solve each inequality using addition and subtraction and graph it's solution set on a number line x + 8 > 14
Hi there!
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
x+8-8>14-8
Then, you subtract by the numbers from left to right.
14-8=6
The answer must have a positive sign.
Answer: →→ x>6
Hope this helps!

Jane’s favorite fruit punch consists of pear, pineapple, and plum juices in the ratio 5:2:3.
How much of each juice is needed to make 25 liters of this punch?
I got 12.5L for pear, 5L for pineapple, and 7.5L for plum. These were all right. Now, I have the second part I need help with:
How much punch can she make if she has only 6 cups of plum juice?
Answer:
20!
Step-by-step explanation:
trust me i just did this problem! is 20 :)
To calculate the amount of punch Jane can make with 6 cups of plum juice, we need to convert cups to liters and use proportions based on the original juice ratios. She can make approximately 4.8 liters of punch with 1.44 liters of plum juice, 2.4 liters of pear juice, and 0.96 liters of pineapple juice.
Explanation:Jane's favorite fruit punch consists of pear, pineapple, and plum juices in the ratio 5:2:3. To find out how much punch she can make with only 6 cups of plum juice, we need to set up a ratio based on the original proportions. First, we convert the given amount of plum juice to liters because the original recipe is in liters (1 cup is approximately 0.24 liters). Six cups of plum juice is roughly 1.44 liters.
Using the original ratio of 5:2:3 for pear, pineapple, and plum juice, and knowing that the amount of plum juice is 1.44 liters, we can set up the following proportions:
Plum Juice: 3 parts (original ratio) = 1.44 liters (actual)Pear Juice: 5 parts (original ratio) = x liters (actual)Pineapple Juice: 2 parts (original ratio) = y liters (actual)To find the values of x and y, we use cross multiplication:
For pear juice: (5/3) = x/1.44For pineapple juice: (2/3) = y/1.44By solving these equations, we find x (pear juice) is approximately 2.4 liters and y (pineapple juice) is approximately 0.96 liters. Adding these up, Jane can make a total of 4.8 liters of punch with the available plum juice.
The Mississippi River is the second longest river in the United States,second only to the Missouri River. The Mississippi River is about 23/25 the length of the Missouri River.if the Missouri River is 2,540 miles long,how long is the Mississippi River?
The length of the Mississippi River is approximately 2,336.8 miles.
If the Mississippi River is about [tex]\( \frac{23}{25} \)[/tex] the length of the Missouri River, and the Missouri River is 2,540 miles long, we can find the length of the Mississippi River by multiplying the length of the Missouri River by [tex]\( \frac{23}{25} \).[/tex]
Length of the Mississippi River = [tex]\( \frac{23}{25} \times \text{Length of the Missouri River} \)[/tex]
Substituting the given value for the length of the Missouri River:
Length of the Mississippi River = [tex]\( \frac{23}{25} \times 2540 \)[/tex]
To compute this:
[tex]\[ \frac{23}{25} \times 2540 = \frac{23 \times 2540}{25} \][/tex]
[tex]\[ = \frac{58,420}{25} \][/tex]
= 2,336.8
Therefore, the length of the Mississippi River is approximately 2,336.8 miles.

Estimation and mental math techniques, like knowing certain reciprocals, help to easily compute numbers mentally, a skill valuable in both academic and real-world settings.
Explanation:Estimation and mental math are key concepts when considering numbers that are easy to compute mentally. By using heuristics, such as knowing the reciprocals of numbers that multiply to 10, or by rounding numbers to nearest tens or hundreds, we can simplify computations and make them more manageable without the use of calculators or paper. This approach is particularly useful when dealing with real-world scenarios where exact numbers are not necessary and approximate values will suffice.
