Answer:
=6x−3
Step-by-step explanation:
Let's simplify step-by-step
4x+3(2x−1)−4x
Distribute:
=4x+(3)(2x)+(3)(−1)+−4x
=4x+6x+−3+−4x
Combine Like Terms:
=4x+6x+−3+−4x
=(4x+6x+−4x)+(−3)
=6x+−3
Answer:
6x - 3
Step-by-step explanation:
4x + 3(2x - 1) - 4x
Distribute, multiply every term inside the parenthesis by the term outside of it,
4x + (3)(2x) + (3)(-1) - 4x
Simplify,
4x + 6x - 3 - 4x
Simplify further, combine like terms,

circumference of circle whose radius is 7cm
Answer:
43.98 cm
Step-by-step explanation:
[tex]C=2\pi r[/tex] where r is the radius
Plug the radius 7 cm into the equation as r
[tex]C=2\pi (7)\\C=14\pi \\C=43.98[/tex]
Therefore, the circumference of the circle is approximately 43.98 cm.

Directions: Solve for x.
Answer:
x = 6
Step-by-step explanation:
From the given picture,
ΔABC and ΔADE are the similar triangles.
By the property of similar triangles,
Corresponding sides of the similar triangles are proportional.
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{x+18}{x}=\frac{28}{(28-21)}[/tex]
7(x + 18) = 28x
7x + 7×18 = 28x
28x - 7x = 126
21x = 126
x = [tex]\frac{126}{21}[/tex]
x = 6
help plzzzzz! it's math and I'll give 30 points
Answer:
[tex]\sqrt{45}[/tex]
Step-by-step explanation:
Hi there,
In order to solve this problem, you have to know the Pythagorean Theorem:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
We can see from the graph that line segment ML and LN are 6 and 3 units respectively. Since we know the lengths of two sides of the triangle, we can use the theorem above to find the hypotenuse (MN).
⇒ [tex]6^{2}[/tex] + [tex]3^{2}[/tex] = [tex]c^{2}[/tex]
⇒ 45 = [tex]c^{2}[/tex]
⇒ c = [tex]\sqrt{45}[/tex]
Hope this explanation helps. Cheers.

Find the volume of the irregular
figure.
2 cm
2 cm
?
cm3
4 cm
5 cm
2 cm
2 cm
Answer:
24 + 12 = 36
Step-by-step explanation:
find the volume of the upper left part by finding the dimensions
it already gives 2 side lengths: 2 and 2. To find the 3rd side length you can take 5 - 2 to get 3. 3*2*2 = 12
find the volume of the bottom portion by finding the dimensions. we are given 2 sides again: 2 and 2. to get the upper long side, we can do 4 + 2 to get 6. 6*2*2 = 24
24+12= 36cm^3

Dale and 2 friends share one fourth of a cake. Each piece is the same size. Dale believes each piece of cake has an angle measure of 45°. Is Dale correct?
Answer:
dale is not correct
the correct angle is 30 degrees
Step-by-step explanation:
A cake is shaped like a circle
the total sum of angles in a circle is 360 degrees
If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees
If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees
the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong
Answer:
dale is incorrect

Given the following perfect square trinomial, fill in the missing term
4x2 + ___x + 49
Answer:
Below.
Step-by-step explanation:
Taking the square roots of the 2 given terms we write it as a binomial
(2x + 7(2x + 7)
This = 4x^2 + 14x + 14x + 49
= 4x^2 + 28x + 49

Due to weather mark walk to school day of the 20 days in february what would be the fraction representation for the number of days he walk to school what will be the percent of the days in which mark walk to school
Tbe question doesn't state the number of days he walked to school out of 20 school days in the
Month of February.
Answer:
Kindly check explanation
Step-by-step explanation:
To. Obtain the fractional representayion for the number of days he walked to school ;
Let the number of days he walked to school = 10 (this is an hypothesized value)
Number of school days in February = 20
Fraction = 10 /20 = 0.5
The percentage of times walked to school : multiply the fraction obtained above by 100%
0.5 * 100% = 50%
Just put the desired value and proceed uSing the steps described above.

Answer:
mean; the average of George's scores is the mean = 83.4
Step-by-step explanation:
The value that best describes George's scores is the mean that has a value of 83.4.
What is the mean?
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number. The mean makes use of all the data in the data set.
Mean = sum of the numbers / total number
(70+ 92 + 70 + 90 + 95) / 5 = 83.4.

A store is running a sale where all of the items are 35% off the normal price. The price of a video game you want to buy is normally $61.97. What is the sales price of the game
Answer:
Discounted price= $40.28
Step-by-step explanation:
Giving the following information:
A store is running a sale where all of the items are 35% off the normal price. The price of a video game you want to buy is normally $61.97.
To calculate the discounted selling price, we need to use the following formula:
Discounted price= selling price*(1 - discount rate)
Discounted price= 61.97*(1 - 0.35)
Discounted price= $40.28
A pizza has 3,000 calories. If the pizza is cut into 8 slices, how many calories are in 3 slices of pizza?
Answer:
1125 calories
Step-by-step explanation:
3000 divided in 8 slices is 375 calories per piece.
3 pieces with 375 cals per 1125
Answer:
1125 calories
Step-by-step explanation:
Find how many calories are in one slice by dividing 3000 by 8:
3000/8
= 375
Find how many calories are in 3 slices by multiplying 375 by 3
375(3)
= 1125
So, in 3 slices of pizza, there are 1125 calories

Answer:
44 minutes
Step-by-step explanation:
Given that :
Start time = 1:37 pm
End time = 2:21 pm
The time difference is obtained by subtracting the start time from the end time :
. End time - start time
2:21 pm - 1:37 pm
From 1:37 pm to 2 pm = 23 minutes
From 2 pm to 2:21 pm = 21 minutes
Total minutes = (23 + 21) minutes = 44 minutes
