A store is going out of business. Everything is marked down 40%. How much do you pay now for an item that used to cost $150? Explain how you got your answer.

Answer:

12

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

52 = 8X + 8 + 2X + 4

Combining like terms:

52 = 10X + 12

Subtract 12 from both sides:

40 = 10X

Divide by 10:

X = 4

Now that we know X, we can figure out BC

BC = 2(4) + 4

BC = 8 + 4

BC = 12

Therefore BC is 12.

Hey there!

I don't know if it's too late, but oh well: The answer is 108°

Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:

180 - 72 =108°

Have a terrificly amazing day!

Answer:

∡APC = 108°

Step-by-step explanation:

∡ APB = 180°

∡ DPB + ∡ CPB + ∡APC = 180°

∡ BPD and ∡DPC have a sum of 72°

then:

72° + ∡APC = 180°

∡APC = 180° - 72°

∡APC = 108°

Step-by-step explanation:

Let x be the number of people in the queue, including yourself.

We have 2/3 x + 1 + 3/10 x = x.

=> 29/30 x + 1 = x

=> x/30 = 1

=> x = 30.

Hence there are 30 people in the queue.

Answer:

8

Step-by-step explanation:

7x - 4 = 5x + 12

7x - 5x - 4 = 5x - 5x + 12

2x - 4 = 12

2x - 4 + 4 = 12 + 4

2x = 16

2x/2 = 16/2

x = 8

Answer:

Consider all the info you are given:

The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.

You're given C(x) = 30x + 50, the monthly cost of the plan

'x' is the GB of data used OVER the allowance (2GB.)

They put over in italics to give you a hint to the solution.

(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26

The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)

(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)

So you the solve for x by setting C(x) = 50

30x + 5 = 50

30x = 50 - 5 = 45

x = 45/30

x = 1.5

Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.

Hope this helps...

side length1 = x

side length2 = y

2x + 2y = perimeter

2(4x) + 2(4)y = new perimeter

8x + 8y = new perimeter

new perimeter = 4 times the old perimeter

Answer:

x=−1/6 and y=0

Step-by-step explanation:

Answer:

There is one solution.

Step-by-step explanation:

x = - 1/6

y = 0

It can be solved simultaneously

6x - y = -1

6x + y = -1

Subtract equation two from equation one

-2y = 0

Divide both sides by-2

y = 0/-2

y = 0

Substitute 0 for y in either of the equations to get x

6x - 0 = -1

6x = -1

Divide both sides by 6

x = -1/6

Given:

Price of new AirPods = $199.99

Tax rate = 9%

To find:

How much will he spend?

Solution:

We have,

Price of new AirPods = $199.99

Tax rate = 9%

Tax value = 9% of $199.99

                = [tex]\dfrac{9}{100}\times 199.99[/tex]

                = [tex]17.9991[/tex]

Now,

Total money spend = Price of AirPods + Tax

                                = [tex]199.99+17.9991[/tex]

                                = [tex]217.9891[/tex]

                                [tex]\approx 217.99[/tex]

Therefore, the total money spend by James is $217.99.

Step-by-step explanation:

Answer:

X = 36/17

y = -8/17

Step-by-step explanation:

Since they both equal y, you could use them equal to each other.

(5/2)x-4=(-1/3)x+2

Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).

Step-by-step explanation:

The relative frequency for private vehicles is 97%, the relative frequency for public transport is 0 and the relative frequency for others is 2.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell by the total frequency.

We know the formula for the relative frequency:

[tex]\rm Rf = \frac{Frequency}{Total \ frequency}[/tex]

From the data given the Rf value for the private vehicle:

[tex]\rm Rf = \frac{1887}{1928} \times100[/tex]

Rf = 0.97×100 = 97%

For public transport:

= 0.005×100

= 0.5

= 0  (whole value)

For other:

= 0.022×100

= 2.2

=2 (whole value)

Thus, the relative frequency for private vehicles is 97%, the relative frequency for public transport is 0 and the relative frequency for others is 2.
