Answer:

B. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −3.

Statement B is true. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −3.

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

Equation 1;

-2x=14

Equation2;

6x=-42

Multiply equation 2 on both sides by -3.

-2x=14

-2x×3=14×3

6x= - 42

Because the second equation can be found by multiplying both sides of the first equation by 3, the equations have the same solution.

Hence, statement B is true

let x be the price before the discount

If you get 12% off, then you only pay the remaining 88% (since 88%+12% = 100%). This means if you take 88% of the original price (x), then you get the final price (132)

In terms of an equation, we have,

88% of (original price) = final price

(88/100)*(x) = 132

0.88*x = 132

0.88*x/0.88 = 132/0.88 <--- divided both sides by 0.88

x = 150

--------------------------------------------

Answer: The price without the discount is $150

The total cost for 53 people attending the school banquet is $1,665.

Given the parameter:

The cost of a school banquet is expressed as:

$75 + 30n, as n is the number of people attending.

To determine the cost for 53 people attending the school banquet, you can plug the value of n (which is 53) into the given cost function:

Cost = $75 + 30n

Plug in n = 53

Cost = $75 + 30( 53 )

Cost = $75 + 1590

Cost = $1,665

Therefore, the total cost will be $1,665.

Here domain is all real x.

Range is :

{y ∈ R : y ≤ -5 or y ≥ 3}

In interval form:

Solve for x .

Square both the side

9x² + 6x + 1 =  4 + x² - 4x

Since an integer is any whole (not fractional) number on the number line, all you have to do is move to the left however many units you're subtracting by from the point given. Say the problem is 3 - 7. This means we start at 3, and move to the left 7 units, which lands us at -4. However, if we had a problem like 12 - (- 2), the two negatives would cancel out, meaning we will move to the right 2 units on the number line, or 12 + 2, which is 14. Some other examples are:

-12 - 4, (you should get -16)

3 - 8, ( you should get -5)

16 - (- 3), ( you should get 19)

I hope these tips helped you out! I know that when I first had to subtract integers, using a number line really helped me out. Eventually, it'll just be a natural thing. :D

at this rate, he will have attempted 27 passes. we can find this by setting the problem up into a proportion: 10/18=15/?

once we solve the proportion, we get that he attempted 27 passes in order to complete 15

Final answer:

To solve for the number of passes the quarterback will attempt to complete 15 passes, we set up a proportion based on the completed 10 out of 18 passes. By cross-multiplying and solving for the unknown, we find that the quarterback would need to attempt 27 passes.

Explanation:

The question is asking us to find out how many passes the Rams' quarterback will attempt if he is to complete 15 passes, given that he completed 10 out of 18 passes in his last game. This is a proportion problem in mathematics where we set up a ratio of completed passes to attempted passes and solve for the unknown.

We know the quarterback completed 10 passes out of 18 attempts, so the ratio of completed to attempted passes is 10/18. If we want the quarterback to complete 15 passes, we can set up the proportion as:

10/18 = 15/x

where x represents the number of passes that the quarterback will attempt. To solve for x, we cross-multiply:

10(x) = 18(15)

x = (18(15))/10

x = 27

Therefore, the quarterback will have to attempt 27 passes to complete 15 passes at the same completion rate.

Answer: 68

Step-by-step explanation:

LM   +    MN     =   LN

x + 7  + 3x + 20 = 6x - 5

            4x + 27 = 6x - 5

           -4x         -4x      

                    27 = 2x - 5

                     +5        +5

                    32  = 2x

                    ÷2   ÷2    

                     16 = x

MN: 3x + 20

       3(16) + 20

         48   + 20

               68

This question is based on a principle in Mathematics called the Midpoint of a linelineline

Based on this question, the line = LNLN

To solve this question, we have the expression

LM + MN = LN

Step 1

We solve for x

Given that: LN= 6x-5 , LM= x + 7 , and MN= 3x + 20

Hence,

x + 7 + 3x + 20 = 6x - 5

Collect like terms

7 + 20 + 5 =6x - x - 3x

32 = 2x

Divide both sides by the coefficient of x = 2

32/2 = 2x/2

x = 16

The value of x = 16

Step 2

Find MN

Given that : MN= 3x + 20 and x = 16

We substitute 16 for x in MN

MN = 3(16) + 20

MN = 48 + 20

MN = 68

Therefore, the value of MN is 68.

