Answer:
a = {-5/6 , 1}
Step-by-step explanation:
6a² - a -5 = 0
Factor
(6a + 5)(a - 1) = 0
Root 1
6a + 5 = 0
6a = -5
a = -5/6
Root 2
a - 1 = 0
a = 1
Solution set
a = {-5/6 , 1)

Find the number if 1/3 of it is 12?
Answer:
36
Step-by-step explanation:
If 1/3 of x is 12, we can make an equation.
x/3=12
So now we isolate x.
x=36
Answer:
36
Step-by-step explanation:
of means multiply and is means equals
1/3 * n = 12
Multiply each side by 3
3 * 1/3 n = 12 *3
n = 36

The perimeter of the figure below is 141.8ft. Find the length of the missing side
Answer:8.6
Step-by-step explanation:
The easiest way to do this is for you to subtract all the sides from the total perimeter since the perimeter is all of the sides added and your remainder is your answer
Hope this helps
Answer:
8.6 ft
Step-by-step explanation:
Subtract the sum of the known sides from the total in order to find the missing side length.
141.8 - (44.8 + 12.9 + 12.9 + 22.4 + 13.4 + 13.4 + 13.4) = ?
141.8 - (133.2) = ?
8.6 = ?

write an equivalent expression for 3/5x + 2/5 + 3/5x
please i will give brainliest
Answer:
= 3/5(x) + 3/5(x) + 2/5
= 6/5(x) + 2/5
= 2/5 (3x+1)
Step-by-step explanation:
Answer: [tex]\frac{6}{5}x + \frac{2}{5}[/tex]
This is the same as writing (6/5)x + 2/5
===================================================
Explanation:
Ignore the fraction [tex]\frac{2}{5}[/tex] for now.
The other terms will combine together since they are like terms. We'll add those terms to get:
[tex]\frac{3}{5}x+\frac{3}{5}x\\\\\left(\frac{3}{5}+\frac{3}{5}\right)x\\\\\frac{3+3}{5}x\\\\\frac{6}{5}x\\\\[/tex]
Then we tack on the [tex]\frac{2}{5}[/tex] we ignored earlier to get the final answer of [tex]\frac{6}{5}x+\frac{2}{5}[/tex]
Hi guys, I really need help, I reckon this is easy for you but I'm low-key disabled and need help with this question so please help me thx. <3
Answer:
15, 8, 66%, 40
Step-by-step explanation:
Hi! ok so in ogive charts its really about finding the corresponding data points and sometimes it's a lot of estimation so these answers may not be exact but they'll be close.
In the image, you'll see a bunch of lines, basically what youre doing is finding the corresponding frequency of the dollars or vice versa.
question a)
50 dollars or less, so the area of 50 dollars and below that.
from the chart we can see that this lines up to around 15 people.
question b)
now this one is a little bit more challenging, but you can use the same process as you did for the first question. so we can see who spent 100 dollars or less. this value is around 42 (just from looking at the graph)
we know if you didn't spend 100 dollars or less, you must have spent more than that.
so take 50-42=8
around 8 people spent 100 dollars or more.
question c)
basically the same question as the first but more calculations are involved. from the graph we can see around 33 people spent 80 dollars or less. but the question is asking the percentage. so what percent of 50 (people) is 33.
33/50 = 0.66
around 66%
question d)
80th percentile means less than or equal to 80% of the frequencies/the data. so we first need to find what value that is in terms of frequency.
50 times 0.8 = 40
40 people
now just plot that on the graph (sorry i did it wrong in the image)
Oscar is buying soil for his plants. He needs to fill one pot with 8 cups of soil and another pot with 3 gallons of soil. If
the price of soil is $2.50 per quart, how much, in dollars, will he pay in all? You may use the conversions to help you

1 quart = 2 pints
1 gallon = 4 quarts
1 gallon = 3.875 liters
Enter your answer in the space provided
Answer:

Bailey has been studying wait times at two restaurants in her hometown.
Which TWO statements BEST describe the relationship between the restaurant wait times?
A
If two sets of data have the same median, they will also have the same range.
B
The mode can not be used to compare this data because there are multiple modes for restaurant B.
C
There is less of a wait time for restaurant A because the range of the data is less than the range of the data for restaurant B.
D
When comparing two sets of data, the closer the means of the data are, the greater the data will visually overlap when graphed.
E
When there is a large difference between the means in two sets of data, there will also be a large difference in the medians of the data sets.
