Answer:
x = -10
Step-by-step explanation:
First I would expand by distributing the left side.
Using distribution the new equation would be: -2x - 8 = 12
Now, I would move constants to one side and keep variables on the other side.
Doing this, my new equation would be -2x = 20
Now I would divide both sides by negative 2, giving the answer x = -10
Answer: -10

Amy has $725 in savings. She plans to save an additional $25 per month. What is the number of additional months Amy will need to save money in order to have exactly $1,000?
A.11
B.29
C.40
D.69
Answer:
11 months
Step-by-step explanation:
We know that Amy has a saving of $725 which she needs to make it up to $1000 by saving $25 each month.
This means that Amy needs to save $1000 - $725 = $275 more dollars to have exactly $1000 dollars.
If Amy saves $$25 each month, then the number of months that she needs to save money will be = 275 / 25 = 11 months

Answer:
a. 121
b. 32100
c. 0.2
d. 400
Step-by-step explanation:
a. Quick disclaimer: If there's a decimal point on the divisor, in this case it would be .05, you have to move the decimal point until it has no decimal, in this case .05 would become 5.0 or just 5. The other number also has to have it's decimal point moved as much as the divisor, in this case two times, so it would be from 6.05 to 605. So with this in mind: 605/5 = 121
b. 96.3/.003 = 96300/3 = 32100
c. 0.12/0.6 = 1.2/6 = 0.2
d. 3.2/.008 = 3200/8 = 400

Step-by-step explanation:
You go to the one hour than go up to where the line is and find out what the number is
Answer:
Step-by-step explanation:
Ok, so to solve this problem, you need to find the slope of the line. You know this is what you need to find because units for slope is the y-axis units (dollars) divided by the x-axis units (hours), and your answer must be in dollars per hour based on the question. To find your slope, you use the formula (y2-y1)/(x2-x1). Basically, pick any two points on the graph. I will use (2,20) and (4,40). Now, find the change in x (4 - 2, or 2) and the change in y (40 - 20, or 20) and divide the change in y by the change in x (20/2) to get your answer.

2/3 of all your books are fiction. 1/6 of those are historical fiction.
What fraction of all your books are historical fiction?
A.1/9
B.1/18
C.1/3
D.1/2
Answer:
1//18
Step-by-step explanation:
2/3 * 1/6= 1/18
You first do 2*1
Then 3*6
Answer: A. 1/9
Step-by-step explanation:
to find what fraction of all your books is historical fiction, you would multiply how the fraction of all your books that are fiction by the fraction of fictional books that are historical fiction.
this gives you 2/3 times 1/6.
from there you simply multiply the numerators (2x1=2)
and the denominators (3x6=18)
leaving you with 2/18
but that can be simplified, giving you the final answer of 1/9

Answer:
20×4=80
4×2×10=80
Step-by-step explanation:
To estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally.
One method of estimation is to round all factors to the biggest digit (place value) they have.

why are radioactive isotopes not useful for dating sedimentary rocks?
Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.
