Answer:
A. 4x+7
Step-by-step explanation:
What is the sum of 4x and 7?
Add 4x + 7
A. 4x+7B. 3x
C. 11x
D. 3
Answer:
A. 4x+7
Step-by-step explanation:
4x has x-term as a variable while 7 only remains as a constant. Therefore, you cannot combine both terms as 11x since 4x and 7 are not like term.
Like terms are terms that have same variables and degrees. Some examples are:
2x and x are like term.3x and 8x are like term.Non-like terms are terms that have different variables and degree. Some examples are:
x and y are not like term.x² and x are not like term.Like terms operation:
2x + x = 3x4x + 5x = 9x9z + 2z = 11zNon-like terms operation:
2x + 3y remains as itself.sum of 4 and 7x is 4 + 7x.Let me know if you have any questions.
Find the value of x in
2x + 3x = 20+x
Hey there!
2x + 3x = 20 + x
5x = 20 + x
20 + x = 5x
SUBTRACT x to BOTH SIDES
5x - x = 20x + x - x
5x - 1x = 20x + 1x - 1x
SIMPLIFY IT!
4x = 20
DIVIDE 4 to BOTH SIDES
4x/4 = 20/4
SIMPLIFY IT!
x = 20/4
x = 5
Therefore, your answer is: x = 5
Good luck on your assignment & enjoy your day!

Answer:

Step-by-step explanation:
When you have a coefficent in front of a logarithm function, you can take the argument to the power of that coefficient. For example, the 3 in front of the logarithm can be brought into the argument, and you can take 'x' to the third power. You get:
[tex] log_{4}( {x}^{3} ) = log_{4}(32) + log_{4}(2) [/tex]
When you add logarithms, it is equivalent to multiplying their arguments:
[tex]log_{4}( {x}^{3} ) = log_{4}(32 \times 2) = log_{4}(64) [/tex]
Since both sides are log base 4, the arguments must equal each other:
[tex] {x}^{3} = 64[/tex]
[tex]x = \sqrt[3]{64} = 4[/tex]
here it is, this is ur answer x=4

A volleyball player hits a ball from a height of 6 feet with an initial vertical velocity of 16 feet per second. What is the maximum height of the volleyball? Assuming it is not hit by another player, when will the volleyball hit the ground? Round the answers to two decimal places if necessary.
The maximum height of the volleyball is ___
feet.
The volleyball will hit the ground after ___
seconds.
Considering a quadratic equation, it is found that:
The maximum height of the volleyball is of 19.06 feet.The volleyball will hit the ground after 3.6 seconds.What is the quadratic equation for an object's height?Considering the height in feet, it is given by:
h(t) = -4.9t² + v(0)t + h(0)
In which:
v(0) is the initial velocity.h(0) is the initial height.In this problem, we have that h(0) = 6, v(0) = 16, hence the equation is given by:
h(t) = -4.9t² + 16t + 6
Which is a quadratic equation with coefficients a = -4.9, b = 16, c = 6. Hence the maximum height is found as follows:
[tex]\Delta = b^2 - 4ac = 16^2 - 4(-4.9)(6) = 373.6[/tex]
[tex]h_{MAX} = -\frac{\Delta}{4a} = -\frac{373.6}{-4(4.9)} = 19.06[/tex]
The maximum height of the volleyball is of 19.06 feet.
It hits the ground at the roots, hence:
The solutions are:
[tex]x_1 = \frac{-16 + \sqrt{373.6}}{-9.8} = -0.34[/tex]
[tex]x_2 = \frac{-16 - \sqrt{373.6}}{-9.8} = 3.6[/tex]
Time is a positive measure, hence:
The volleyball will hit the ground after 3.6 seconds.

your answer as a fraction in simplest terms. Then, express the labeled angle in radian
measure.
225°
Answer:
Fraction: 5/8
Radians: 5pi/4 Radians
Step-by-step explanation:
1A Fraction
A circle has a total of 360 degrees, in order to solve the first part we must use this preknowledge.
As we are given 255 degrees, we simply order a fraction:
Degrees Given/360 Hence,
255/360
Simplify
5/8
1B Radians
In order to convert degrees to radians we use a simple trick, we must multiply the degree measure (225) by pi/180 because a full circle = 2pi radians or 360 degrees hence,
225 x pi/180
Simplify
5pi/4 radians

Solve for x
Show work
Isolate the absolute-value term:
2 |3x - 5| - 4 = 12
2 |3x - 5| = 8
|3x - 5| = 4
Recall the definition of absolute value:
[tex]|x| = \begin{cases}x & \text{if }x \ge0\\-x&\text{if }x<0\end{cases}[/tex]
We consider two cases:
• If 3x - 5 ≥ 0, then |3x - 5| = 3x - 5, and the equation resolves to
3x - 5 = 4
3x = 9
x = 3
• Otherwise, if 3x - 5 < 0, then |3x - 5| = -(3x - 5) = -3x + 5, hence
-3x + 5 = 4
-3x = -1
x = 1/3

The range Girls Choose
The mean Choose.
Answer:
RangeThe range of the data is the difference between the largest data value and the smallest data value.
Therefore, the ranges are:
Boys: 10 - 3 = 7
Girls: 9 - 5 = 4
So the boys have a larger range than the girls.
MeanTo calculate the mean, add up all the data values then divide by the number of values.
[tex]\textsf{Mean of Boys}=\dfrac{3+6+7+7+8+8+8+8+9+10}{10}=\dfrac{74}{10}=7.4[/tex]
[tex]\textsf{Mean of Girls}=\dfrac{5+6+6+6+7+7+7+8+8+9}{10}=\dfrac{69}{10}=6.9[/tex]
So the boys have a higher mean than the girls.

Answer: 960^3 cm or 960 cubic centimeters
Step-by-step explanation:
Cubic because measuring 3 dimensions.
32x45 = area of given face
32x45= 1440
height of water = 10 cm
so,
area of given face x 10 =
32x45x10 or lxwxh (Volume)
so
1440x10= 14,400
1440x8= 11,520
so 14,400 - 11,520 = 2880
V of three plants = 2880
so, 2880/3 = volume of one plant
2880/3=960
V of singe plant = 960 units ^ 3
The difference in volumes represents the total volume of three plants, so answer should be divided by 3.

Answer: one plastic water plant volume = 960 cm³
Step-by-step explanation:
Total volume = Water Volume + 3 plants volume
Total Volume = 32 cm x 45 cm x 10 cm = 14 400 cm³
Water volume = 32 cm x 45 cm x 8 cm = 11 520 cm³
3 Plants volume = 14,400 cm³ - 11,520 cm³ = 2880 cm³
1 Plant volume = 2,880 cm³ : 3 = 960 cm³
