I hope this helps!
A brainliest will be appreciated.
Answer:
C. 4k - 3.
Step-by-step explanation:
(7 - 3k) - (4 - 5k) - (6 - 2k)
Distributing the negative over the last 2 parentheses:
= 7 - 3k - 4 + 5k - 6 + 2k
= -3k + 5k + 2k + 7 - 4 - 6
= 4k -3.
Explain the placement of the decimal point when dividing by a power of 10.
Answer:
what do you mean by this be more specific plz
Step-by-step explanation:
Answer:
When we divide a number by the power of ten the decimal point shifts towards left of that number. Mathematically for example,
[tex] \frac{6}{10} = 0.6 \\ \frac{54}{10} = 5.4 \\ \frac{234}{10} = 23.4 \\ \frac{132}{ {(10)}^{2}}= \frac{132}{100} = 1.32 \\ \frac{2345}{ {(10)}^{3} } = \frac{2345}{1000} = 2.345 [/tex]

Find the value of each variable in the parallelogram.
Answer:
u = 4; v = 18
because this is a parallelogram
=> 2u + 2 = 5u - 10
6 = v/3
<=> 3u = 12
v = 6.3
<=> u = 4
v = 18

Find the value in f each variable
Answer:
x=63°, y=47°, w=70°, z=121°
Step-by-step explanation:
Angles in a Triangle
To find the value of the variables given in the figure, we must recall some properties of the angles in a triangle and in a line:
The sum of all interior angles in a triangle is 180°The sum of all exterior angles in a triangle is 360°Two adjacent angles formed by the intersection of two lines add up to 180° (linear angles)The exterior angles of the triangle have the measures z-13, z, and z+10. They must add up to 360°, thus:
z - 13 + z + z + 10 = 360
Simplifying:
3z - 3 = 360
Adding 3:
3z = 360 + 3 = 363
z = 363/3
z = 121°
Now we use the bottom left vertex of the triangle, where the angles z-13 and w must add up to 180° because they are linear angles:
z - 13 + w = 180
Since z=123°
123 - 13 + w = 180
Rearranging:
w = 180 - 123 + 13
w = 70°
Similarly angles y and z+10 are linear, thus
y + z + 10 = 180
y + 123 + 10 = 180
Solving:
y = 47°
Finally, the sum of the interior angles of the triangle is 180°, thus:
x + 70 + 47 = 180
x = 180 - 70 - 47
x = 63°
Solution: x=63°, y=47°, w=70°, z=121°

Diet cola was on sale last week; it cost $10 for every 4 packs of cola. How much do 2 packs of cola cost?
Answer:
2 pack of cola would cost $5.
Step-by-step explanation:
the reason for this being is that
4 packs of cola = $10
2 is half of 4
5 is half of 10
$5<====
Answer:
I would say 5$
Step-by-step explanation:
You are going from 4 packs to 2 packs (so you are dividing by 2). So if you divide 10$ by 2 you get 5$

Which graph has a rate of change of zero?
Answer:
The second (bottom) graphStep-by-step explanation:
The first line is:
x = 3It has undefined rate of change
The second line is:
y = 3It has rate of change of zero (no change in y-value for any x-value)
Answer:
The first graph is : x=3Here, the rate of change is not defined.
The second graph : y=3Here, the rate of change is zero .i.e., y is independent of x.
Therefore, 2nd graph has a rate of change of zero.
A painting is 23 inches high and 11 inches wide. What is the diagonal length across the painting?
Answer:
the diagonal length is 25.50
Step-by-step explanation:
The computation of the diagonal length across the painting is as follows:
As we know know that
The Diagonal length would be
= [tex]\sqrt{w^2 + l^2}[/tex]
where
w = width
l = length
So, the diagonal length is
[tex]= \sqrt{23^2 + 11^2}\\\\= \sqrt{529 }+ 121} \\\\= \sqrt{650}[/tex]
Hence, the diagonal length is 25.50
You roll a 6-sided die.
What is P(not factor of 35)?
Simplify your answer and write it as a fraction or whole number.
Answer:
[tex]\huge\boxed{\text{P(not factor of 35) = } \frac{2}{3}}[/tex]
Step-by-step explanation:
We can use basic probability to find the probability that this roll is not a factor of 35.
First off, we know that with a six sided die there are 6 possible things we can roll.
1, 2, 3, 4, 5, or 6
Now, what are the factors of 35? The factors of 35 will be any whole number that can be multiplied by another whole number to get 35.
We know [tex]1 \cdot 35 = 35[/tex], so two factors are 1 and 35.We know [tex]5 \cdot 7 = 35[/tex], so two factors are 5 and 7.Therefore, the factors of 35 are 1, 5, 7, 35.
Both 5 and 7 are inside the range of 1-6. So the probability of rolling a side that's a factor of 35 will be [tex]\frac{2}{6} = \frac{1}{3}[/tex] since there are two factors and 6 possible options.
This means, logically, there is a [tex]\frac{4}{6} = \frac{2}{3}[/tex] chance of not rolling a factor of 35.
Hope this helped!

Answer:
C) 19
Step-by-step explanation:
The two angles next to each other are complementary angles meaning they add up to 90°. We can use this information to solve for y:
3y + 2 + 31 = 90
3y + 33 = 90
3y = 57
y = 19
