(2k-7)/5+1-(k-1)/3
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]

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 .

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.

Answer:
13
Step-by-step explanation:
we know both triangles are congruent, so we can make an equation
3x+7=10x-7
take 3x from both sides
7=7x-7
14=7x
x=2
20-7=CAD
m<CAD is 13
The value of the angle CAD in the figure given is 13°.
So, the correct option is 1.
Given is a figure, we need to find the measure of the angle CAD,
To find the required measurement we will show the triangles ABD and ACD are congruent,
So, considering the Δ ABD and Δ ACD,
BD ≅ DC [marked in the figure]
∠B ≅ ∠C [all the right angles are ≅]
DA = DA [common in the both Δs]
Hence, Δ ABD ≅ Δ ACD by SSA rule.
We get, ∠CAD ≅ BAD by CPCTC.
Therefore,
3x + 7 = 10x - 7
Combining the like terms,
10x - 3x = 7 + 7
7x = 14
x = 2
Put x = 2 in ∠CAD = 3x + 7,
∠CAD = 3(2) + 7
∠CAD = 6 + 7
∠CAD = 13°
Hence, ∠CAD = 13°.

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

Solve, by completing the square, x^2=22x-5, leave your answer in surd form
Answer:
a) The complete square form = ( x-11)² = 116
b) x = 11 + 2√29
Step-by-step explanation:
Step(i):-
Given equation x² = 22x -5
⇒ x² - 22x + 5 =0
⇒ x² - 2× 11 x + (11)² -(11)² + 5=0
⇒ ( x- 11)² -121 +5 =0
⇒ ( x-11)² = 116
The complete square form = ( x-11)² = 116
Step(ii):-
⇒ (x-11) = √116 = √29 ×√4
⇒ x-11 = 2√29
⇒ x = 11 + 2√29

Which of the following functions models Angels savings?
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.
