Answer:
k = 4
Step-by-step explanation:
17 = 5k - 3
+3. +3
20/5 = 5k/5
4 = k
k = 4
Answer: k = 4
17=5k-3
1. In order to solve this linear equation, we'll need to group all the variable terms on one side, and all the constant terms on the other side of the equation. In the problem, term -3 will be moved on the left side. Notice the sign changes when you move it to the left.
17=5k-3 ⇒ 17 + 3 = (5k - 3) + 320 = 5k - 3 + 3
2. Add the numerical terms.
20 = 5k - (3 + 3) = 6. Note: We don't need the six in the 3rd step.
20 = 5k
3. Switch the variable term. (Ex: 3x + 9 ⇒ 9 + 3x)
20 = 5k ⇒ 5k = 205k = 20
4. We will need to isolate the variable, to do that, get rid of the coefficient that it multiples. We can do that by dividing 5 by both sides.
5k/5 ÷ 20/5 = 1k/45k/5
5. We'll need to reduce 5k/5 to its lowest terms. We can divide the factors that appear both in the numerator and denominator. If we look at 5k/5, 5 appears both in the numerator and denominator.
5k/5 ⇒ k = 2²· 5/56. Lastly, we can do the same thing as we did in the 5th step. That'll lead us to k = 2²
7. Solve for 2²
2 x 2 = 4.
Hence, our answer is 4.

Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer:
V=2.8cm^3
Step-by-step explanation:
The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.
Calculation of the pyramid:Since
perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.
So, here
we know that
volume of a pyramid = [tex]1/3(length * width * height)[/tex]
And,
perimeter of a square = [tex]4 * length[/tex]
6.9 = 4 x length
So,
length = 1.725
Now the volume is
[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]
= 2.8

Explain what the equation 3x = 6 means without using the word equal.
Explain why 2 is a solution of the equation
Step-by-step explanation:
1. 3 multiplied by x is the same value of 6
2. since 3x is on the left side we have to divide the equation by 3 on both sides which doesn't change the value of x, but it helps us get the value for x. so when you divide the equation by 3 the answer for x=6/2 which 2 divided by 6=3
Hope that helps :)

Answer:
A. The perimeter of the third triangle will be equal to the perimeter of the second triangle because the lengths of line segments are preserved during translations.
Step-by-step explanation:
When a shape is translated, it simply means it is moved. Nothing about it is being changed besides the location. Therefore, it will have the same perimeter because its sides are the exact same.

Caroline is planning on reducing her working schedule and only work 7 hours each day for 4 days a week work out the percentage reduction in Caroline's earnings if she decides to go ahead with her plan
The percentage reduction in Caroline's earnings if she decides to go ahead with her plan is 30%.
How to calculate the value?Since Caroline works 8 hours each day for 5 days a week and she's earns £11 per hour. The amount earned for the week is:
= (80 × 5 × £11)
= £440
When she is planning on reducing her working schedule and only work 7 hours each day for 4 days a week. The amount will be:
= (4 × 7 × £11)
= £308
The percentage reduction will be:
= Difference on amount / Old amount × 100
= (440 - 308) /440 × 100
= 132/440 × 100
= 0.3
= 30%

Find the area and the circumference of a circle with diameter 8yd
Answer:
25.12
Step-by-step explanation:
c = 2 pi r
d = 8 so r = 4
c = 2 * 3.14 * 4
c = 25.12
Answer:
Step-by-step explanation:
Given
Diameter (d) = 8 yd
radius (r) = d/2 = 8/2 = 4
Now
Area = π * r²
= 3.14 * 4²
= 50.24 yd²
Circumference
= π * d
= 3.14 * 8
= 25.12 yd
how can you determine if the association on scatter plot is strong or weak
Answer:

Given the kite below, if NO = 5 and OM = 12, what is the value of NM?
Answer:
NM = 13
Step-by-step explanation:
pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
a or NO = 5
b or OM = 12
c or NM = ?
plug in what is known:
⇒ [tex]5^{2} + 12^{2} = c^{2}[/tex]
⇒ [tex]25 + 144 = c^{2}[/tex]
⇒ 169 = [tex]c^{2}[/tex]
square root each side of the equation:

State whether 2.5 + π is rational or irrational. Explain.
Answer: 2.5 + π is an irrational number.
Step-by-step explanation:
Irrational numbers are numbers that can not be written as the quotient of two integer numbers, and they have an infinite number of digits after the decimal point (such that there is not periodicity in these digits).
So suppose that we have an irrational number and we add 1, then the infinite digits after the decimal point will still be there, so the sum will be also an irrational number.
The same can be seen for the sum between an irrational number and a rational number, where the infinite number of decimals after the decimal point will still be there (because the rational numbers have a finite or infinite but periodical decimals after the decimal point), so the sum between an irrational number and a rational number is always irrational.
In this case, we have the addition:
2.5 + π
Which is the sum of a rational number and an irrational number, so we can conclude that this is an irrational number.

Given:
AD is an angle bisector in triangle ABC. [tex]m\angle CAB=44^\circ, m\angle ACB=72^\circ, m\angle ABC=64^\circ[/tex].
To find:
The value of [tex]m\angle ADC[/tex].
Solution:
AD is an angle bisector in triangle ABC.
[tex]m\angle CAD=m\angle BAD=\dfrac{m\angle CAB}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=\dfrac{44^\circ}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=22^\circ[/tex]
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property in triangle CAD, we get
[tex]m\angle CAD+m\angle ADC+m\angle ACB=180^\circ[/tex]
[tex]22^\circ+m\angle ADC+72^\circ=180^\circ[/tex]
[tex]m\angle ADC+94^\circ=180^\circ[/tex]
[tex]m\angle ADC=180^\circ-94^\circ[/tex]
[tex]m\angle ADC=86^\circ[/tex]
Therefore, the angle of angle ADC is [tex]86^\circ[/tex].
