Answer:

a = 17 / 11

Step-by-step explanation:

or, a - 2 = 3(3 + 6a)

or, a - 2 = 9 + 18a

or, - 2 - 9 = 18a - a

or, -11 = 17a

or, a = 17 / 11

Answer:

250 Hamburgers

Step-by-step explanation:

575 is total

Hamburger is x

Cheesburgers is (x-75) as it is 75 less than the number of hamburgers

x + (x-75) = 575

2x -75 = 575

2x = 500

x = 250

Jen 's drawing shows that the lines are parallel in fact they are not parallel !  Since their slopes are not equal !

[tex]\displaystyle \left \{ {{y=2x+3} \atop {-y=2x+1}\ \ |\cdot (-1) } \right. => \left \{ {{y=\boldsymbol {2}x+3} \atop {y=\boldsymbol {-2}x-1}} \right. => -2\neq 2[/tex]

They will intersect at point A with coordinates  :

Answer:

Tn=a+(n−1)d, where a= First term, d= Difference between terms ... (2)

Equating (1) and (2)

6n+5=a+(n−1)d

6n+5=a+nd−d ..... (3)

Equating n terms:6n=nd

d=6 ...... (4)

Substituting (4) in (3)

6n+5=a+6n−6

5=a−6

a=11 ..... (5)

Now

Sn=2n(2a+(n−1)d)

Sn=2n(a+Tn) ....... (6)

Substituting (1) and (5) in (6)

Sn=2n(11+6n+5) 

Sn=2n(16+6n) 

Sn=n(8+3n)

Answer:

a) 0.35

Step-by-step explanation:

The manager of a food court estimated that he needed 7 pretzels for every 20 people who attend that hockey game. This means that  20 people need/require to have 7 pretzels. 20 people= 7 pretzels.

(13/3) / (-2/1) = (13/3) / (-2) = - 13 / (3 • 2) = -13/6

21.6666666667 can be expressed as the fraction 21 2/3 or 65/3.

13/3 divided by -2/1 is equal to -13/6.

Given that we need to convert 21.6666666667 can be expressed as the fraction and 13/3 divided by -2/1 as a fraction.

To convert the decimal number 2.16666666667 to a fraction, we can multiply both the numerator and denominator by a power of 10 to eliminate the decimal point.

Since there is only one digit after the decimal point, we can multiply by 10.

2.16666666667 x 10 = 21.666666667

Now we have the number 21.666666667 as a whole number. Since there are three repeating digits (6), we can represent them as a fraction over 9 (since 9 is the largest power of 10 that is one less than the number of repeating digits).

21.666666667 = 21 + 0.666666667

= 21 + 6/9

Simplifying the fraction 6/9, we can divide both the numerator and denominator by their greatest common divisor, which is 3.

6/9 = (6 ÷ 3) / (9 ÷ 3)

= 2/3

Therefore, 2.16666666667 can be expressed as the fraction 21 2/3 or 65/3.

For the division problem (13/3) ÷ (-2/1), we can convert it into a multiplication problem by multiplying the first fraction by the reciprocal of the second fraction.

(13/3) ÷ (-2/1) = (13/3) x (1/-2)

Multiplying the numerators and denominators, we get:

(13 x 1) / (3 x -2) = 13 / -6

Therefore, 13/3 divided by -2/1 is equal to -13/6.

Answer:

y = -5/3x + 19/3

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - 8 / 5 - (-1)

-10/6

= -5/3

y = -5/3x + b

8 = -5/3(-1) + b

8 = 5/3 + b

Answer:

x×2+13=5

Step-by-step explanation:

We use x as the unknown number, and we just put what's in the word problem! The answer is in the question.

Equation Set-Up

x×2+13=5

Remember order of operations! (PEMDAS)

Then you solve the equation.

Because of PEMDAS, we know that multiplication is the first thing we have to do.

x×2=2x

So now, our equation looks like this.

2x+13=5

We subtract 13 from the +13 to cancel it out, but that means that we also have to subtract 13 from the 5 on the other side. We are now left with this.

2x=-8

Then, we divide -8 by 2, which gives us...

x=-4

Pablo's number is -4.

I hope I helped! Have a great day.

Answer: The equation has infinitely many solutions.

Step-by-step explanation:

With George's end result of 3=3, you can assume that the equation is set up in such a way that no matter what you plug in, you will get the same number on both sides of the equals sign, which means the solution is valid. Therefore this means that there are an infinite number of solutions.
