Answer:

B it seems like it's the most suitable answer

Step-by-step explanation:

p = 2(L+W)

98 < 2(x-2cm + 3x+5cm)

98 < 2x - 4 + 6x + 10

98 < 2x + 6x -4 +10

98 < 8x + 6........the inequality

98 - 6 < 8x

92 < 8x

11.5 < x.......the value of x

Answer:

a.N+3>4

Step-by-step explanation:

Let N be the number

According to question

Sum of N and 3 is given by

N+3

Atleast means greater than or equal to

At-least 4 means greater than or equal to 4

Therefore,

[tex]N+3\geq 4[/tex]

Hence, the inequality for the given sentence is given by

[tex]N+3\geq 4[/tex]

a.N+3>4

Answer:

2 wholes and 5/26

Step-by-step explanation:

convert the mixed number to improper fraction

= -19/6 / -13/9

since there is 2 negatives and (-)/ (-) means your answer is positve

to divide by a fraction multiply by the reciprocal of that fraction.

19/6 x 9/13

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

19/2 x 3/13

multiply 19/2 x 3/13

= 57/26

= 2 wholes and 5/26

= 2.1923076

Answer: 2/5

Step-by-step explanation:

perpendicular to y=2/5x-11 and has a y-intercept of 2. For a line to be perpendicular to another, their slopes must be "negative reciprocal". Therefore we KNOW that the slope is 2/5. also i dont know if you have already solved it but here you go

Answer:

  (d)  80y⁶ -10y³

Step-by-step explanation:

You only need to find the highest-degree term of the product to determine the correct answer choice.

That term is the product of the highest-degree terms of the factors:

  (-8y³)(-10y³) = 80y⁶

This matches choice D only.

Answer:

a. 10v/(v² - 16) b. 3 hours

Step-by-step explanation:

a. Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip.

Let v be the speed of the cyclist without the wind. The speed of the cyclist with the 4 mile per hour wind in the direction of the wind is v' = v + 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t' = 5/(v + 4)

Let v be the speed of the cyclist. The speed of the cyclist with the 4 mile per hour wind against the direction of the wind is v" = v - 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t" = 5/(v - 4).

So, the total travel time, T = t' + t"

= 5/(v + 4) + 5/(v - 4)

= [5(v - 4) + 5(v + 4)]/[(v + 4)(v - 4)]

= [5v - 20 + 5v + 20)]/(v² - 4²)

= 10v/(v² - 16)

b. What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?

If v = 6 miles per hour, then

T = 10v/(v² - 16)

= 10(6)/(6² - 16)

= 60/(36 - 16)

= 60/20

= 3 hours

Answer:

x=3.4

y=-6.75

Step-by-step explanation:

5x+4y=-10  (equation 1 )

-5x+3y=-17  (equation 2)

7y=-27

y=-6.75

substitution (equation 1 ) y=-6.75

5x-27=-10

5x=17

x=3.4

Answer:

C. 58.18 mph

Step-by-step explanation:

Answer:

C. 58.18

Step-by-step explanation:

The average speed means we will do miles per hour (mph). So if there are 640 miles for 11 hours the fraction would look like this:

640/11

We want to find the value for 1 hour so we need the bottom number(denominator) to be 1

Therefore we divide by 11 on the numerator and denominator by 11

58.181818(repeating)/1

This means we travel 58.181818... miles per hour.

If we round to the hundredths place we get 58.18 or option C.

Keep in mind that we can do this in ratio form and still get the same answer:

miles: hours

640:11

58.181818:1

Answer:

Step-by-step explanation:To find the better deal divide the price by the weight of each and compare:

1.49 / 120 = 0.012 per gram

0.89/ 100 = 0.0089 per gram

Buying loose is the better deal because the price per gram is smaller

Given:

The arithmetic sequence is −15, −33, −51, −69.

To find:

The nth term of the arithmetic sequence.

Solution:

We have,

−15, −33, −51, −69

Here,

First term: a = -15

Common difference is

[tex]d = -33-(-15)[/tex]

[tex]d = -33+15[/tex]

[tex]d = -18[/tex]

Now, nth term  of an arithmetic sequence is

[tex]a_n=a+(n-1)d[/tex]

Substitute a=-15 and d=-18.

[tex]a_n=-15+(n-1)(-18)[/tex]

[tex]a_n=-15-18n+18[/tex]

[tex]a_n=-18n+3[/tex]

Therefore, the nth term of the given arithmetic sequence is [tex]a_n=-18n+3[/tex].

Answer: 6 vans

Step-by-step explanation: one of the vans would only have 6 people

Answer:

6 vans! Hope it helps!

Step-by-step explanation:

Solution :

Given :

Perimeter, P = 16 m

The length is 4 times less then three times the width.

Let the length be l and width be w.

Therefore, according to the equation :

Length, l = 3w -  4  ................(i)

Perimeter, P  = 2(l+w)

                 16 = 2(l+w) ............(ii)

                 16 = 2l + 2w

                  8 = l + w ..............(iii)

Therefore solving equation (i) and (iii)

l = 3w - 4

8 = l + w

We get, w = 3  and l = 5

Answer:

16 divided by 3 = 5.3

Step-by-step explanation:

1/9÷2/5

=0.011111111111

=1⁄90

Let x = 0.555…

Then 10x = 5.555…

Subtract one from the other to get

10x - x = 5.555… - 0.555…

Notice how the fractional parts on the right cancel. This leaves you with

9x = 5

and so

x = 5/9

Answer:

59

Step-by-step explanation:

Since this fraction repeats the same number it must have a denominator of 9 and a numerator of the repeating digit the repeating digit is 5 so the fraction is 59

Answer:

$62.9 and $98.4

Step-by-step explanation:

Let the cost of tennis shoe be x

Since a jacket cost $35.50 more than a pair of tennis shoe,

Then cost of jacket would be

= $35.50 + x

Total cost of both items would be;

x + $35.50 + x = $161.30

2x = $161.30 - $35.50

2x = $125.8

x = $62.9

Therefore, cost of pair of tennis shoe is $62.9

Jacket cost would now be

= $35.5 + x

= $35.5 + $62.9

= $98.4

Answer:

5 x ^2  −  3 x  +  2  =  3 x  −  4 x  −  1  =  − x  −  1

Step-by-step explanation:

What is the question exactly?

Answer:

$82.5

Step-by-step explanation:

Step one:

Given that the percent of which is 10% amount to $8.25

We can estimate the of the Jeans as

Step two

Let the cost be x

10 percent of x= 8.25

10/100*x=8.25

0.1x=8.25

Divide both sides by 0.1 to get the value of x

x=8.25/0.1

x=$82.5

The cost of the jeans is

$82.5