Answer:

every 20 days

Step-by-step explanation:

The minute hand is like an eight inch radius of a circle, whose circumference would equal 2 * PI * 8 = 50.265 inches.  By moving to 8 o'clock, it travels 2/3 of the circumference or 50.265 * 2/3 = 33.510 inches

if the minute hand is 8 inches long, it shows the radius of the circle of the clock.

thus, the circumference of the circle (boundary)= 2πr

= 2X 3.14 X 8    ( wherein, r= radius= 8; π= 22/7 or 3.14)

= 50.27 inches.

The length between each two consecutive no.s on the clock = 50.27/12 = 4.19

Thus, the length moved n=by the tip of the minute hand= 4.19X8

= 33.44 inches

Answer:

the answer is 3x-5

Step-by-step explanation:

break the expression in to groups

3x^2 + 4x -15 =  (3x^2 -5x) + (9x-15)

factor out x from 3x^2 -5x: x(3x-5)

factor out 3 from 9x-15: 3(3x-5)

=x(3x-5) +3(3x-5)

factor out common terms

(x+3) (3x-5)

=((x+3) (3x-5)) / (x+3)

cancel the common factor x+3

=3x-5

The quotient for the expression is equal to 3x-5.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Break the expression into groups

3x² + 4x -15 =  (3x² -5x) + (9x-15)

Factor out x from 3x^2 -5x: x(3x-5)

Factor out 3 from 9x-15: 3(3x-5)

=x(3x-5) +3(3x-5)

Factor out common terms

(x+3) (3x-5)

=((x+3) (3x-5)) / (x+3)

Cancel the common factor x+3

=3x-5

Therefore, the quotient for the expression is equal to 3x-5.

To solve the inequality 2x+4≥24, subtract 4 from both sides, simplify the expression, divide both sides by 2, and simplify again. The solution is x≥10.

Let's solve the inequality 2x+4≥24. The first step is to isolate the term with x on one side. We can do this by subtracting 4 from both sides, which results in 2x ≥ 20. Next, we want to solve for x, so we divide both sides by 2: x ≥ 10. This means that x is greater than or equal to 10. lets solve step-by-step.

To solve the inequality 2x+4≥24, we need to isolate the variable x.

Step 1: Subtract 4 from both sides of the inequality: 2x+4-4≥24-4

Step 2: Simplify: 2x≥20

Step 3: Divide both sides of the inequality by 2: 2x/2≥20/2

Step 4: Simplify: x≥10

The solution to the inequality is x≥10. This means that any value of x that is greater than or equal to 10 satisfies the inequality.

The given pentagon can be divided into two figures : a triangle and rectangle as shown in figure.

Let us find area of each figure separately.

Triangle:

Area of triangle is given by:

[tex]A=\frac{1}{2}*b*h[/tex]

where b=base and h=height

Height of triangle :

h=(3x+5)-(2x+1)

h=x+4

Base = 2x-2

[tex]A=\frac{1}{2}*(x+4)(2x-2)[/tex]

Area of triangle= (x-1)(x+4) = x²+3x-4

Area of rectangle:

Area of rectangle is given by:

A=l*b

[tex]A=(2x-2)(2x+1)[/tex]

Area of rectangle = 4x²-2x-2

Area of pentagon = Area of triangle + Area of rectangle

Area of pentagon = x²+3x-4 + 4x²-2x-2

Area of pentagon = 5x²+x-6

If area of pentagon is 42 cm², then solving for x,

[tex]42=5x^{2}+x-6[/tex]

[tex]5x^{2}+x-48=0[/tex]

Factorising to get x,

x=-3.2 and x=3

If we take x as negative the side will be negative, so we neglect x=-3.2

So x=3 is the answer.
