Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the sign, and flip the last fraction to solve

24/7 × 6/13 = 144/91

Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the '÷' sign to '× ' and reciprocal of the last fraction to solve.  

24/7 × 6/13 = 144/91

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

[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.

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].

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%

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

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

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

Answer:

65%×80=52

(80-52=28) no of classmates who liked sports

75%×64=48

(64-48=16) no of relatives who liked sports

no of classmates who liked sports - no of relatives who liked sports

= 28-16 = 12

Hence, 12 more of her classmates like sports as compared to her relatives

There are total 4 more of her classmates like sports as compared to her relatives.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the information given in the question,

Total number of students surveyed = 80

Percentage of students who like sports = 75%

So,

(80 × 65)/100

= 5200/100 = 52

Total number of Relatives = 64

Percentage of relatives who like sports = 75%

So,

(64 × 75)/100

= 4800/100 = 48

Then, the number more of her classmates like sports compared to relatives will be:

52 - 48

= 4

Answer:

x = -46.5

x + 1 = -45.5

Step-by-step explanation:

x + x + 1 = -92

2x + 1 = -92

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

   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
