Answer:
n = 3.8
Step-by-step explanation:
First, we would distribute 0.3 with n and 1.5.
0.3(n - 5) = 0.4 - 0.2n → 0.3n - 1.5 = 0.4 - 0.2n
Next, we can move the number with the variable to one side.
0.2n + 0.3n - 1.5 = 0.4 - 0.2n + 0.2n → 0.2n + 0.3n - 1.5 = 0.4
(Because we added 0.2n to the negative 0.2n on the right side, it cancels it out)
We can also move 1.5 to the right side of the equation as well.
0.2n + 0.3n - 1.5 + 1.5 = 0.4 + 1.5 → 0.2n + 0.3n = 0.4 + 1.5
Then, we combine like terms
0.2n + 0.3n = 0.5n & 0.4 + 1.5 = 1.9 → 0.5n = 1.9
Finally, we divide both sides by 0.5.
n = 3.8

A shipping container will be used to transport several 120-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 25500
kilograms. Other shipments weighing 14500 kilograms have already been loaded into
the container. What is the greatest number of 120-kilogram crates that can be loaded
into the shipping container?
Answer: 91 crate
Step-by-step explanation:
weight preloaded=
14500
weight per crate=
120
weight capacity=
25500
Method 1 (Unwinding):
weight of all crates=
weight capacity−weight preloaded
=
=
25500−14500
=
11000
number of crates=
weight per crate
weight of all crates
=
=
120
11000
=
91.666666...
Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.
Method 2 (Algebra):
c= number of crates
The greatest weight means less than 25500 kilograms can also be loaded into the container, so we will use the \leq≤ ("less than or equal to") symbol:
120c+14500≤
25500
−14500=
−14500
\color{red}{120}c\leq
120c≤
11000
120
11000
Divide both sides by 120
c ≤ 91.666666...
Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.
Two expressions are shown below.
Expression 1: 0.25x - 12
Expression 2: 18- 0.55x
For which value of x will the two expressions have the same value?
A
-100
B
-20
С C
7.5
37.5
Answer:
0.25x -12= 18- 0.55x (subtract 0.25x from both sides)
-12= 18 -0.80x (subtract 18 from both sides)
-30= -0.80x (divide each side by -0.80)
x= 37.5 (this is your answer)
The value of x in which the two expressions have the same value is 37.5
Here,
Given that;
Two expressions are,
Expression 1 : 0.25x - 12
Expression 2: 18- 0.55x
We have to find the value of x.
What is Mathematical expression?
A sentence with a minimum of two numbers or variables and at least one math operation is present, is called Mathematical expression.
Now,
The value of x will be find after equating both expressions as;
0.25x - 12 = 18 - 0.55x
Subtract 0.25x from both sides, we get;
- 12 = 18 - 0.80x
Subtract 18 from both side, we get;
- 30 = - 0.80x
Divide each side by -0.80, we get;
x= 37.5
Hence, The value of x in which the two expressions have the same value is 37.5

[tex]y = -3x + 16[/tex]
Step-by-step explanation:
Given
[tex]Point = (6, -2)[/tex]
[tex]m = -3[/tex]
Required
Is the given info enough to find the equation?
Yes, it is enough and the proof is as follows:
And equation is solved using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex](x_1,y_1) = (6,-2)[/tex]
[tex]m = -3[/tex]
Substitute these values in [tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - (-2) = -3(x - 6)[/tex]
[tex]y +2 = -3(x - 6)[/tex]
Open bracket
[tex]y +2 = -3x + 18[/tex]
Make y the subject
[tex]y = -3x + 18-2[/tex]
[tex]y = -3x + 16[/tex]
From the above, one can see that the given info is enough
Dawn bought 3 video games and 9 DVDs for $75. Jerry bought
5 video games and 10 DVDs for $25 more than Dawn. How
much did each DVD cost?
Answer:
$5
Step-by-step explanation:
We can solve this using a system of linear equations. The equations are written like this:
3v + 9d = 75
5v + 10d = 100 (25 more than Dawn's total is 100)
V represents video games and d represents DVDs.
Let's isolate a variable, I'm going to isolate v in the first equation:
3v = -9d + 75
v = -3d + 25
Now that we isolated v we can plug it in to the second equation:
5(-3d + 25) + 10d = 100
-15d + 125 + 10d = 100
-5d + 125 = 100
-5d = -25
d = 5
Therefore, each DVD cost $5.
Check:
3v + 9(5) = 75
3v + 45 = 75
3v = 30
v = 10
5(10) + 10(5) = 100
50 + 50 = 100
100 = 100
I hope this helps!!

Answer:
90%
Step-by-step explanation:
1. We assume, that the number 5400 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 5400, so we can write it down as 100%=5400.
4. We know, that x% equals 6000 of the output value, so we can write it down as x%=6000.
5. Now we have two simple equations:
1) 100%=5400
2) x%=6000
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=5400/6000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 6000 is what percent of 5400

The base of a 15 foot ladder is 6 feet from a building, if the ladder reaches the flat roof, How tall is the building?
Answer:
13.7 feet
Step-by-step explanation:
The ladder and the building will form a right triangle with the ladder's length is hypotenuse
so if a is the height of the building
c^2 = a^2 + b^2
(15)^2 = a^2 + (6)^2
225 = a^2 + 36
a^2 = 225 - 36 = 189
a = √(189 = 13.7

State A contains the largest state population of Native Americans. This population is three times the Native American
population of State B. If the total of these two populations is 376 thousand find the Native American population in
each of these two states.
The Native American population in state A and B is 282,000 and 94,000 respectively.
Here, we are given that State A's population of Native Americans is three times the Native American population of State B.
Let the Native American population in state B be x
Thus, the Native American population in state A will be 3x
Total Native American population in state A and B = 376,000
Thus, we can get the following equation-
x + 3x = 376,000
4x = 376,000
x = 376,000/ 4
x = 94,000
⇒ 3x = 3 × 94,000
3x = 282,000
Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.

Use symmetry to evaluate the following integral.
[tex]\int\limits^4_{-4} {\frac{x^3+3x}{x^4+5} } \, dx[/tex]
The integrand is odd.
[tex]f(x) = \dfrac{x^3 + 4x}{x^4 + 5} \implies f(-x) = \dfrac{(-x)^3 + 4(-x)}{(-x)^4 + 5} = \dfrac{-x^3-4}{x^4+5} = -f(x)[/tex]
The integral of an odd function over a symmetric interval is zero, so
[tex]\displaystyle \int_{-4}^4 \frac{x^3+3x}{x^4+5} \, dx = 0[/tex]
This is because
[tex]\displaystyle \int_{-a}^a f(x) \, dx = \int_{-a}^0 f(x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = -\int_0^{-a} f(x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = \int_0^{-a} f(-x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = -\int_0^a f(x) \, dx + \int_0^a f(x) \, dx = 0[/tex]
where we substitute [tex]x\mapsto-x[/tex] in the second-to-last equality.
