Answer:

1) 4x-1/2 = x + 7

Answer : x=5/2

2) 3x + 2 = 2x+13/3

Answer: x=7/3

Step-by-step explanation:

1) 4x-1/2 = x + 7

Solution

Let's solve your equation step-by-step.

4x−1/2=x+7

Step 1: Simplify both sides of the equation.

4x+−1/2=x+7

Step 2: Subtract x from both sides.

4x+−1/2−x=x+7−x

3x+−1/2=7

Step 3: Add 1/2 to both sides.

3x+−1/2+1/2=7+1/2

3x=15/2

Step 4: Divide both sides by 3.

3x/3=15/2/3

x=5/2

2) 3x + 2 = 2x+13/3

Solution

Let's solve your equation step-by-step.

3x+2=2x+13/3

Step 1: Subtract 2x from both sides.

3x+2−2x=2x+13/3−2x

x+2=13/3

Step 2: Subtract 2 from both sides.

x+2−2=13/3−2

x=7/3

Answer:

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Monthly costs of a 2-adult and 3-children family in the Modesto metro area = US$ 7,846

Full-time worker = 4 weeks of 40-hour per month

Part-time worker = 2 weeks of 40-hour per month

2. Let's calculate the minimum monthly income and hourly wage per worker

Full-time worker hourly wage = Monthly costs/160

Part-time worker hourly wage = Monthly costs/80

Full-time worker hourly wage = 7,846/160

Part-time worker hourly wage = 7,846/80

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Full-time worker minimum monthly income = Hourly wage * 160

Part-time worker minimum monthly income = Hourly wage * 80

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

Using the midpoint formula, the coordinates of point U are: (9, 2).

The midpoint formula is: M[(x2 + x1)/2, (y2 + y1)/2]

Given the following:

Midpoint of TU is at: M(5,5)

Point T is at (1, 8), therefore, let:

M(5,5) = (x, y)

T(1, 8) = (x1, y1)

U(?, ?) = (x2, y2)

Plug in the values

M(5, 5) = [(x2 + 1)/2, (y2 + 8)/2]

5 = (x2 + 1)/2

10 = x2 + 1

10 - 1 = x2

9 = x2

x2 = 9

5 = (y2 + 8)/2

10 = y2 + 8

10 - 8 = y2

2 = y2

y2 = 2

The coordinates of point U are: (9, 2).

Answer:

(Choice A) A Yes

Step-by-step explanation:

Rita, John, and Kareem sent  17, 7, and 68 messages, respectively.

Use algebraic expressions to solve this problem.

Let x, y, and z be the number of messages sent by Rita, John, and Kareem, respectively.

If Rita, John, and Kareem sent a total of 92 text messages during the weekend, then:

x + y + z = 92

If Kareem sent 4 times as many messages as Rita, then:

z = 4 * x

z = 4x

If John sent 10 fewer messages than Rita, then:

y = x - 10

Evaluating z = 4x and y = x - 10 to the first equation:

x + y + z = 92

x + (x - 10) + 4x = 92

x + x - 10 + 4x = 92

6x = 92 + 10

6x = 102

x = 17

Recall that y = x - 10:

y = 17 - 10

y = 7

And z = 4x:

z = 4(17)

z = 68

If x, y, and z are the number of messages sent by Rita, John, and Kareem, respectively, then Rita, John, and Kareem sent 17, 7, and 68 messages, respectively.

The orange will fall 64 feet in 8 seconds.

Distance:

Distance is defined as how much ground an object has covered despite its starting or ending point.

Given,

The distance a falling object travels towards the earth is directly proportional to the square of the time that it falls.

And an orange falls 16 feet in 4 seconds.

Here we need to find the how far it will fall in 8 seconds.

Based on the given details,

We know the that distance is,

D = kt²  

where

k is the constant of proportionality.  

To find the value of k we have to apply the given values on the equation.

=> 16 = k x (4)²

=> 16 = k x 16

=> k = 16/16

=> k = 1.

So, in 8 seconds it will fall at

=> D = 1 x (8)²

=> D = 1 x 64

=> D = 64 feet.

Therefore, the orange will fall at 64 feet in 8 seconds.

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

The formula for a square's area, A = s², is the side length raised to the power of two. The 256 in2 section of the larger image was made available to us. Additionally, it was mentioned that the length of the expanded image is equal to the original image's length plus ten inches.

We can therefore create an equation to solve for x, which stands for the length of the original snapshot, based on the aforementioned statements.

A = s²

where s = ( x + 10 )

A = ( x+10 )² = 256

Answer:

£275

Step-by-step explanation:

To find how much Ben's rent is per month, we first have to find how much Ben spends on rent annually (every year). We can do this by multiplying his annual salary by the percentage spent on rent.  

22000 · 0.15 = 3300

Now that we know Ben spends 3300 on rent a year, we can divide that amount by 12 (the number of months in a year) to find out how much his rent is per month.

3300 / 12 = 275

Option B) is correct that is shape 2 is congruent to shape 1 because shape 2 is reflection of shape 1.

We know that two figures or objects are congruent if they have the same shape and size or they are the mirror image of each other.

Translation : It simply means moving. Every point should be moved in same distance and in same direction

Rotation : It means turning around a center.

Reflection : In this, the image is of the same size as the pre-image.

So according to the given figure we can see that the shape is not translated or rotated from a center but is reflected as shape 1 is the image of shape 2.

Hence shape 2 is congruent to shape 1 because shape 2 is reflection of shape 1.

Making Vi the subject of formula gives the following expression: Vi = √(Vf² - 2aX).

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In this exercise, you're required to describe the steps that should be taken to rearrange and make Vi the subject of formula. Therefore, the appropriate and required steps are listed as follows:

Vf² = Vi² + 2aX

Subtracting 2aX from both sides of the equation, we have:

Vf² - 2aX = Vi² + 2aX - 2aX

Vi² = Vf² - 2aX

Taking the square root of both sides, we have:
