Answer:

x = -46.5

x + 1 = -45.5

Step-by-step explanation:

x + x + 1 = -92

2x + 1 = -92

      -1       -1

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

   2x = -93

   ----     ----

    2        2

   x = -46.5

x + 1

(-46.5) + 1

-45.5

Answer:

No solution

Step-by-step explanation:

We can set up an equation where x is the integer and x+1 is the next one

x+x+1=-92

2x+1=-92

2x/2=-93/2

x=-46.5

-46.5+1=-45.5

The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.

Jacob is 4 years old and his mother is 40 years old.

Step-by-step explanation:

Part 1: The linear equations are  and

Part 2: Solving the equations, we have,  and

Part 3: Jacob is 4 years old and his mother is 40 years old.

Explanation:

Part 1: Let j represent Jacob's age, and let m represent his mother's age.

It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,

It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,

Simplifying this, we get,

Thus, the linear equation is

The linear equations are   and

Part 2: Solving the linear equation, we get,

Substituting  in

Simplifying, we get,

Hence,

Substituting  in

Solving the equations, we have,  and

Part 3: Since, j represents jacob and m represents the jacob's mother

Thus, Jacob is 4 years old and his mother is 40 years old.

Answer: She is 60 years old

Step-by-step explanation:

The solutions to the equation [tex]6x^{2} -0.5x=0[/tex] are [tex]x=0[/tex] and [tex]x=\frac{1}{12}[/tex].

To solve the equation [tex]6x^{2} -0.5x=0[/tex] by factoring, we first need to factor out the common factor of x from the expression:

[tex]x(6x-0.5)=0[/tex]

Next, we can simplify the expression inside the parentheses by factoring out a common factor of 0.5:

[tex]x(12x-1)=0[/tex]

Now, we have two factors being multiplied together that give a product of zero. According to the zero product property, this means that either [tex]x=0[/tex] or [tex]12x-1=0[/tex]. Solving for x in the second equation, we get:

[tex]12x-1=0[/tex]

[tex]12x=1[/tex]

[tex]x=\frac{1}{12}[/tex]

Therefore, the solutions to the equation [tex]6x^{2} -0.5x=0[/tex] are [tex]x=0[/tex] and [tex]x=\frac{1}{12}[/tex].

Answer:

If you were going the speed limit, after 3 hrs, you would go 165 miles.

If you were going 5 miles above the speed limit you would go 180 miles.

Step-by-step explanation:

55 x 3 = 165

55 + 5 = 60

60 x 3 = 180

Answer:

165miles

180miles

Step-by-step explanation:

If going 55mph for 3 hours,

55miles/hour * 3hour = 165miles

If going 60mph (5 over the limit) for 3 hours:

60miles/hour * 3hour = 180miles

Answer:

c = 4n

Step-by-step explanation:

The total cost (c) is going to be of the 4 notebooks together

We don't know how many notebooks Greg got, so it's represented by n.

It doesn't matter how many notebooks Greg purchased, because each of them were $4.

So to represent the total cost of the notebooks, you would write c = 4n

The Answer is 0.03

Step-by-step explanation:

Andrea = 3.12/8 flower per cupcake

   3.12/ 8 = .39

Corey = 2.25/ 7 flower per cupcake

   2.25/ 7 = .36

So Corey's recipe needs

( 0.39 - 0.36) = 0.03  flower per cupcake

x=width of pool

2x=length of pool

the dimensions of the rectangle forming the walkway and the pool are x+4 and 2x+4

the area of this rectangle minus the area of the pool is 196 square feet

(2x+4)(x+4)-(x)(2x)=196

2x^2+4x+8x+16-2x^2=196

combine similar terms

12x+16=196

12x=196-16

12x=180

x=180/12

x=15 feet is the width of the pool

check: 34*19-30*15=196

646-450=196

196=196

[tex]{ \tt{gradient = \frac{ - 3 - 1}{0 - ( - 1)} }} \\ = \frac{ - 4}{1} \\ = - 4[/tex]

Answer:

The gradient (slope) is -4.

Step-by-step explanation:

Note that two points on the graph through which the blue line passes exactly are (-2, 5) and (0, -3).  As we move from the first point to the second, x increases by 2 (the 'run') and y (the 'rise') decreases by 8.  Thus, the gradient, or slope, of this line is m = rise/run = -8/2, or m = -4.

Answer: 5/2

Yes it has to be 5/2

Answer:

5/2

Step-by-step explanation:

The sales tax rate = 5.29%

"Tax rate = (Tax amount / Price before tax) × 100% "

"Tax amount = Final price - Price before tax"

For given question,

Olivia pays $189 for a painting, including tax.

⇒ Final price = $189

The actual price of the painting is $179.50

⇒ Price before tax = $179.50

Using the formula of tax amount,

⇒ Tax amount = Final price - Price before tax

⇒ Tax amount = 189 - 179.50

⇒ Tax amount = 9.5

Now we find the sales tax rate.

Using the formula of tax rate,

⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%

⇒ Tax rate = [tex]\frac{9.5}{179.50} \times 100~\%[/tex]

⇒ Tax rate = 5.29%

Therefore, the sales tax rate = 5.29%

hope that helped <3

Answer:2 and 3

Step-by-step explanation:

First we have to take any point, I'll take (5,3).

X-axis represents number of pounds and y-axis represents total cost (in $).

So, 5 pounds = $3

=> 1 pound = $3/5

=> 1 pound = $0.6

=> 1 pound = 60 cents

Answer:

60c per pound.

Step-by-step explanation:

If 5lbs cost 3 dollars, 1lb = 3/5

3/5 = 0.6$

60c

Answer:

Rate of Change: $60 Per year

Step-by-step explanation:

We can find how many years are from 2000 to 2010 not overcouting. That is 10. Now, we do 1350 minus 750 because that's the change of the fee. That will give you 600. Now, 600 divided by 10, giving you how much change each year. That's 60.

So,

2000:750

2001:810

2002:870

2003:930

2004:990

2005:1050

2006:1110

2007:1170

2008:1230

2009:1290

2010: 1350

You can graph it out with that, now.
