Answer:
x = 0, Need the steps?
STEPS:
9x - 7 = -7 (Original Problem)
9x = 0 (Add 7 to both sides)
x = 0 (Divide both sides by 9)
Answer:
Step-by-step explanation:
(3) 9x-7=7
First multiply 3 by 9x to get 27x
27x-7=7
Then add 7 to both sides
27x-7+7=7+7
27x=14
27x/27=14/27
x=14/27

Think about the methods you have for comparing two probabilities to decide which is greater. In your Learning Log, create an example and explain two different strategies for comparing probabilities. Title this entry "Comparing Probabilities" and label it with today's date.
Answers
Answer:
Step-by-step explanation:
Probabilities are basically values determining how likely something is to happen. These values are usually represented in fractions or percentages which are the two main strategies as well for comparing probabilities. For comparing probabilities through fractions we would try to make sure the denominators are equal and then compare the numerators. The higher numerator is the probability with the highest chance of something happening. For example...
[tex]\frac{3}{4} > \frac{1}{4}[/tex] ... 3/4 is a much higher probability than 1/4
The second strategy would be using percentages in the same way. The higher percentage is the one with the highest probability while the lower percentage is the one with the lower probability.

First, we see that at 0 minutes, the container is completely full at 900ml. If you look on the graph, you can see that the container is at 800ml after 10 minutes. This is key because it tells us that the container leaks 100ml every 10 minutes. We can then figure up that 900, when losing 100ml every 10 minutes, will eventually run dry after 90 minutes. You can set up a proportion to check your work, which would look like this: 10 over 100 is equal to x over 900.
Ron remembers that the second factor was a decimal. Based on the placement of the decimals in the first factor and the product, which must be true of the second factor? The decimal could be one-tenth. The decimal could be two-tenths. The decimal could be five-tenths. The decimal could be seven-tenths.
Answers
Answer: The decimal could be two-tenths.
Step-by-step explanation:
Two tenth as a product of decimals, 2/10 = 0.2. What this means is that a tenth is on of equal parts of something. e.g i received two tenth of the 30 bananas, what this implies is that he received 6 pieces of the bananas and this can be gotten by 2/10*30 = 6.

−9x+5<17 and 13x+25<−1 solve for x
Answers
-9x + 5 < 17
Subtract 5 from both sides:
-9x < 12
Divide both sides by -9, and because you are dividing by a negative value the inequality sign gets reversed:
X > -12/9
Simplify:
X > -4/3
13x + 25 < -1
Subtract 25 from both sides:
13x < -26
Divide both sides by 13:

Find the value of X
(5x+4)°+(8x-71)°
Answers
Answer:
x = -4/5
Step-by-step explanation:
Solve for x:
(5 x + 4) (8 x - 71) = 0
Split into two equations:
5 x + 4 = 0 or 8 x - 71 = 0
Subtract 4 from both sides:
5 x = -4 or 8 x - 71 = 0
Divide both sides by 5:
x = -4/5 or 8 x - 71 = 0
Add 71 to both sides:
x = -4/5 or 8 x = 71
Divide both sides by 8:
Answer: x = -4/5 or x = 71/8
