someone pleeease help me asap !! thank you so much

Answer:

$99

Step-by-step explanation:

MP3 Player: $100

10% Mark up: $100/10= 10

Therefore, Mark-Up Price: $100+$10= $110

This was then Marked down by 10%.

Therefore,

10% Marked down: $110/10= $11

(We then take this away from the marked up price)

Hence, Final Price : $110-$11= $99

Answer:

b  ≥ 4

Step-by-step explanation:

12b + 12 ≥ 60

Subtract 12 from each side

12b + 12-12 ≥ 60-12

12b  ≥ 48

Divide each side by 12

12b/ 12 ≥ 48/12

b  ≥ 4

Close circle at 4  line to the right

Answer:

Step-by-step explanation:

12b + 12 ≥ 60

1) add -12 at both members

12b + 12-12 ≥ 60 -12

12b ≥ 48

2) divide both members by 12

12/12 b ≥ 48/12

b ≥ 4

for graph the solutions we have to draw two lines

the first one is an horizontal line that has as equation the right part of the inequality

y = 60

the second one is a line the that passes from the origin and interecpts the first line in (4;60). 4 is the the first number that can be a possible value of the inequality

Equation a line that passes for two points  A (0,0) , B (4,60)

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y - 60)/ (0 -60) = (x - 4) / (0-4)

(-y+60)/60 (-x+4)/4

-y + 60 = -15x + 60

y = 15x

the solutions of the inequality are all the points between the two lines with x≥4 and y≥60

Answer:

70

Step-by-step explanation:

2x and (4x-70) have the same measurements.

Set your formula up as

2x = 4x-70

2x-4x=-70

-2x=-70

x=35

Now substitute 35 in place of x

2x = 2*35 = 70

4x-70 = 4*35 - 70 = 70

Answer:

624 600

Step-by-step explanation:

624 612

you have to concentrate at the 1 because because it's at the tens place, if the 1 is not greater than 5 you don't have to do anything. you just have to remove the two numbers before the the number 6 and you so it automatically should be 624 600.

To round a number to the nearest hundredth , look at the next place value to the right (the tens this time). Same deal: If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right.

Answer:

0.05n + 0.25q = 1.60

q = 3n

0.05n + 0.25(3n) = 160

0.05n + 0.75n = 1.60...multiply by 100 to get rid of the decimals

5n + 75n = 160...answer D

Answer:

x = 7, -11

Step-by-step explanation:

(x + 2)^2 = 81

(7 + 2)^2 = 81      Take one value of x

9^2 = 81              Solve for the exponent

81 = 81                Final Answer

(x + 2)^2 = 81

(-11 + 2)^2 = 81   Take one value of x

9^2 = 81             Solve for the exponent

81 = 81

Understandings:

Understand how to solve for exponents

For example the ones that we used in this situation, in order to solve for an exponent, multiply the number by itself twice = 9 x 9 = 9^2 = 81

Answer:

x = 7 , x = - 11

Step-by-step explanation:

[tex](x+ 2)^2 = 81\\\\(x+2) = \sqrt{81}\\\\(x+2) = \pm 9\\\\x + 2 = 9 \ , \ x + 2 = - 9\\\\x = 9 - 2 \ , \ x = - 9 - 2\\\\x = 7 \ , \ x = -11[/tex]

Answer:

x = 9/10

Step-by-step explanation:

2(5x + 4) = 17

Distribute

10x+8 =17

Subtract 8 from each side

10x +8-8 = 17-8

10x = 9

Divide by 10

10x/10 = 9/10

Answer:

He traveled 520 miles

Step-by-step explanation:

8 x 65 = 520

Answer: 520 miles

Step-by-step explanation:

Data: Juan drove 8 hours

Drove at an average Speed of 65 mph

Miles driven=x

Only step: Multiply 65 by 8 which is 520

Explanation: Since Juan drove at an average speed of 65 miles per hour, that means he drove 65 mile for every hour he drove. So since he drove for 8 hours, you multiply 8 hours by 65 miles so that you get get the total amount of hours driven by him.

Don't forget to add "Miles" to the end of your answer because most math teachers tend to want that in an answer like this.

Answer:

382.50

Step-by-step explanation:

Area of the Shaded region = Area of the larger triangle - Area of the smaller triangle;

Let's find the area of the large triangle first;

A = 1/2(base) * (height)

A = 1/2(33) * (33)

A = 16.5 * 33

A = 544.5

Now let's find the area of the small triangle;

A = 1/2(base) * (height)

A = 1/2(18) * (18)

A = 9 * 18

A = 162

Area of the shaded region;

=> 544.5 - 162

=> 382.5 (if rounded to the nearest hundredths, 382.50)

Hope this helps!
