1/2 |2x-3|+5=13
Solve for x

Answers

Answer 1

Answer:

x=19/2

x=- 13/2

Step-by-step explanation:

multiply both sides by                                                         2 |2x -3|+10=26

move constant (10 to the right and change sign                |2x-3|=26-10

subtract the numbers                                                           |2x-3|=16

use absolute value (rewrite the absolute value                  2x-3=16

equation as two separate  equations one (+) and (-)           2x-3= -16

2x-3=16    move constant to the right

2x=16+3   add the numbers  

2x=19   divide both sides by 2

x=19/2

same steps with with second one

2x-2= -16

2x= -16 +3 move constant to the right change sign and add

2x= -13             divide both sides by two

x= -13/2

The  |   | are not (   ) .  They have different meaning , absolute value brackets. ok :)

Jake is making bracelets to give to his sisters. He uses 4 rainbow charms and 8 white star charms for his younger sister's bracelet. He makes his older sister's bracelet a little bigger, so he uses 5 rainbow charms and 10 white star charms. Does Jake use the same ratio of rainbow charms to white star charms in both bracelets?

Answers

Answer: Yes.

Step-by-step explanation: 4:8 simplifies to 1:2, since he used half as many rainbow charms as he did white stars. 5:10 also simplifies to 1:2. If they both have half as many rainbow charms as white, then both of his sister’s bracelets keep the same ratio.

Please, show your work !! I’ll give you brain if you do !!

Answers

Answer:

135.58 i'm pretty sure.

Step-by-step explanation:

First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that's the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So I first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, And got 48.8750. Lastly, I added. I added and got 135.575. So if you round it, it will be 135.58.

Consider the division expression 7 1/2 divided by 2. Select all multiplication equations that correspond to this division expression. 2 * ? = 7 1/2 7 1/2 * ? = 2 2 * 7 1/2 = ? ? * 7 1/2 = 2 ? * 2 = 7 1/2 I need help with this question!!! Which one is the answer!!!

Answers

Answer:

2 * ? = [tex]7\frac{1}{2}[/tex]

OR

? * 2 = [tex]7\frac{1}{2}[/tex]

Step-by-step explanation:

The given expression is:

[tex]7\frac{1}{2}[/tex] divided by 2.

The given expression a mixed fraction.

Let the result of the expression be equal to [tex]x[/tex].

Therefore, the expression can be written as:

[tex]7\frac{1}{2} \div 2 = x[/tex] ...... (1)

Multiplying equation (1) by 2:

[tex]7\frac{1}{2} = 2 \times x[/tex]

OR

[tex]7\frac{1}{2} = x \times 2[/tex]

Alternatively, this expression can be written as:

2 * ? = [tex]7\frac{1}{2}[/tex]

OR

? * 2 = [tex]7\frac{1}{2}[/tex]

Therefore, the following multiplication equations corresponding to equation (1) are:

2 * ? = [tex]7\frac{1}{2}[/tex]

OR

? * 2 = [tex]7\frac{1}{2}[/tex]

The cost, Y (in dollars) to provide for guests at a dinner party is proportional to the number x of guests attending the party. It costs 30 dollars to provide food for 4 guests.

Answers

Maybe you missed to add the complete question. After a little research I was able to find the complete question which is as follows:

''The cost y(in dollars) to provide food for guests at a dinner party is proportional to the number x of guests attending the party. It costs $30 to provide food for 4 guests. a. Write an equation that represents the situation. b. Interpret the slope. c. How much does it cost to provide food for 10 guests?''

So, I am solving based on this complete question.

Answer:

Please check the explanation.

Step-by-step explanation:

a. Write an equation that represents the situation.

As the cost and the number of guests are proportional.

So the equation of the form

[tex]y = mx[/tex]

Plug in the values y = 30 and x = 4 to find m

[tex]y = mx[/tex]

30 = m (4)

m = 30/4

    = 7.5

Now, substituting m = 7.5 in the equation y=mx

[tex]y = mx[/tex]

[tex]y = 7.5x[/tex]

b) Interpreting Slope

Given that the units for y are dollars, and the units for x are guests.

Thus, the slope 7.5 means it costs $7.5 per guest.

c) How much does it cost to provide food for 10 guests?''

We know the equation

[tex]y = 7.5x[/tex]

put x = 10

y = 7.5(10)

y = $75

Thus, it costs 75 dollars for 10 guests.

Step-by-step explanation:

a weight is attached to the end of a spring. its height after ttt seconds is given by the equation \qquad h(t)

Answers

The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

When is the maximum height?

This time is determined by the projectile's starting velocity as well as the angle of projection. When the projectile reaches a vertical velocity equal zero magnitudes, it has reached its maximum height. Furthermore, gravity would take over and accelerate the thing downward.

According to the given data:

Given that,

y = -2sin[tex](\frac{2\pi (t+1)}{7})[/tex] + 5

For maximum height,

sin(2π(t + 1))/7) = -1

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = 3π/2

t + 1 = 21/4

t = 4.25 seconds

Hence,

we can conclude that at t = 4.25 seconds,

The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

Find the final sale price after these two discounts: Original price $65.00. Take 20% off, and then take $5 off that amount.

Answers

Answer:

20% 0f $65.00 is $13

$13 - $5= $8

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 65.00.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$65.00=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$65.00=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{65.00}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{65.00}=\frac{20}{100}$

$\Rightarrow x=13$

Therefore, $20\%$ of $65.00$ is $13$

What is m ZABC?

mABC = 60°
mABC = 67 °
mABC = 120°
mABC = 127°​

Answers

Answer:

           m∠ABC = 127°

Step-by-step explanation:

From triangle BCD:

m∠BCD + m∠CDB + m∠DBC = 180°

67° + 60° + m∠DBC = 180°

m∠DBC = 180° - 127°

An angle ABD is straight angle, so:

m∠ABC + m∠DBC = 180°

m∠ABC +  180° - 127° = 180°

m∠ABC = 127°

Both the race cars will hit the ground at the same time.

 

The concept used here is free fall formula which can be defined as . Free fall means that an object is falling freely without a forces acting upon it except gravity, a described constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1\/2 gravity x the square of the time falling. Velocity is described as gravity x time.

Here the two cars are free falling in the vertical direction and the initial velocity in the vertical direction is zero. So the landing time of both the cars is only related to the height and the acceleration of gravity.

Hence, the cars are falling from the same height, h and g are the same so they take same time to touch the ground.
