Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1

Twice a number, increased by the
sum of the same number and five.
I
Answer:
2x + (x + 2)
Step-by-step explanation:
Let the number = x
"twice a number" means 2x
"increased by the sum of the same number and five" means to add x + 5, so the expression is
2x + (x + 2)

Put the equations in order from least to greatest number of solutions.
Answer:
Step-by-step explanation:
1). 3 - | x + 4 | = 10 No solutions
2). 1/2 | x | + 3 = 3 One solution x = 0
3). | x - 8 | - 4 = - 1 Two solutions x = 5 and x = 11
Step-by-step explanation:
i got it right with edmentum
The equation 3 - | x + 4 | = 10 doesn't have any solution and 1/2 | x | + 3 = 3 has one solution while | x - 8 | - 4 = - 1 has two solution.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
01) First equation
1/2 | x | + 3 = 3
1/2 | x | = 0
| x | = 0
x = 0 and -x = 0 ⇒ x = 0
So it has only one solution at x = 0.
02) Second equation
| x - 8 | - 4 = - 1
| x - 8 | = 3
-(x - 8) = 3 ⇒ x = 5 and (x - 8) = 3 ⇒ x = 11
So it has two answers at 5 and 11.
03) Third equation
3 - | x + 4 | = 10
In this no one solution is possible.

Home Depot, what is the amount, in dollars, in Jeremiah's bank account?
A $33.62
B. $219.22
C. $174.42
D. $42.22
Answer:
A $33.62

To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3
Answer:
-92.80+126.42=33.62
Step-by-step explanation
Since you owe $92.80 it would be a negative. So it would be like this.
126.42-92.80= 33.62
Or
-92.80+126.42=33.62

To determine the number of trout in a lake, a conservationist catches
185 trout, tags them and throws them back into the lake. Later,44 trout are caught;
11 of them are tagged. How many trout would the conservationist expect to be in the lake?
11/44 reduces to 1/4
1/4 of the trout caught were tagged.
185 trout were tagged
185 / 1/4 = 740
There are 740 total trout.
