Which could be a step used when solving the equation 5x+10=7.5x?
Answer:
Putting all the x's to one side.
Step-by-step explanation:
By doing this, you would get:
10 = 2.5x
so,
4 = x
Answer:
We subtract 5x from both sides
Step-by-step explanation:
Step 1: Subtract 5x from both sides
[tex]5x + 10 = 7.5x[/tex]
[tex]10 + 5x - 5x = 7.5x - 5x[/tex]
[tex]10 = 2.5x[/tex]
Step 2: Divide both sides by 2.5
[tex]\frac{10}{2.5} = \frac{2.5x}{2.5}[/tex]
[tex]4 = x[/tex]
Answer: We subtract 5x from both sides

Step-by-step explanation:
1.
that creates a right-angled triangle :
the string is the Hypotenuse (the baseline, which is the side opposite of the 90° angle).
the invisible "line" from the kite straight down to the ground is one leg. and we need that length.
and the invisible "line" on the ground between the point where Brian is standing, and the point, where the : line: coming down from the kite hits the ground, is the second leg.
the angle between both legs is 90°.
so, we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the associated angles are always opposite of each other.
in our case, the Hypotenuse (the string) is opposite of 90°.
and the angle opposite of the kite height line is the designated angle of elevation at the point, where Brian is standing : 70°.
so, we have here
65/sin(90) = height/sin(70)
height = 65×sin(70)/sin(90)
sin(90) = 1
height = 65×sin(70) = 61.08002035... m
2.
another right-angled triangle.
what is not clear to me : what does "distance from plane to building" mean ?
is it really the line of sight from the plane in the air to the building in the ground ? which is the Hypotenuse of that triangle.
or is it the ground distance (from the point where the height line hits the ground to the building) ? which is also the air distance (parallel line to the ground distance up in the air with the plane).
remember, the sum of all angles in a triangle is always 180°.
per law of sine we have
height/ sin(28) = line of sight / sin(90) =
= air (or ground) distance / sin(180-28-90)
1200/sin(28) = line of sight / 1 =
= air distance / sin(62)
line of sight (if that is what we need) =
= 1200/sin(28) = 2,556.065362... m
air distance = 1200×sin(62)/sin(28) = 2,256.871758... m
3.
another right-angled triangle.
the Hypotenuse is the line of sight from the point 12 ft away in the ground to the top of the pole.
the ground distance (12 ft) is one leg.
the pole (and its height) is the second leg.
so, we have our law of sine
height/sin(53) = line of sight / sin(90) =
= ground distance / sin(180-53-90)
we need the height, so
height/sin(53) = ground distance / sin(37)
height = 12×sin(53)/sin(37) = 15.92453786... ft

When Mai turned 21, she invested $2000 in an Individual Retirement Account (IRA) that has grown at a rate of 10% compounded annually. If the account continues to grow at that rate, what will be its value when Mai turns 25?
well, Mai is 21 today and when she's 25 is 4 years from now, so
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$2000\\ r=rate\to 10\%\to \frac{10}{100}\dotfill &0.10\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &4 \end{cases} \\\\\\ A=2000\left(1+\frac{0.10}{1}\right)^{1\cdot 4}\implies A=2000(1.1)^4\implies A=2928.2[/tex]

What are the values of a and b in the relative frequency table for the survey results? round answers to the nearest percent. a = 33%, b = 73% a = 68%, b = 43% a = 25%, b = 32% a = 33%, b = 43%
The values of a and b are 33% and 42.7% respectively.
Calculations and Parameters:Given:
The number of students that like blue uniform is only as 32,
The number of students that like gold uniform is only as 25,
The number of students that like blue and gold uniforms is 12
The number of students that like neither blue nor gold uniform as 6.
Then, the total number of students interviewed are 75 students.
The relative frequency of the students who like blue is 25, therefore,
25/75= 1/3= 0.33
= 33%
The relative frequency of the students that like blue but not gold is 32, therefore,
32/75= 0.427
=42.7%

What is the value of x?
To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Answer:
x = 30°
Step-by-step explanation:
As the angle of 85° measure and the angle of (3x-5)° are vertical opposite angles, the measure of both the angles will be equal so...
(3x-5)° = 85°
3x = 85 + 5
3x = 90
x = 90/3
x = 30
So x is 30°
Let's recheck.
3x-5
(3 × 30) - 5
90 - 5
85°
Hence, the value of x = 30°

List the factors
of 38.
Is this number
prime or
composite?
Answer:
Composite number
Step-by-step explanation:
Prime numbers are whole numbers that have 2 factors of 1 and itself.Composite numbers are whole numbers that have factors of more than two factors. They can also be found by multiplying two or more smaller numbers.Factors of 38:
1 * 38
2 * 19
1, 2, 19, 38
Therefore, 38 is not a prime, but rather a composite number.

Write a polynomial that represents the area of the figure below:
Answer:
2x²+2x+5
Step-by-step explanation:
Since the area of a square is a² (where a is the length of one of its sides) we'll have:
(x—1)(x—1)+(x+2)(x+2) = (x²—2x+1)+(x²+4x+4) = 2x²+2x+5
So write the answer as: 2, 2 and 5

What is the slope-intercept equation of the line that contains the points (0, 3) and (1, 1)?
Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )
m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 2x + 3 ← equation of line
