Step-by-step explanation:

2x+10=5x−2

Subtract 5x from both sides

2x+10−5x=−2

Combine 2x and −5x to get −3x.

−3x+10=−2

Subtract 10 from both sides.

−3x=−12

Divide both sides by −3.

Divide −12 by −3 to get 4.

Answer:

d = 15.8 m

Step-by-step explanation:

Apply the Pythagorean Theorem to find the length of the diagonal.  The correct equation for this particular rectangle is

d = √(9² + 13²) = √250 = √25·√10 = 5√10

To the nearest tenth, this comes to d = 15.8 m

Answer:

See photo.

Step-by-step explanation:

First, you need to find an already complete row, column, or diagonal and find its sum. This is the value that every other row, column, and diagonal needs to add up to. Next, find one that has two values filled in. Add these two numbers. Subtract them from the sum. The number you get is what needs to be in open box of that row/column/diagonal. Then you'll have another with two values, and you do the same thing for that one, and continue.

Example: 0+7+2= 9 so the sum for the left one is 9. you have a column with a 7 and a 3. 7+3= 10. 9-10= -1. then look at the diagonal. you have 2 and 3. 2+3=5, 9-5=4 so 4 is that one. and so on.

Answer:

$191.70

Step-by-step explanation:

total amount spent = cost of medicine + cost of tax + cost of shipping

cost of tax = 0.05 x $180 = $9

cost of shipping 0.015 x $180 = $2.70

total cost = $180 + $9 + 2.70 = $191.70

The answer is 2/7.

Step-by-step explanation:

If you flip a coin 7 times then 7 is the denominator, which stands for the total amount of times you flipped the coin. The numerator is 2, which is the amount of times you land on the same thing, in this case, landing on tails.

Answer:

0 units

Step-by-step explanation:

What's the length of one leg of a right triangle if the length of the hypotenuse is 25 units and the length of the other leg is 25 units?

The formula to solve for the sides of a right angled triangle

= Hypotenuse² = Opposite² + Adjacent ²

Hypotenuse = 25 units

One side = 25 units

To find the other side

√ 25² - 25²

= √625 - 625

= √0

= 0 units

The length of the other leg = 0 units

Complete question :

Lower-than-expected demand for LCD TVs has spurred manufacturers to cut prices in recent years. The average price P of a 32-in. LCD TV t years after 2005 can be approximated by P(t) 1052(0.793), where t0 corresponds to 2005 a) What was the average price of an LCD TV in 2005? in 2009? in 2011?

Answer:

1052 ; 416.01 ; 261.61

Step-by-step explanation:

Given the price function :

P(t) = t0(0.793)^t

P(t) = 1052(0.793)^t

Price in 2005 = 1052

The average price of LCD in 2005 is t0

t - t0 = 2005 - 2005 = 0

P(0) = 1052(0.793)^0 ;

P(0) = 1052 * 1 =

Price in 2005 = 1052

Price in 2009 :

t = 2009 - 2005 = 4

P(t) = t0(0.793)^t

P(4) = 1052(0.793)^4

P(4) = 1052 * 0.39534 = 416.0145

Price of LCD in 2009 = 416.01

Price in 2011

t = 2011 - 2005 = 6

P(t) = t0(0.793)^t

P(6) = 1052(0.793)^6

P(6) = 1052 * 0.248679 = 261.6103

Price of LCD in 2009 = 261.61

Answer:

9674.28 miles

Step-by-step explanation:

From the above question, we are given:

Central angle = 140°

Radius = 3960 miles

We are to solve for the distance = Arc length

The formula for Arc length when your central angle is in radians

r × θ

θ = 140°

Converting 140° to radians

140° × π/180 = 2.443rad

Hence,

3960 × 2.443 rad

= 9674.28 miles

The ship would travel 9674.28 miles.

Answer:

$405,44

Step-by-step explanation:

Equation: 499.99 - (499.99 x 15/100) - 1/10[499.99-(499.99 x 15/100)] + 6/100{1/10[499.99-(499.99 x 15/100) = x

Steps: x = (15 x 499.99)/100 = $74.9985

499.99 - 74.9985 = $424,9915

x = (424,9915 x 10)/100 = $42,49915

424,9915 - 42,49915 = $382,49235

x = $22,949541

382,49235 + 22,949541 = $405,441891

That can be rewritten as $405,44.

Answer:

x=3

x=−3

Step-by-step explanation:

2x^2 - 5 = 13

Subtract 13 from both sides.

2x^2 - 5 - 13 = 0

Subtract 13 from −5 to get −18.

2x^2 - 18 = 0

Divide both sides by 2.

x^2 - 9 = 0

Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).

(x−3)(x+3)=0

To find equation solutions, solve x−3=0 and x+3=0.

Answer:

72

Step-by-step explanation:

360/5 = 72

The angle of the rotation will be 72°. Then the correct option is B.

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Rotation does not change the size and shape of the geometry. But change the orientation of the image.

The pentagon is shown.

The angle of rotation of the pentagon such that the pentagon will remain in the same position.

Then the angle of the rotation is given as,

⇒ 360° / n

Where n be the number of the sides of the polygon.

In pentagon, the number of the sides will be 5.

Then the angle of the rotation will be

⇒ 360° / 5

⇒ 72°

Thus, the angle of the rotation will be 72°

Then the correct option is B.

Answer:

a + b = 780

Step-by-step explanation:

If we subtract the two equations we can ”eliminate“  a and b and find the value of z.

a-a = 0

b-b = 0

-10z = -700

z = 70

now we have to subistitute this value in the two equations

a + b -4(70) = 500

a + b + 6(70) = 1200

a+b - 280 = 500

a + b + 420 = 1200

If we simplify we have

a + b = 780

a + b =  780

Answer:

135

Step-by-step explanation:

Multiplying the quotient and divisor can give the divended.

So, -9 x -15 = 135

This is same for the other boxes at the top, try multiplying for the other boxes of their quotient and divisor together and you'll get the same number as the divended written on the other boxes.

Answer:

The initial value is;

y = 16

Step-by-step explanation:

Here, we want to get the initial value of y

Generally, for an exponential function,

we have the form as;

y = a•b^x

where the initial value is the value we have when x = 0

Looking at the given function, substituting x = 0

We have the function as;

y = 16(0.75)^0

y = 16 * 1

y = 16

So the initial value is 16

Step-by-step explanation:

Area of trapezoid = ½(a + b)h

where,

a = SK = 2 units

b = OC = 5 units

h = SO = 3 units

Plug in the values

Area = ½(2 + 5)*3

Area = ½(7)*3
