The solution to the equation[tex]\dfrac{3}{7}(x+3)+5=3x+2[/tex] when "x" is an unknown variable is  [tex]\dfrac{5}{3} .[/tex]

Two algebraic expressions separated by an equal symbol between them and with the same value are called equations.

Example = 2x +4 = 12

here, 4 and 12 are constants and x is variable.

To solve the equation[tex]\dfrac{3}{7}(x+3)+5=3x+2[/tex] we can follow these steps:

Multiply \dfrac{3}{7} into the brackets or inside the parentheses

[tex][\dfrac{3}{7}x + \dfrac{3}{7}\times3] + 5 = 3x + 2[/tex]

[tex]\dfrac{3}{7}x +\dfrac {9}{7} + 5 = 3x + 2[/tex]

On solving we get,

[tex]\dfrac{3x+9}{7} = 3x +2-5[/tex]

[tex]\dfrac{3x+9}{7} = 3x -3[/tex]

On cross multiplication we get,

[tex]{3x+9} = 7(3x -3)[/tex]

Opening the parenthesis we get

[tex]{3x+9} = (21x -21)[/tex]

Taking the variables to one side and constants on the right side we get,

[tex]{9+21} = (21x -3x)[/tex]

On further solving we get,

30 = 18 x

Simplify and solve for x:

Divide both sides by 18, and we get

[tex]\dfrac{30}{18} = x[/tex]

Now, in standard form

[tex]\dfrac{5}{3} = x[/tex]

In decimals, we get 1.66666.

Therefore, the solution to the equation [tex]\dfrac{3}{7}(x+3)+5=3x+2[/tex] is [tex]\dfrac{5}{3}[/tex].

The explicit formula for the geometric sequence 12, -36, 108, -324, ... is f(n) = 12 * (-3)^(n-1), where 'n' is the term number.

The series provided is a geometric series. In a geometric series, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio, denoted by 'r'. In our given series 12, -36, 108, -324, ..., you can determine that the common ratio (r) is -3. Now, using the formula for a geometric sequence given by f(n) = a * r^(n-1), where 'a' is the first term (12 in this case) and 'n' is the term number, we can write the explicit formula as

f(n) = 12 * (-3)^(n-1).

Answer:

Is there a x somewhere or is that litteraly how the equation is?

If so, -7 multiplied by 2 is -14,

-1 times -7 is 7,

add it together and you get

-7=28,

you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0

which would make the solution false since both sides are not the same

The correct answer is [tex]\(\frac{17}{20} \times 100\%\)[/tex].

To find the percentage of students who passed the quiz, we need to divide the number of students who passed by the total number of students, and then multiply by 100 to convert the fraction to a percentage.

 Given that 17 students passed out of 20, the calculation is as follows:

[tex]\[ \text{Percentage of students who passed} = \left( \frac{\text{Number of students who passed}}{\text{Total number of students}} \right) \times 100\% \][/tex]

[tex]\[ \text{Percentage of students who passed} = \left( \frac{17}{20} \right) \times 100\% \][/tex]

 This fraction can be simplified to a decimal or a mixed number if necessary, but it is most accurate and precise in its fractional form as given above. To convert it to a decimal, one would divide 17 by 20 and then multiply by 100, which would yield 85%. Thus, 85% of the students passed the quiz.

Step-by-step explanation:

The graph of y= -4×+7 is​ a straight line with slope -4 and y-intercept 7.  Please do not use × to represent the independent variable; use x instead.  × represents multiplication.

To graph this function, first plot the y-intercept, b, which is (0, 7).

Next, starting with your pencil point at (0, 7), move the point 1 unit to the right and plot another point (which will be (1, 7) ).  Now move your pencil point 4 units down and plot your third point, which will be (1, 3).

Finally, draw a straight line thru the first and third points, that is, thru (0, 7) and (1, 3).  Notice how this line has the slope -4 and the y-intercept (0, 7).

