=-14

-2 -2

Your final answer is: x=7

OAA', OBB', and OCC' are straight lines. Triangle ABC is mapped onto Triangle A'B'C' by an enlargement with center O. What is th

bazaltina [42]

Answer:

(D) 2

Step-by-step explanation:

The scale factor of the enlargement of ΔABC to ΔA'B'C' is given by the ratio of the length of the corresponding sides of ΔA'B'C' and ΔABC

Therefore, we have;

$The \ scale \ factor = \dfrac{Length \ of \overline {B'C'}}{Length \ of \overline {BC}} = \dfrac{Length \ of \overline {A'C'}}{Length \ of \overline {AC}} = \dfrac{Length \ of \overline {A'B'}}{Length \ of \overline {AB}}$

$\dfrac{Length \ of \overline {B'C'}}{Length \ of \overline {BC}} = \dfrac{2 \ units}{1 \ unit} = 2$

$\dfrac{Length \ of \overline {A'C'}}{Length \ of \overline {AC}} = \dfrac{4 \ units}{2 \ units} = 2$

$\dfrac{Length \ of \overline {A'B'}}{Length \ of \overline {AB}} = \dfrac{2 \cdot \sqrt{5} \ units}{\sqrt{5} \ units} = 2$

Therefore, the scale factor = 2

What is the central difference between line functions and staff functions?

Tasya [4]

Staff and line are names given to different types of functions in organizations. A "line function" is one that directly advances an organization in its core work. This always includes production and sales, and sometimes also marketing.

The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula

Semmy [17]

Answer:

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

$V=\frac{4}{3} \pi r^{3}$

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

$V=\frac{4}{3} \pi r^{3}$ ......Given

$3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}$

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r
