Step-by-step explanation:

-(x + 3) = 8x - 4 - 2x

-x - 3 = 8x - 4 - 2x

combine like terms

-x - 3 = 6x - 4

add

-x = 6x -1

subtract

-7x = -1

divide

x = 1/7

Answer:

x = 1/7

Step-by-step explanation:

-(x + 3) = 8x - 4 - 2x

-x - 3 = 8x - 4 - 2x

-x - 3 = 6x - 4

-x = 6x -1

-7x = -1

Under his cell phone plan, Bentley pays a flat cost of $64.50 per month and $4 per gigabyte. He wants to keep his bill at $78.90 per month. How many gigabytes of data can he use while staying within his budget?

Answers

Answer:

3.6 gB

Step-by-step explanation:

You can think of this question in terms of the y = mx+b equation.

$78.90 is y because it is the total amount per month, $4 is m because it is the cost per gB, and $64.50 is b because it is the flat rate.

78.9 = 4x + 64.5

4x = 14.4

x = 3.6 gB of data (or 3 if it wants a whole number)

Rectangle ABCD has m∠BAC=4x+5and m∠ACD=5x−4. Find m∠CAD m∠CAD =

Answers

Answer:

m∠CAD = 49degrees

Step-by-step explanation:

For a rectangle ABCD if m∠BAC=4x+5and m∠ACD=5x−4, then;

m∠BAC = m∠ACD (alternate angles)

4x+5 = 5x - 4

4x-5x  = -4-5

-x = -9

x = 9

Also

m∠BAC+m∠CAD = 90

4x+5+m∠CAD = 90

4(9)+5+m∠CAD = 90

36+5+m∠CAD = 90

41+m∠CAD = 90

m∠CAD = 90-41

m∠CAD = 49degrees

Answer:

y° = 163°

Step-by-step explanation:

In this question we have to find the value of y.

We can solve this using the property of vertically opposite angles, I.e, vertically opposite angles are equal to each other. In this case the vertically opp. angle of y is 163°. So that makes y° = 163°

Find the least common denominator of the rational expressions below:
15/2x + 10 and -13/7x + 35

Answers

9514 1404 393

Answer:

  14(x +5)

Step-by-step explanation:

The denominator of the first expression is ...

  2x+10 = 2(x +5)

The denominator of the second expression is ...

  7x +35 = 7(x +5)

The least common denominator (LCD) is the product of the unique factors in these denominators:

  2×7×(x +5)

  = 14(x +5) . . . . least common denominator

  = 14x +70

5. A store sells milk in three different sizes. The 128 fl oz size costs $4.59. The 64 fl. oz container
costs $329. And, the 32 oz container cost $1.99. Which size has the lowest price per fluid
ounce?

Answers

Answer:

128 divided by $4.59 = 27.88671023965142
64 divided by $329 = 0.19452887537994
32 divided by $1.99 = 16.08040201005025

Therefore, the size which has lowest price per fluid ounce is 32 fl. oz container .

You're just suppose to divide the fluid oz and the cost for all the sizes,which ever has the lowest price is the answer.

Answer:

  r ≈ 19.0

  s ≈ 17.7

Step-by-step explanation:

The relevant trig relations are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

So, you have ...

  cos(43°) = r/26

  r = 26·cos(43°) ≈ 19.0

__

  sin(43°) = s/26

  s = 26·sin(43°) ≈ 17.7

Find the length of the intercepted arc and sector in a circle with a radius of 6 cm and a central angle of
132 degrees.

Answers

Answer:

Arc length = 13.818

Step-by-step explanation:

First, you will need to convert the 132 degrees to radians.

To convert, you'll have to multiply by π/180. So 132 x π/180 = 2.303.

Now with that value, you'll have to multiply by the radius to obtain the arc length.

2.303 x 6 = 13.818

Central angle = 132

Radius = 6

Diameter = 6 x 2 = 12

Arc length = 13.818

Answers

Answer:

14.4 ft

Step-by-step explanation:

The triangles formed by both ladders are similar to each other. Therefore, each corresponding sides will be proportional.

Thus, x + 8 would represent how far up the 10-foot ladder reaches the wall.

Therefore:

18/10 = (x + 8)/8

9/5 = (x + 8)/8

Cross multiply

9*8 = 5(x + 8)

72 = 5x + 40

72 - 40 = 5x

32 = 5x

Divide both sides by 5

32/5 = x

x = 6.4

The 10-foot ladder would be, 6.4 + 8 = 14.4 ft far up the wall.

The area of the triangle given in the figure is 6 square units.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find the area of triangle.

Area of triangle is 1/2 × Base × Height

The length of base is 6 units.

The length of height is 2 units.

Now let us plug in the value of base and height into the given formula of triangle.

Area of triangle =1/2×2×6

=6 square units

Hence, the area of the triangle given in the figure is 6 square units.

A department store buys 300 shirts at a cost of $3,600 and sells them at a selling price of $20 each. Find the percent markup. The percent markup is 1%. (Round to the nearest whole number as needed)​

Answers

Answer:

40%

Step-by-step explanation:

A department store buys 300 shirts at a cost of $3,600 and sells them at a selling price of $20 each. Find the percent markup.

The formula for Percent Markup is given as:

Selling price - Cost price/Cost price × 100

Cost price = $3,600

Selling price = $20 × 300 shirts

= $6000

Percent Markup = $6000 - $3600/6000 × 100

= 2400/6000 × 100

= 40%

The percent Markup is 40%
