Solve 2(x + 1) = 2x + 5. (1 point)

Answers

1) Expand.

2x+2=2x+5

2) Cancel 2x on both sides.

2=52=5

3) Since 2=52=5 is false, there is no solution.

No Solution

A circle has a diameter of 28 mm. What is its circumference?

Use 3.14 for 1, and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Answer: C=87.92 mm

Explanation: We can find the circumference using C=πd.

When using 3.14 for π, we will simply have C=3.14*28, which equals 87.92mm.

In order to get to work, Lindsay takes access roads that require a toll for drivers to use. She pays $4 each day to use the access roads. She also pays $5 each day to park her car at the company lot. Assuming the toll payments are used to plot the x-coordinate and the parking lot payments are used to plot the y-coordinate, which ordered pair represents how much money Lindsay spends during a 5-day work week?

The ordered pair that represents how much she spends on a 5-day week is (20,25)

The rates are given as:

[tex]Access\ Roads = \$4[/tex]

[tex]Parking\ Lot= \$5[/tex]

From the question, x represents the access to roads, and y represents the number of days she parked her car.

So, her daily expense is:

[tex]Daily = Access\ Roads \times x + Parking\ Lot \times y[/tex]

This gives

[tex]Daily = 4\times x + 5\times y[/tex]

[tex]Daily = 4x + 5y[/tex]

For a 5-day work week, her daily expense is:

[tex]Daily = 4 \times 5 + 5 \times 5[/tex]

[tex]Daily = 20 + 25[/tex]

Express as ordered pair

[tex]Daily = (20 , 25)[/tex]

Hence, the ordered pair that represents how much she spends is (20,25)

question 1 :- sum of all angles of a triangle is 180°

so, x + 39° + 25° + 15° = 180°

⇒x + 79° = 180°

⇒x = 101°

question 2 : draw the along with AD and make and triangle as shown in figure.

as ABCD is a parallelogram. so, angle FDE = 180° - x

and angle FED = 180° - x [ as FEA + FED = 180° ]

now from ∆DEF,

50° + 180° - x + 180° - x = 180°

⇒230° - 2x = 0

⇒x = 105°

also read : If (A + B) =(A-B) then the angle between the Ả and B.

Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

Last month Albert earned half of what Betty earned, while Betty earned $5000 more than what Calvin earned. If Donna earned twice what Calvin earned and Albert and Betty together earned $900 more than what Calvin and Donna earned together, how much did each person earn?

Answers

Answer:

Calving earning = 4400

Betty earning = 9400

Albert earning = 4700

Donna = 8800

Step-by-step explanation:

Given that :

Calving earning = c

Betty earning = c + 5000

Albert earning = (c + 5000) /2

Donna = 2c

c + 5000 + (c + 5000) /2 = 900 + c + 2c

c + 5000 + 0.5c + 2500 = 900 + 3c

1.5c + 7500 = 900 + 3c

7500 - 900 = 3c - 1.5c

6600 = 1.5c

c = 6600 / 1.5

c = 4400

Calving earning = c = 4400

Betty earning = 4400 + 5000 = 9400

Albert earning = (4400 + 5000) /2 = 4700

Donna = 2(4400) = 8800
