Answer:
x = 
Step-by-step explanation:
Using the rule of exponents
= 
Note that 8 = 2³ and 2 =
, then
=
, that is
= 
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x = 
Answer:
$695
Step-by-step explanation:
So if each camera costs $6.95 snd he wants 100 you would multiply by 100. And that would be 6.95×100=695 and a good trick I've learnt is that you just move the numbers 1 column to the left for each zero so if it was 10 you'd move all the numbers 1 column to the left. It is abit hard to explain but you're answer is there just thought that'd help in future.
4/5 a mile
2/10 time 10=20/100
20/100+ 60/100=80/100 or 4/5
Answer:
Step-by-step explanation:
The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.
Perform the indicated multiplication, obtaining:
8x - 20 = 9x - 18.
Then combine like terms: -2 = x, or
x = -2.
To complete the formal check, substitute -2 for x in the first equation. This results in:
(1/3)(-4 - 5) = (3/4)(-2 -2), or
-3 = -3
... which is obviously true.
Answer:
"In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron."
