Answer:
the LCD is a) (2x+1)(x-3)
Step-by-step explanation:
step 1.)
factorise: 2x²+1- 5x-3 becomes (2x+1)(x-3) when you factorise it and the 2x+1 stays (2x+1).
step 2.)
since 2x+1 are in both denominators you only write it once and don't forget to include x-3 as an LCD
therefore (2x+1)(x-3) is the LCD.
What value of x makes the equation below true 6x-7=26
Answer:
11/2
Step-by-step explanation:
6x−7=26
Step 1: Add 7 to both sides.
6x−7+7=26+7
6x=33
Step 2: Divide both sides by 6.
x= 11/2

Bags of sugar come in 3 sizes:
Small bag: A 250 g bag costs 85p.
Medium bag: A 500 g bag costs £1.90.
Large bag: A 3 kg bag costs £3.90.
Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments.
Answer:3kg of small bag costs £10.20 while 3kg of the medium bag costs £11.40. Hence, the bag with better value which is the cheapest is a 3kg of the big bag which costs £3.9

PLS HELP!!!!!!!! will mark brainliest!! questions 4, 6, 8. im so lost ahhhh
Answer:
when you ask multiple questions at once, it feels more like i'm doing your HW for you, not that i'm helping you understand , i'll answer these but you really should have been able to do these if you really did all the others. Did you just get tired out? Why can't you do 4, 6, 8? what is it that you don't understand?
Step-by-step explanation:
4) old price = 120 to new price = 240
they ask what is the percent change
How much is the change ( in amount )
the "How much is obvious right? Old price 120 , new price 240.. change is $120
the percent is change / old price = 120 / 120 = 1 and to put it in percent , multiply by 100 , so 100 % change
6) old price = 250 amount of change -100
so what percent of 250 is 100
100 / 250 = 0.4 to get it in percent multiply by 100 = 40%
old price + change = new price
250 + ( -100) = 150 new price is $150
8) 5% mark up , amount of change = $2.50
so 5% of what = 2.50 ?
X* 5% = 2.5
X* 0.05 = 2.5
X=2.5/0.05
X= $50 was the old price
old price + amount change = new price
50 + 2.50 = 52.50
$52.50 is the new price
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

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.

Step-by-step explanation:
12(8) + 4(6) = 120
Answer:
96ft
Step-by-step explanation:
First we can find the rectangle which would be
6*12=72
then we can find the triangle, since their are two triangles we can combine them to make a rectnagle so we can just do
6*4=24
then we can add them together

porfavor necesito ayuda cuanto es -14x>-3
x < 3 / 14 or x < 0.2143
can someone please help me?!
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

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

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).
Find the value of each variable.

ifā=r, then which of the following are true statements?
Check all that apply.
O A. n1/r = a
✓ B. = a
c. a1/nur
O D. a' = n.
Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ
