Charlene's age is 4 less than 3 times Mary's age, x.
Which expression represents Charlene's age?
O A 3X - 4
OB. 3(x-4)
O C. 4X-3
OD. 4 - 3x
The solution is Option A
The equation of Charlene's age is 3x - 4
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let Charlene's age be C
The age of Mary is = x
Now , the equation is
Charlene's age is 4 less than 3 times Mary's age
Substituting the values in the equation , we get
C = 3 x ( Mary's age ) - 4
On simplifying the equation , we get
C = 3x - 4 be equation (1)
Therefore , the value of C is 3x - 4
Hence , the age of Charlene's age is 3x - 4

HELP (BRAINLIEST ANSWER IF RIGHT)...In a certain Algebra 2 class of 30 students, 7 of them play basketball and 11 of them play baseball. There are 5 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
13 / 30
Step-by-step explanation:
The probability an be represented by the number of desirable outcomes over the total outcomes. We know the total is 30 since there are 30 students to be chose from. Now, we need to find the number of students who play basketball and baseball. We can add the two values we are given:
7 + 11 = 18 students
BUT.... we are over-counting the students who play both. We need to subtract those 5 students, since the are counted twice, and that way, they will only be counted once:
18 - 5 = 13 students
Using the formula for probability at the top, we get:
13 / 30

Researchers for a textile company carried out an experiment comparing the longevity of two new fabric blends.
They carried out a series of usage tests, known as double rubs, on 100 pieces of each type of material. These scales are used for this type of testing.
Fabric Grade Number of Double Rubs
(in thousands)
Heavy duty
Medium duty
Light duty
Delicate duty
After performing the tests on each fabric, researchers found that on average, fabric A lasted through 7,900 double rubs and fabric B lasted through 9,200 double rubs.
The marketing department wants to advertise that both fabrics are tested and approved for medium-duty use.
Which statements are true about this situation?
The sales department can refer to fabric A as a medium-duty fabric.
The sales department can refer to fabric B as a medium-duty fabric.
Fabric A is a more durable fabric because it has a lower double rub rating than fabric B.
Fabric B is a more durable fabric because it has a higher double rub rating than fabric A.
Neither fabric meets the requirements of a medium-duty fabric.
Fabric B is a more durable fabric because it has a higher double rub rating than fabric A.
We have given that,

Translate (-3, 1) to the right 1 unit.
Then reflect the result over the y-axis.
What are the coordinates of the final point?
OD
?
Answer:
(2,1)
Step-by-step explanation:
When we translate to the right, we are simply adding a value to the x axis value corresponding to the units of translation
We have the translation by 1 unit, so we are to add 1 to the value of the x-coordinate
Thus, we have this as ;
(-3 + 1, 1)
= (-2,1)
When we reflect a point (x,y) over the y-axis, its new coordinates become (-x,y)
Applying this to what we have above, the coordinate of the final point will be (2,1)

Answer:
- 7y +3 =-25
-7y=-25—3
-7y=-28
-7y÷-7= -28÷-7
y=4
Step-by-step explanation:
Take +3 to the side so that your variable and a constant is on their own sides. When a number goes over the equals sign the sign changes at becomes the inverse that's why l said - 3. You now calculate - 25—3 equals 28 then divide by 7 to find y and your y is 4.

Answer:
[tex]\mathrm{d. \csc \theta =\frac{5}{3}}[/tex]
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\cot\theta =\frac{4}{3}[/tex] as given in the problem, then [tex]\tan \theta =\frac{3}{4}[/tex], because [tex]\tan \theta =\frac{1}{\cot \theta}[/tex]. Therefore, the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].
The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse.
Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h) and since [tex]\sin \theta =\frac{1}{\csc \theta}[/tex], we have:
[tex]\csc \theta=\frac{1}{\sin \theta}=\frac{1}{\frac{3}{5}}=\boxed{\frac{5}{3}}[/tex]

The descriptions below outline different payment options for Ashley's dog-walking business. Use x to represent the number of days she walks a dog and y to represent her earnings. For each equation and graph, drag the situation that can be modeled by that relationship into the space in that row.
Answer:
Step-by-step explanation:
y = 2x - 2 (Linear)
Here, x = number of days
y = Total payment
Ashley paid $2 each day and gives $2 to her brother.
y = 2x²
This quadratic relation represents the total payment 'y' is twice as much as the number of days times itself.
y = 2ˣ
Exponential function represents that the total payment is twice as much as the number of days times itself.

Answer:
hahshdbdbdbd 950kejejd
Answer:
40 and 65 respectively
Step-by-step explanation:
let no. of P 5 be x
and p 10 be y
now
x + y = 105
or, x =105 - y....(!)
again
5x + 10y = 850
or , x =( 850 - 10y)÷5....(!!)
from equation (i ) and (ii)
105 - y = (850 - 10y ) ÷ 5
or, (105 - y)5 = 850 -10 y
or, 525 - 5y = 850 - 10y
or, 10y - 5y = 850 - 525
or, 5y = 325
or, y = 65
now,
x = 105 - 65
x = 40
hence ,
P5 = 40
p10 = 65
Please help! It’s saying the answer isn’t 1!!! It’s the last question please helppp!
Answer:
1 and -1
Step-by-step explanation:
The correct answer is 1. The square root of a (real) number is always taken to be the non-negative square root (this allows the square root operation to be a function).
However, if the question is saying it isn't 1, then it wants you to answer 1 and -1, because both square to 1. A better way to word the question would be "For which values of x is x^2 equal to 1?"
