What is the simplest form of 2/10?

1 answer:

4 0

<span>To get to the simplest form you have to divide numerator and denominator by numbers they can both be divided by, until you get to a fraction where you can't divide both anymore getting an integer as a result.
Here you can only divide by 2 and you get 1/5. That's the simplest form</span>, if you kept dividing you'd get decimals, but the simplest form must be integers.

Solve for x. 9^x+15=3^7x

Art [367]

The solution is x = 6

Step-by-step explanation:

Let us revise some rules of the exponents

If $a^{n}=a^{m}$ , then n = m
$(a^{n})^{m}=a^{nm}$

∵ $9^{(x+15)}=3^{7x}$

∵ 9 = 3 × 3

∴ 9 = 3²

- Substitute 9 by 3² in the equation above

∴ $(3^{2})^{(x+15)}=3^{7x}$

- Use the second rule above for the left hand side

∵ $(3^{2})^{(x+15)}=3^{2(x+15)}$

∴ $(3^{2})^{(x+15)}=3^{2x+30}$

∴ $3^{2x+30}=3^{7x}$

- By using the first rule above

∴ 2x + 30 = 7x

- Subtract 2x from both sides

∴ 30 = 5x

- Divide both sides by 5

∴ 6 = x

The solution is x = 6

Draw a diagram in which segment AB intersects segment CD equals segment CB

Contact [7]

The <u>correct diagram</u> is attached.

Explanation:

Using technology (such as Geogebra), first construct a line segment. Name the endpoints C and D.

Construct the perpendicular bisector of this segment. Label the intersection point with CD as B, and create another point A above it.

Measure the distance from C to B and from B to D. They will be the same.

Measure the distance from A to B. If it is not the same as that from C to B, slide A along line AB until the distance is the same.

Using a compass and straightedge:

First construct segment CD, being sure to label the endpoints.

Set your compass a little more than halfway from C to D. With your compass set on C, draw an arc above segment CD.

With your compass set on D (the same distance as before) draw an arc above segment CD to intersect your first arc. Mark this intersection point as E.

Connect E to CD using a straightedge; mark the intersection point as B.

Set your compass the distance from C to B. With your compass on B, mark an arc on EB. Mark this intersection point as A.

AB will be the same distance as CB and BD.
