Solve the equation: −3x − 3 +7x = 17 (SHOW UR WORK)

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Let absolute variation in the wait time at the bus stop = v

Variation = ±3 minutes

Average bus run through the city = 15 minutes

Hence, the minimum and maximum run values due to the variation can be modeled as:

|variation - average run| = ±3

|v - 15| = ±3

minimum : v = - 3 +. 15 = 12 minutes

Maximum : v = 3 + 15 = 18 minutes

Answer:

Step-by-step explanation:

│x - 3│= 15

This is the answer hope this help

Answer:

Yes, it should work.

Step-by-step explanation:

DC=AB  (because it is a rectangle and they are parallel)

DA=CB (because it is a rectangle and they are parallel)

DB=AC (given)

Those are all sides and gives enough information for us to know that it is congruent.

Answer: Add, subtract, multiply, divide

Step-by-step explanation:

Terms must be like terms in order to add or subtract. Terms do not have to be like if we are multiplying or dividing.

You cant add unlike terms when adding or subtracting, but you can use the exponent rules when multiply or dividing.

Answer:

[tex]-5<x<2[/tex]

Step-by-step explanation:

We have the inequality:

[tex]|2x+3|<7[/tex]

Use the definition of absolute value:

[tex](2x+3)<7\text{ or } -(2x+3)<7[/tex]

Let's evaluate each case individually.

Case 1)

We have:

[tex]2x+3<7[/tex]

Subtract 3 from both sides:

[tex]2x<4[/tex]

Divide both sides by 2:

[tex]x<2\\[/tex]

Case 2)

We have:

[tex]-(2x+3)<7[/tex]

Divide both sides by -1. Since we're dividing by a negative, flip our sign:

[tex]2x+3<-7[/tex]

Subtract 3 from both sides:

[tex]2x<-10[/tex]

Divide both sides by 2:

[tex]x<-5[/tex]

So, our solutions are, from least to greatest:

[tex]\{x|-5, 2\}[/tex]

We can see that our inequality is a greater than.

Remember, when dealing with absolute value:

When our sign is greater than (or equal to), our solution is an "or" inequality with our solutions being all values less than our lesser solution or all values greater than our greater solution.

When our sign is less than (or equal to), our solution is an "and" inequality with our solution being between our two solutions.

Since our inequality is a less than, our solution is all the values between our lesser solution and our greater solution.

Our lesser solution is -5. Our greater solution is 2.

So, the solution to the inequality is all values between -5 and 2. As a compound inequality, this is:

[tex]-5<x<2[/tex]

And we're done!

Answer:15

Step-by-step explanation: 1st multiple what’s in the parenthesis (3*3= 9 & 4*4= 16

Next write it out 22+(9-16)

Then you subtract 9 from 16 since it’s in parenthesis So it’s 22+(-7) and since you are adding a negative and a positive together you will have to subtract and keep the sign of the larger number so the answer is 15 since u needed to subtract but 22 is the larger number making it positive answer

Answer: no solutions

Step-by-step explanation:

The length of the diagonal of the room is approximately 21.2 feet when rounded to the nearest tenth.

Given information:

A square room in Denise's house measures 15 feet by 15 feet.

Since the room is square, the diagonal forms the hypotenuse of a right triangle whose legs are the sides of the square.

Each side of the square measures 15 feet, so we have:

d² = 15² + 15²

Simplifying:

d² = 2(15²)

d² = 2(225)

d² = 450

Taking the square root of both sides:

d ≈ 21.2

Answer:

The distance between the two points is [tex]\sqrt{85}[/tex] units

Step-by-step explanation:

Let us revise the rule of the distance between two point [tex](x_{1},y_{1})[/tex] and  [tex](x_{2},y_{2})[/tex]

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

∵ We need to find the distance between the two points (8, -7) and (1, -1)

→ Let [tex]x_{1}[/tex] = 8 and [tex]x_{2}[/tex] = 1

→ Let [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = -1

→ Substitute their values in the rule above

∴ [tex]d=\sqrt{(1-8)^{2}+(-1--7)^{2}}[/tex]

∴ [tex]d=\sqrt{(-7)^{2}+(-1+7)^{2}}[/tex]

∴ [tex]d=\sqrt{49+36}[/tex]

∴ [tex]d=\sqrt{85}[/tex]

→ Simplify the radical

∵ 85 = 5 × 17

→ Both of them are prime numbers

∴ The simplest form of [tex]\sqrt{85}[/tex] is [tex]\sqrt{85}[/tex]

∴ The distance between the two points is [tex]\sqrt{85}[/tex] units

To produce a finite straight line continuously in a straight line.

To describe a circle with any center and distance.

That all right angles are equal to one another.

That if a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the straight lines, if produced indefinitely, will meet on that side on which the angles are less that two right angles.*

Answer:

Total distance = 5.754 km

Step-by-step explanation:

Red lines of the right triangle show the layout of the race course.

Total length of the race course = Perimeter of the triangle

Perimeter of the triangle = Sum of the measures of all three sides

                                         = 1.83 + 1.524 + 2.4

                                         = 5.754 km

Therefore, total distance of the race course is 5.754 km.

Complete Question

You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/4 cup of walnuts for the oatmeal and 7/8 cup of walnuts for the salad. You have a 1/8 -cup scoop. Complete the descriptions of two different ways to find how many scoops of walnuts you will need. Enter all non-whole number answers as mixed numbers in simplest form.

Answer:

13 scoops

Step-by-step explanation:

Description 1

Step 1

3/4 cup of walnuts for the oatmeal

7/8 cup of walnuts for the salad

Total cups of walnuts needed for both salad and oatmeal =

3/4 cups + 7/8 cups

(3/4 + 7/8)

(6 + 7/8)

= 13/8 cups of walnuts

= 1 5/8 cups of walnuts

Step 2

You have a 1/8 -cup scoop

The number of cup scoops of walnuts need is calculated as

1 5/8 cups ÷ 1/8 cup scoop

= 13/8 ÷ 1/8

= 13/8 × 8/1

= 13 scoops

Therefore, 13 scoops of walnuts is needed.

Description 2

3/4 cup of walnuts for the oatmeal

7/8 cup of walnuts for the salad

1/8 cup scoop

Therefore,

(3/4 + 7/8) ÷ 1/8

=(13/8) ÷ 1/8

= 13 scoops of walnuts are needed

Answer:

a. –4(5x) = 12; OPEN

b. 4 x 6 = 24; TRUE

c. a + 4 = 6, when a = 2; TRUE

d. 4x = 19, when x equals 5; FALSE

Step-by-step explanation:

a. –4(5x) = 12 [-20x = 12 {Divide -20 from both sides} x = -0.6 So, if x is = -0.6, then it is true, so OPEN.

b. 4 x 6 = 24 [4 x 6 = 24 so TRUE]

c. a + 4 = 6, when a = 2. (Plug 2 in for a) 2 + 4 = 6; 6 = 6; TRUE

d. 4x = 19, when x equals 5. (Plug 5 in for x) 4(5) = 19; 20 is not = 19; FALSE
