1 ≤ x + 7 < 7
explain how u got the answer plz

Answers

Answer 1

Answer:

-6 ≤ x < 0

Step-by-step explanation:

Subtract the 7 on both sides to get x isolated.

Answer 2

Answer:

-6 ≤ x < 0

Step-by-step explanation:

This is the answer because:

1) First, we have to isolate the x

2) In order to isolate the x, you have to subtract 7 from 1 and 7

1 - 7 = -6

7 - 7 = 0

Therefore, the inequality is -6 ≤ x < 0

Hope this helps! :D

What is the value of x?

Answers

Answer:

x= 20

Step-by-step explanation:

did it on edg2020 a while ago

The value of x using vertical angle is 20.

Thus, option (A) is correct.

Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. When two lines intersect at a point, they create four angles around that point. The two pairs of opposite angles are called vertical angles.

Each pair of vertical angles is congruent, meaning they have equal measures.

Given:

<TRS = x + 40

<VRW = 3x

From the figure, the angles <TRS and <VRW are vertical angles.

So, <TRS = <VRW

x+ 40 = 3x

To do this, subtract x from both sides of the equation:

x + 40 -x = 3x - x

40 = 2x

Dividing both sides of the equation by 2:

40 /2 = x

x= 20

So, the solution is x= 20.

Thus, option (A) is correct.

diego paid $27 to have 3 pizzas delivered and $35 to have 4 pizzas delivered.
What is the price of one pizza

Answers

Answer:

9 or 8.25

Step-by-step explanation:

27/3=9

35/4=8 3/4

To find the price of one pizza, we can set up a system of equations based on the given information. Let's assume that the price of one pizza is "x" dollars.

From the first scenario, we know that Diego paid $27 to have 3 pizzas delivered. Thus, we can write the equation:[tex]3x = 27[/tex] From the second scenario, we know that Diego paid $35 to have 4 pizzas delivered. Thus, the equation becomes: [tex]4x = 35[/tex] To solve this system of equations, we can use the substitution method .

From the first equation, rearranging it to solve for "x," we find: [tex]x = 27/3 x = 9[/tex]Substituting the value of "x" into the second equation, we find:[tex]4(9) = 35 36 = 35[/tex] This means there is no solution, indicating that there might be an error in the given information.

However, if we assume an average price for each pizza, we can calculate it. The average price per pizza can be found by dividing the total amount spent by the number of pizzas. Thus, for both scenarios combined, Diego spent $62 on 7 pizzas, leading to an average price of: [tex]62/7 ≈ $8.86[/tex]Therefore, the estimated price of one pizza is approximately $8.86.

work of the crew that did their landscaping. Each respondent rated the quality as high, medium, or low.
The data were compiled and reported in the table, which shows the relative frequency of each rating
by row. A total of 70 people responded about the quality of the work of Crew B. How many of these
people gave Crew B a rating of "high"?

Answers

Answer:

35

Step-by-step explanation:

14 of these people gave Crew B a rating of high.

What is the relative frequency?

A relative frequency reflects how frequently a certain type of occurrence occurs in relation to the overall number of observations. It is a frequency type that employs percentages, proportions, and fractions.

Given that, A total of 70 people responded about the quality of the work of Crew B. relative frequency of crew B getting high as the rating is 0.200.

Hence,

the number of people who gave B a rating of "high" = 0.200* 70 = 14

The required value of f(9) is -142.

What is a function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

Now the given function is,

f(x) = -x^2 - 9x + 20

Now for finding f(9), putting x = 9 in f(x) we get,

f(9) = -9^2 - 9*9 + 20

Solving we obtain,

f(9) = -81 - 81 + 20

Simplifying we get,

f(9) = -162 + 20

Thus,

f(9) = -142

this is the required solution for f(9).

Thus, the required value of f(9) is -142.

I think the correct answer would be C, it might be A but I’m pretty sure its C. If you google a graph and Mark all the coordinates you’re given and connect the dots you will be given a shape. A parallel a gram would be something like a square, rectangle, etc hence the word “PARALLEL” meaning the opposite angle is straight, the same length, and going in the same direction as the one opposite to it. The dots on the graph do not make a parallelogram this concluding the answer is “ no “ leaving it to be A or C and I believe it would be C because the lines opposite of it do not have the same length

Ivan rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 87 cents for each mile driven. Ivan had to pay $220.83 when he returned the truck. For how many miles did he drive truck?

Answers

Answer:

232

Step-by-step explanation:

First you do 220.83 - 18.99 which is 201.84 so you know the price he spent for the miles driven.

Then you divide that number by .87 which gives you 232 for the number of miles driven.

Answer:232

Step-by-step explanation:First of all 87 cents in a decimal it is .87 on to the summery of the question.220.83-18.99=101.84/.87=and the answer is 232.

18.99 needs to be subtracted from 220.83.It will equal 101.84.You will need to divide .87 in to 101.84 to get the answer 232

1) 39

2) 59

3) 53

4) 38

5) 9

6) 12

7) 15

8) 11

Step-by-step explanation:

if the angles together is a right angle than you just subtract the angle that is known from 90 and you get your other angle.

1) 90 - 51 = b = 39

2) 90 - 31 = b = 59

3) 90 - 37 = b = 53

4) 90 - 52 = b = 38

5) 90 - 56 = 34

34 = 3x + 7

3x + 7 - 7 = 3x

34 - 7 = 27

3x = 27

3x  / 3 = x

27 / 3 = 9

6) 90 - 48 = 42

42 = 3x + 6

3x + 6 - 6 = 3x

42 - 6 = 36

3x = 36

3x / 3 = x

36 / 3 = 12

7) 90 - 47 = 43

43 = 2x + 13

2x + 13 - 13 = 2x

43 - 13 = 30

2x = 30

2x / 2 = x

30 / 2 = 15

8) 3x +  5x + 2 = 90

8x + 2 = 90

8x + 2 - 2 = 8x

90 - 2 = 88

8x = 88

8x / 8 = x

88 / 8 = 11
