Pls help
Answer:
2k/5 + 1 + -k+1/3
Step-by-step explanation:
(2k - 7)/5 + 1 - 1 x (k - 1)/3
Simplify
Combine multiplied terms into a single fraction
2k - 7/5 + 1 - 1 x k - 1/3
2k- 7/5 + 1 + -1(k - 1)/3
Distribute
2k - 7/5 + 1 + -1(k - 1)/ 3
2k - 7/5 + 1 + = -k + 1/3
Solution
2k - 7/5 + 1 + -k + 1/3
Answer:
[tex]\frac{k-1}{15}[/tex]
Step-by-step explanation:
[tex]\frac{(2k - 7)}{5} + 1 - \frac{(k-1)}{3}[/tex]
[tex]\frac{3(2k -7)}{3 ( 5)} + \frac{15 * 1}{15 * 1} - \frac{5(k-1)}{5 * 3}[/tex]
[tex]\frac{6k - 21}{15} + \frac{15}{15} - \frac{5k - 5}{15}[/tex]
[tex]\frac{(6k - 21) + 15 - (5k - 5)}{15}[/tex]
[tex]\frac{(6k - 6) - (5k - 5)}{15}[/tex]
[tex]\frac{6k - 6 - 5k + 5}{15}[/tex]
[tex]\frac{k - 1}{15}[/tex] <------This is your answer

y=−4x−3
y=−2x+1
x=x=x, equals
y=y=y, equals
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .

-pound bag of seeds states that it will cover an area of 7575 square feet. How many square feet do the seeds cover per pound?
Answer:
[tex]183.63[/tex] square feet area is covered by seeds per pound
Step-by-step explanation:
Given
[tex]41\frac{1}{4}[/tex] pound bag of seed cover an area of [tex]7575[/tex] square feet
[tex]\frac{165}{4}[/tex] pound bag of seed cover an area of [tex]7575[/tex] square feet
Or
[tex]7575[/tex] square feet area is covered by [tex]\frac{165}{4}[/tex] pound bag of seed
Area in square feet covered by one pound bag of seed
[tex]= \frac{7575}{\frac{165}{4} } \\= \frac{7575 * 4}{165} \\= 183.63[/tex] square feet

plz help!! A jar contained 6 red marbles, 10 green marbles, and 8 blue marbles. A marble was selected at random, the color was recorded, and the marble was placed back in the jar. The table shows the results after 60 trials. What was the relative frequency of selecting a red marble? Outcome Number of times outcome occurred Red 13 Green 30 Blue 17
Give your answer as a fraction in simplest form.
Answer:
To calculate the relative frequency, first we need to know what exactly is and how to calculate it.
Relative frequency is the ratio between the absolute frequency (how many repetitions have a specific outcome) and the total outcomes. Also, this type of frequency is used to show the representation that some data have over the whole distribution.
So, in this case, we need to just divide 13, which belongs to red marble's results, to 60 which is the total outcomes, as it's presented:
13redmarble Fr = -------------------------
60 totalmarbles
Normally, relative frequency is shown as a percentage multiplying this result by 100. Therefore, 22% is the approximate percentage of the relative frequency, which means that 22% is the representation of red marbles outcomes of the whole distribution, or we can say it as a probability: there's 22% of chances when someone extract a marble, it will be red.

The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
