Answer:
z=12/9 or 4/3 or 1 1/3
Step-by-step explanation:
1/3 needs to have a denominator of 9 so 3/9 because 3x3=9 and you have to multiply the numerator by 3 also
z-4/9-3/9=5/9
add -4/9 and -3/9 because you add two negative numbers
new equation
z-7/9=5/9
add 7/9 to 5/9
z=12/9 or 4/3 or 1 1/3

You meet with the financial aid office to discuss your costs for attending MGA next semester. Tuition is $113.67 per credit hour, and fees are a flat cost of $660. You have a grant of $350 and a scholarship of $400. If you are taking 15 credit hours, what amount will you need to pay for your classes next semester?
Answer:
$1615.05
Step-by-step explanation:
First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.
Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.
Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.
113.67h + 660 = 350 + 400 + x
113.67(15) + 660 = 350 + 400 + x
1705.05 + 660 = 750 + x
2365.05 = 750 + x
1615.05 = x

k = [tex]\frac{11}{4}[/tex]

A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16t2. Assume the distance from the top of the cliff to the water below is 96 ft.
A) When will the rock strike the water?
B) Make a table of average velocities and approximate the velocity at which the rock strikes the water.
Answer:
A) 2.45 seconds
B)[tex]\begin{center}\begin{tabular}{ c c}\bold{Average Velocity} & \bold{Velocity at strike of water} \\ 39.18 & 78.4 \\ \end{tabular}\end{center}[/tex]
Step-by-step explanation:
Distance [tex]s[/tex] (in feet) from the top of cliff after [tex]t[/tex] seconds when a rock is dropped off the edge of a cliff is given as:
[tex]s(t)=16t^2[/tex]
Distance from the top of cliff to water = 96 ft
To find:
A) When will the rock strike the water
i.e. The time taken by the rock to travel the distance of 96 ft.
B) Table of Average Velocity and approximate velocity at which the rock strikes the water ?
Solution:
A) Given that distance traveled = 96 ft
To find the value of [tex]t[/tex]
Putting the value of [tex]s[/tex] in formula: [tex]s(t)=16t^2[/tex] to find [tex]t[/tex]:
[tex]96 = 16t^2\\\Rightarrow t^2=6\\\Rightarrow \bold{t = 2.45\ sec}[/tex]
B) The velocity at which the rock hits the water:
We need to differentiate [tex]s(t)[/tex] w.r.to [tex]t[/tex] in order to find the velocity at any instant.
[tex]s'(t) =\dfrac{d}{dt}s(t) = \dfrac{d}{dt}(16t^2)\\\Rightarrow v = 2\times 16t^{(2-1)}\\\Rightarrow v = 32t[/tex]
The time taken to reach the water is 2.45 seconds.
Putting [tex]t[/tex] = 2.45 seconds to find the velocity:
[tex]v = 32\times 2.45 = 78.4\ ft/sec[/tex]
Average velocity is given as total distance traveled and total time taken.
[tex]\text{Average Velocity = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]
[tex]\text{Average Velocity = }\dfrac{96}{2.45}\\\text{Average Velocity = 39.18\ ft/s}[/tex]
[tex]\begin{center}\begin{tabular}{ c c}\bold{Average Velocity} & \bold{Velocity at strike of water} \\ 39.18 & 78.4 \\ \end{tabular}\end{center}[/tex]

Give two different ways to write each expression in words
Answer:
Sometimes in math we describe an expression with a phrase. For example, the phrase
"222 more than 555"
can be written as the expression
2 + 52+52, plus, 5.
Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable).
For example,
"333 more than xxx"
can be written as the algebraic expression
x+ 3x+3x, plus, 3.
But why? Why use math if we can describe things in words? One of the many reasons is that math is more precise and easier to work with than words are. This is a question you should keep thinking about as we dig deeper into algebra.

3n-5=8(6+5n) addition property of equality
Answer:
exact form: n=-53/37
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable.
The properties used:
a) Distributive Property.
b) Combining Like Terms.
c) Division Property of Equality.
Given is an equation 3n-5 = 8(6+5n), we need to solve it by using Property of Equality.
Let's solve the equation step by step:
3n - 5 = -8(6 + 5n)
First, we will distribute the -8 to the terms inside the parentheses:
3n - 5 = -48 - 40n
Next, we can simplify the equation by combining like terms:
3n + 40n = -48 + 5
43n = -43
Now, to isolate n, we will divide both sides of the equation by 43:
(43n)/43 = (-43)/43
n = -1
The solution to the equation is n = -1.

if a cubic container has a side length of 50.0cm, what is the volume in liter?
Answer:
The answer is
125 litresStep-by-step explanation:
To find the volume in liter we must first find the volume in cm³
Since the container is cubic
Volume = l³
where l is the length of one side
From the question
l = 50.0 cm
Volume = 50³
= 125000 cm³
Next we use the conversion
1cm³ = 0.001 L
If 1 cm³ = 0.001 L
Then 125,000 cm³ = 125,000 × 0.001 L
We have the final answer as
125 litresHope this helps you
Using the volume of a cube, and conversion of units, it is found that the volume of the cube is of 125 liters.
---------------------
The volume of a cube of side s is given by:
[tex]V = s^3[/tex]
---------------------
Side length of 50cm means that [tex]s = 50[/tex].Thus, the volume, in cubic centimetres, is given by:
[tex]V = 50^3 = 125000[/tex]
---------------------
To convert the volume from cubic centimetres to liters, it is divided by 1000.Then:
[tex]\frac{125000}{1000} = 125[/tex]
The volume of the cube is of 125 liters.

However, if he groups the pigs three to a pen, there no pigs left. What is the greatest number of pigs that Farmer Hank could have on his farm?
Answer:
the answer is 99
Step-by-step explanation:
A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? Choose the equation to match the situation
Answer:
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L - 4.3L= 5.7L
Step-by-step explanation:
From the given information:
Let consider x to be the of volume 40% solution
therefore the volume of 5% is said to be:
10 L= 40% solution volume + 5% solution volume
10 L= (x + 5%) solution volume
making 5% solution volume the subject; we have
5% solution volume= 10 L - x
To estimate the value of the volume, we now have:
Volume of 20% × Concentration of 20%= (Volume of 40% × concentration40%) + (Volume of 5% × Concentration of 5% )
∴
10L × 20%= (x) L × 35% + 10 L × 5%
(x) L × 35 = 10L × 20 - 10 L × 5 = 10 L × 15
[tex]x L = 10L \times \dfrac{15}{35}[/tex]
x = 4.28 L
x [tex]\simeq[/tex] 4.3L
∴
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L - 4.3L= 5.7L
What is the value of x in this equation? 5x − 2(2x − 1) = 6
Answer:
x=4
Step-by-step explanation:
first you would factor the -2(2x-1). -2x2x= -4x, -2x-1= 2
the equation would then be 5x-4x+2=6
add the x's together which turns the equation to 1x+2=6
minus 2 from both sides of the equation which gives you x=4
The required value of x would be 4 in the given equation 5x − 2(2x − 1) = 6.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have to determine the value of x in the equation
Given that the equations as :
⇒ 5x − 2(2x − 1) = 6
Open the parentheses and apply the multiplicative property,
⇒ 5x - 4x + 2 = 6
Apply the subtraction operation in the terms of x
⇒ x + 2 = 6
⇒ x = 6 - 2
⇒ x = 4
Therefore, the required value of x would be 4 in the equation
