Whats the answer to these? (These are called Proper fractions.)
Jeremiah ran for 3/10 of a mile and then walked another 2/5 of a mile. How far did he travel in all?
Daniel read 4/5 books and Edgar read 1/2 books. How many more books did Daniel read than Edgar?
Jared drove 2/8 miles to the restaurant. He drove another 1/4 miles to the mall. How many miles did he drive in all?
Answer to the first question: 7/10ths of a mile
Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.
Answer to the second question: Daniel read three (3/10) more books
Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.
Answer to the third question: 2/4 mile (or 1/2 a mile)
Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.
Answer and Step-by-step explanation:
1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.
[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]
[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]
Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.
2. Convert the denominators of all the fractions to have a 10.
[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]
[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]
Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.
3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]
Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

Find the solution set of the inequality
5x + 13 > -37.
x ?
Answer:
x > -10
Step-by-step explanation:
5x + 13 > -37
subtract 13 from each side:
5x > -50
x > -10
Answer:
X >/ -10 (imagine this is more or equal to symbol lol)
Step-by-step explanation:
1. subtract 13 from both sides
5x +13-13 >/ -37 -13
2. Simplify
5x >/ -50
3. solve for x (which means divide by 5)
5x/5 >/ -50/5
x>/ -10

Answer and Step-by-step explanation:
We are told that there is 24 cupcakes, which total up to be 36 dollars.
c will represent One cupcake.
We would do 36 divided by 24 to find the cost of One cupcake.
[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]
Each cupcake (c) is equal to $1.5.
Equations that would get us to this would be:
36/24 = c
36 = 24c

Write an equation of a line with the given slope and y intercept from the graph
Answer:
y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1
Step-by-step explanation:
y = mx + b
b is the point on the y
y = -1
so
b = -1
now the slope
m = rise/run
m = 3/2
so
y = 1.5x - 1
Plz mark as brainliest if correct!!!
Answer:
y=3/2x-1
Step-by-step explanation:
slope:3/2
y-intercept:-1
y=3/2x-1

Answer:65
Step-by-step explanation:
Last year, 12 hydrange bushes had a mean of 14 blooms each, with a standard deviation of 2. The dot plot shows the number of blooms on the same bushes this year after a new plant food is used. What conclusions can you draw about the use of the new plant foor and the number of blooms?
Answer: The plant food produces more blooms on average, but the results aren't as consistent as before.
========================================
Explanation:
The dot plot leads to this data set
{8, 12, 12, 17, 17, 18, 18, 18, 19, 19, 20, 23}
Using pencil/paper, or using technology, you should find the following properties of this data set
mean = 16.75sample standard deviation = 4.11The second value is approximate. Both the mean and standard deviation are larger than their original counterparts (mean = 14 and std dev = 2).
Since the mean is larger, this means the data points have been shifted to the right further. The larger standard deviation tells us that the data is more spread out.
So it appears this new plant food has made the number of blooms increase overall, but it's also made the data more inconsistent. A smaller standard deviation would mean a more narrow set of points and therefore more consistent values (they'd all be clumped around the mean better).

Answer:
x = 119
z = 28
Step-by-step explanation:
To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.
x + 61 = 180
Subtraction: x = 119
To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.
61 = 5z - 79
Addition: 140 = 5z
Division: 140/5 = 5z/5
Final Answer = 28 = z
The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?
Answer:
24 kilometers
Step-by-step explanation:
Given
Represent the distance with x
[tex]x = 2km\ 400m[/tex]
Required
The distance covered for 5 days (i.e. Monday to Friday)
First, we calculate the distance covered in a day
He covers the same distance when going to school and when coming back from school.
So, the daily distance is:
[tex]Daily = 2 * x[/tex]
[tex]Daily = 2 * (2km\ 400m)[/tex]
[tex]Daily = 4km\ 800m[/tex]
In 5 days, he covers:
[tex]5\ days = 5 * Daily[/tex]
[tex]5\ days = 5 * (4km\ 800m)[/tex]
[tex]5\ days = 5 * (4km+ 800m)[/tex]
Open bracket
[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]
[tex]5\ days = 20km+ 4000m[/tex]
Convert m to km
[tex]5\ days = 20km+ 4km[/tex]
[tex]5\ days = 24km[/tex]
