Solve the equation: only write the number is the box
2( 5x+2)=54

Answers

Answer 1
Answer: x = 5

Explanation:

2(5x + 2) = 54
10x + 4 = 54
10x = 54 - 4
10x = 50
x = 50/10
x = 5

Therefore, x = 5

you and some friends have raised $250 to help make a video for a contest. You need $35 to buy video tapes. It costs $45 per day to rent the video camera for the first day and $30 for each additional day. Write an inequality to find the possible numbers of days you can rent the video camera.

Answers

Answer:

80 + 30 n ≥ 250

Number of days = 5

Step-by-step explanation:

Given:

Total money = $250

Video tape cost = $35

1st day for camera ranting = $45

Additional daily cost = $30

Find:

Inequality

Number of days

Computation:

Assume number of days = n

So,

35 + 45 + 30 n ≥ 250

80 + 30 n ≥ 250

30 n ≥ 170

n = 5 days

Number of days = 5

Desmond wants to sell his car that he paid $8,000 for 2 years ago. The car depreciated, or decreased in value, at a constant rate each month over a 2-year period. If x represents the monthly depreciation amount, which expression shows how much Desmond can sell his car for today?

Answers

Answer:
8,000 - 24x
Step-by-step explanation:
Let
y ----> depreciated value of the car
x---> rate of depreciation
t ----> the time in months
we know that
The linear equation that represent this situation is
y=8,000-xt
For
t=2 years=2*12=24 months
substitute
y=8,,000-x(24)
y=8,000-24x

105 centimeters to meters 105 centimeters= __m. _________

Answers

Answer:

1.05 meters

Step-by-step explanation:

To convert centimeters to meters, we need to divide the number by 100.

So 105/100= 1.05

Answer:

105 cm = 1.05 m

Step-by-step explanation:

For this problem, it is important to know metric conversions.  Metric conversions are based on powers of ten.  The prefix centi- means 100 (Like how a century is 100 years), and in the metric system is used to represent one-hundredths.

To convert 105 centimeters to meters, we need to divide by 10^2 or multiply by 10^-2 (both are the same).

So we can say the following:

105 cm * 10^-2  =  1.05 m

Hence, 105 centimeters is 1.05 meters.

The Earth is approximately a sphere of diameter 12742 km. The surface area of a sphere is given by the formula A = 4π r² Calculate the surface area of the Earth. Give your answer in metres squared and in standard form. (Take pi = 3.142) *

Answers

Answer:

5.101 x 10^14 m^2

Step-by-step explanation:

First you have to convert km to metres (the final answer must in metres).

So that would be 12742000m. Remember this is the diameter. The radius is half the diameter. So the radius would be 6371000m.

You then put it into the formula: 4 x π x 6371000².

And then you would get the answer: 5.101 x 10^14 m^2

Solve: 2x ≤ -2/3 (4x + 4)

Answers

answer: x ≤ 1

reason:

first, multiply 4x and 4 by -2/3, which leaves you with the equation 2x ≤ -8/3x + 8/3
then, you add 8/3x to both sides, making it 4 2/3x ≤ 8/3
divide both sides by 4 2/3 and you get x ≤ 1

Answer:

x ≤ 4/7

Step-by-step explanation:

Simplify the given 2x ≤ -2/3 (4x + 4) by multiplying both sides by (3/2):

(3/2)(2x) ≤ (3/2)(-2/3)(4x + 4)

We get 3x ≤ -4x - 4

Solve for x by combining like terms.  Add 4x to both sides, obtaining

7x ≤ 4

and so the solution is the set

x ≤ 4/7

un abuelo quiere repartir una cierta cantidad de manera proporcional entre sus tres nietos de 14, 10 y 6 años de edad ¿Aquien le corresponde mas?

Answers

Answer:

El niño con 14 años es el que tiene más derechos según su edad.

Step-by-step explanation:

Aquí, tenemos un abuelo que quiere compartir una cantidad de dinero entre sus nietos y queremos saber cuál de sus nietos tiene más derecho a este dinero proporcionalmente.

Creo que va a utilizar la edad de los niños como valor de proporcionalidad.

Así, compartiendo la cantidad entre sus hijos, tenemos; 14: 10: 6 que es 7: 5: 3

Entonces, lo que esto significa es que el niño con 14 años tomará 7 de los 15 lugares y es el que tomará la cantidad más alta.

Entonces, usando la edad como criterio, el niño con 14 años tiene más derecho a la cantidad a compartir.

How can parallel lines be used to compare figures E and F? Explain your reasoning.

Answers

Answer:

The similarities are

1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long

2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart  where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long

3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F

Figure F is essentially the translation of figure E three blocks to right and one block down

If the altitudes of two different triangles are in the ration of 2 is to 3 find the ratios of their areas and also the ratio of their corresponding medians

Answers

Answer:

The ratio of corresponding sides is 2:3

Step-by-step explanation:

Given, the corresponding medians of two similar triangles are in ratio of = 2:3

We know that,

The ratio of corresponding median = ratio of their corresponding altitude

So the ratio of the corresponding median is equal to the corresponding altitude is 2:3.

So, the ratio of their corresponding sides will also be 2:3.

And the ratio of the area of two triangle = square of the ratio of their corresponding sides.

solve the equation 1 = 6 (1 - p)

Answers

Answer:

p = 0.8333333333

Step-by-step explanation:

Simplifying

1 = 6(1 + -1p)

1 = (1 * 6 + -1p * 6)

1 = (6 + -6p)

Solving

1 = 6 + -6p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '6p' to each side of the equation.

1 + 6p = 6 + -6p + 6p

Combine like terms: -6p + 6p = 0

1 + 6p = 6 + 0

1 + 6p = 6

Add '-1' to each side of the equation.

1 + -1 + 6p = 6 + -1

Combine like terms: 1 + -1 = 0

0 + 6p = 6 + -1

6p = 6 + -1

Combine like terms: 6 + -1 = 5

6p = 5

Divide each side by '6'.

p = 0.8333333333

Answer:

0.833

Step-by-step explanation:

Simplifying

1 = 6(1 + -1p)

1 = (1 * 6 + -1p * 6)

1 = (6 + -6p)

Solving

1 = 6 + -6p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '6p' to each side of the equation.

1 + 6p = 6 + -6p + 6p

Combine like terms: -6p + 6p = 0

1 + 6p = 6 + 0

1 + 6p = 6

Add '-1' to each side of the equation.

1 + -1 + 6p = 6 + -1

Combine like terms: 1 + -1 = 0

0 + 6p = 6 + -1

6p = 6 + -1

Combine like terms: 6 + -1 = 5

6p = 5

Divide each side by '6'.

p = 0.8333333333

Simplifying

p = 0.8333333333
