X/62+89=92 !!!! plz quick

1 answer:

5 0

To solve an algebraic equation, we need to get x by itself. We can start to do that by multiplying each side of the equation by 62 (to remove the denominator of x).

x + 89(62) = 92 * 62

Simplify

x = 92 * 62 - 89 * 62

Now we can factor out 62

x = 62 (92 - 89)

Now we can simplify the parenthesis

x = 62 * 3

x = 186

Rationalise the denominator.

Let's see what to do buddy...

_________________________________

To do this, we have to multiply the face and denominator of the fraction by the denominator conjunction, which is :

$(5 -\sqrt{2})$

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

Reminder :

$(a + b)(a - b) = {a}^{2} - {b}^{2} \\$

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

$\frac{1}{ 5-\sqrt{2} } \times \frac{ 5+\sqrt{2} }{ 5 +\sqrt{2} } = \frac{1 \times ( 5 +\sqrt{2}) }{(5- \sqrt{2} )( 5 +\sqrt{2}) } = \\$

The other is in the photo.

And we're done.

Thanks for watching buddy good luck.

Find the volume of a cylinder with height 6.3 m and diameter 4 m. Use pi = 3.14

telo118 [61]

$volume \: of \: cylinder \: = \pi {r}^{2} h$
diameter = 4m
radius = 4/2
= 2m

volume = (3.14)(2^2)(6.3)
= 79.128m^3

A line is a undefined term because

SashulF [63]

The best answer I can think of is that a line doesn't have a point where it starts or stops, but instead goes on forever, unlike a ray which has a start or end point but not the other, and a line segment which has a start and stop point. Hope this helps!