Step-by-step explanation:

Look at where the numbers are placed, in regards to the decimal point.

If a number is 1 place before a decimal point (For example 5.0) it is in the ones place.

If a number is 1 place after a decimal point (For example 0.1) It is in the tenths place.

Answer: Side one is 7 3/8

Side two is 8 2/8

Side three is 3 3/8

Perimeter is 19

Step-by-step explanation:

The first side is    a+3 1/4

the second side is  2a

The third side is   7 1/2-a

Plug 4 1/8 in for a

First side   4 1/8+3 1/4

Find the common denomnator which is 8

4 1/8+3 2/8

7 3/8

First side is 7 3/8

Second side  2(4 1/8)=4 1/8 +4 1/8= 8 2/8

Third side is 7 1/2-4 1/8

Find the common denominator which is 8

7 4/8-4 1/8= 3 3/8

Third side is 3 3/8

The perimeter is adding all the three sides together

7 3/8+8 2/8+ 3 3/8=18 8/8

Reduce 18 8/8=18 +1=19

Answer:

Perimeter = 19 units

Step-by-step explanation:

Given a = 4 1/8

[tex]Side1 = a + 3\frac{1}{4}\\Side2 = 2a\\Side3 = 7\frac{1}{2}-a[/tex]

The next step is substituting the a value in the expressions:

[tex]Side1 =  4\frac{1}{8}+ 3\frac{1}{4}\\Side2 = 2*(4\frac{1}{8})\\Side3 = 7\frac{1}{2}-4\frac{1}{8}[/tex]

Then, fractions with different denominators must be converted to the same denominator. Also, the multiplication of a whole number by a mixed number can be done by using distributive law:

[tex]Side1 =  4\frac{1}{8}+ 3\frac{2}{8}\\Side2 = 8\frac{2}{8}\\Side3 = 7\frac{4}{8}-4\frac{1}{8}[/tex]

[tex]Side1 =  7\frac{3}{8}\\Side2 = 8\frac{1}{4}\\Side3 = 3\frac{3}{8}[/tex]

Now, the perimeter is the sum of all the sides. Therefore, the perimeter is:

[tex]Perimeter =  7\frac{3}{8} + 8\frac{1}{4} + 3\frac{3}{8}[/tex]

Which is 19 units.

Step-by-step explanation:

We can multiply powers with the same base

x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6

Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.

The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.

Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.

These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Answer:  -1 < x < 8

                x ≠ 2

Step-by-step explanation:

Isolate x in the middle.  Perform operations to all 3 sides.

-6 < 2x - 4 < 12

+4        +4   +4

-2 < 2x       < 16

÷2    ÷2         ÷2

**************************************************************************

Isolate x.  Solve each inequality separately. Remember to flip the sign when dividing by a negative.

       4x ≤ 12       and       -7x ≤ 21

      ÷4    ÷4                 ÷-7     ÷-7

        x ≤ 3         and         x ≥  3

Since it is an "and" statement, x is the intersection of both inequalities.

When is x ≤ 3 and ≥ 3?    when x = 3

       x > 2          or              x <   2

Since it is an "or" statement, x is the union of both inequalities.

When we combine the inequalities, x is every value except 2.

Monthly payment is the principal and interest payment for each year for $1000 financed. he payment of the mortgage is $4639.75

The period for which the mortgage offered is 30 years.

Step-by-step explanation:

18+t<26

alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.

She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.

She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)

so let me put it like this:

18+1<26 yes because 18+1=19 which is less than 26

18+2<26 yes because 18+2=20 which is less than 26

18+3<26 yes because 18+3=21 which is less than 26

18+4<26 yes because 18+4=22 which is less than 26

18+5<26 yes because 18+5=23 which is less than 26

18+6<26 yes because 18+6=24 which is less than 26

18+7<26 yes because 18+7=25 which is less than 26

18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)
