Solve the equation below for x.
3.25x = 8.125
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
Divide each side by 3.25
3.25x/3.25 = 8.125/3.25
x =2.5
Answer:
x = 2.5
Step-by-step explanation:
3.25x = 8.125
then divide both sides by 3.25 to get x on its own
x = 2.5

what is the domain please help i’ll mark brainliest
Answer:
In mathematics, the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. It is the set X in the notation f: X → Y, and is alternatively denoted as {\displaystyle \operatorname {dom} }.
Step-by-step explanation:
Formula
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Absolute value
As the domain of absolute value refers to the set of all possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range of absolute value is the set of possible output values, which are shown on the y-axis.
Notation
We can write the domain of f(x) in set builder notation as, {x | x ≥ 0}. If the domain of a function is all real numbers (i.e. there are no restrictions on x), you can simply state the domain as, 'all real numbers,' or use the symbol to represent all real numbers.
Rules
If a function contains a square root, set the equation inside the square root greater or equal to zero and solve. The resulting answer is the domain. If a function contains a fraction, set the denominator not equal to zero and solve. The resulting answer is the domain.

I’m sorry if doesn’t make sense but there’s the picture!!
Given:
Lines DE and AB intersect at point C.
[tex]m\angle ACE=(2x+2)^\circ[/tex]
[tex]m\angle ECB=(5x+3)^\circ[/tex]
To find:
The value of x.
Solution:
In the given figure it is clear that the angles [tex]\angle ACE[/tex] and [tex]\angle ECB[/tex] are lie on a straight line AB.
[tex]m\angle ACE+m\angle ECB=[/tex] [Linear pair]
[tex](2x+2)^\circ+(5x+3)^\circ=180^\circ[/tex]
[tex](7x+5)^\circ=180^\circ[/tex]
[tex]7x+5=180[/tex]
Subtract 5 from both sides.
[tex]7x=180-5[/tex]
[tex]7x=175[/tex]
Divide both sides by 7.
[tex]x=\dfrac{175}{7}[/tex]
[tex]x=25[/tex]
Therefore, the correct option is B.
Answer:
x = 25

Find the value of x.
Show work. please help
Answer:
x=7
Step-by-step explanation:
Since this is an isosceles triangle the two angles are equal.
3x+6 = 5x-8
Subtract 3x from each side
3x+6-3x = 5x-8-3x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 = 2x/2
7 = x
Answer:
x = 7
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).
3 x + 6 = 5 x - 8
Subtract 3 x from both side
3 x - 3 x + 6 = 5 x - 3 x - 8
6 = 2 x - 8
add 8 to each side
6 + 8 = 2 x - 8 + 8
14 = 2 x
Divide each side by 2
14 / 2 = 2 x / 2
7 = x
The expression -310 + 15m represents a submarine that began at a depth of 310 feet below sea level and ascended at a rate of 15 feet per minute. What was the depth of the submarine after 8 minutes?
Answer:
190 feet below sea level
Step-by-step explanation:
d = -310 + 15m
d = -310 + 15(8)
d = -310 + 120
d = -190

= (-4*1)/(5*2)
= -4/10
= -2/2 * 2/5
-2/5
Hence the required values is -2/5

Turner's scores for nine video games are 140, 180, 200, 170, 180, 150, 160, 130, and 121. The mean, median, and mode of his scores are given below.
mean = 159
median = 160
mode = 180
Which value gives Turner's game average?
Answer:
The mean gives Turner’s game average.
Step-by-step explanation:
The median describes the number in the middle from lowest to greatest. The mode describes the number that appears the most. The mean describes the average of the data set.

Complementary angles
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
Answer:
complementary
Step-by-step explanation:
The angles are part of a right angle as shown by the square.
Complementary angles are angles that add up to 90˚
since x-15 and 2x are parts of the right angle, they add up to 90
There were 400 students in attendance. 51% are boys. How many are boys (show your work)
Answer:
204 out of 400 students are boys; 204
Step-by-step explanation:

100x = 51 x 400
100x = 20400
100x/100 = 20400/100

Answer:
Top left Equation: [tex]\frac{2}{3} + (- 2 \frac{1}{3} ) = - 1 \frac{2}{3}[/tex]
Step-by-step explanation:
You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
And 2/3 + (-2 1/3) = -1 2/3

Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)
x = 46.7°

In a straight line, like the one presented before you, there is 180 degrees. So that means 115 degrees + x is gonna equal 180.
So that means, x is gonna be 180 - 115. So x is 65 degrees
