WILL GIVE BRAINLIST Someone solve number 4 for me really quick must show work

Answer:

35x+72y

Step-by-step explanation:

well you are subtracting the terms 3x and -11y from the terms 38x and 61y. so to start you multiply 3x and -11 by negative one to get rid of the parentheses. you then you combine like terms.

Answer:

false

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

In order for two triangles to be congruent, they must have the exact same side lengths and angle measures. In this case, you know that the angles of the triangles are equal, but you are not given side lengths. In math, you can never assume that the lengths are equal just because they look like it. Therefore, the answer is B. False because you do not know a single side length. In the future, review the rules of congruent triangles: SAS, ASA, SSS, AAS, HL where S = side, A = angle, H = hypotenuse, L = leg.

Answer: X= days.        Equation: 16-2-3X=X

Step-by-step explanation:

there is none, it’s pretty straight forward.

But if you want to solve for how many days then it’s, 3 1/2 days

Answer:

F /r = k

Step-by-step explanation:

F=kr

Divide each side by r

F/r=kr/r

F /r = k

Answer:

d) x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Step-by-step explanation:

If x and y represent the number of tickets Paige purchased for the 2 types of seats.

Paige would like to attend at least 5 concerts.

This means, Paige would like to attend 5 or more concerts

Hence, the Inequality =

x ≥0

y ≥ 0

x + y ≥ 5

Also, we are told in the question that:

There are two types of seats at the concerts, which are priced at $29.50 and $43.00. Paige would like to spend no more than $200.

This means Paige was to spend less than or equal to $200

Therefore, the Inequality equation is:

29.5x + 43y ≤ 200

Therefore, the system of inequalities could Paige use to model this situation is option D

x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Answer:

d) x ≥0

y ≥ 0

x + y ≥ 5

29.5x + 43y ≤ 200

Answer:

The answer is the last one - t-40

Answer:

36

Step-by-step explanation:

Plug in -7 as m and 2 as n into the expression:

4 | m - n |

4 | -7 -2 |

Solve:

4 | -9 |

4(9)

= 36

Answer:

On the number line integers from 16 to 24 is the answer.

[tex]Answer:\boxed{y<-3}[/tex]

[tex]Explanation:[/tex]

[tex]9-y>12[/tex] Inequality

Let's start by simplifying both sides of the inequality.

[tex]-y+9>12[/tex]

Now subtract 9 from both sides.

[tex]-y+9-9>12-9\\-y>3[/tex]

Now divide both sides by -1.

[tex]\frac{-y}{-1}>\frac{3}{-1}[/tex]

[tex]y<-3[/tex]

Hope this helps!

Apparently i cant see the photo im am so sorry but do need pints.

Step-by-step explanation:

Answer:

option b & option c & option d

Step-by-step explanation:

option a: The left side   − 0.475  is not less than the right side  − 0.5 , which means that the given statement is false.

option b: The left side  − 0.3  is less than the right side  0.1 , which means that the given statement is always true.

option c: The left side  9.05  is greater than the right side  − 9.72 , which means that the given statement is always true.

option d: The left side  1.5  is equal to the right side  1.5 , which means that the given statement is always true.

Answer:

i think thats 12

Step-by-step explanation:

Answer:

r = 8

Step-by-step explanation:

Solve for r:

r + 4 = 12

Subtract 4 from both sides:

r + (4 - 4) = 12 - 4

4 - 4 = 0:

r = 12 - 4

12 - 4 = 8:

Answer: r = 8

Answer:

Answer:

Third quadrant

Step-by-step explanation:

Answer:

Quadrant III

Step-by-step explanation:

(-13, -12) is located in quadrant III because both the x values and y values are negative in the ordered pair, therefore they will be graphed on the part of the coordinate plane where the x and y values are also both negative simultaneously.

Answer:

84

Step-by-step explanation:

The interior sum of a pentagon is 540 degrees. If you add up all the given angles together, then it will add up to be 456. subtract 456 from 540, and you'll get your answer, which is 84.

Answer:

18

Step-by-step explanation:

252 is a composite number. The exponents in the prime factorization are 2, 2, and 1. Adding one to each and multiplying we get (2 + 1)(2 + 1)(1 + 1) = 3 x 3 x 2 = 18. Therefore 252 has 18 factors.

Now the aim of the above discussion is to internalize the mathematical relationships for open-end air columns in order to perform calculations predicting the length of air column required to produce a given natural frequency. And conversely, calculations can be performed to predict the natural frequencies produced by a known length of air column. Each of these calculations requires knowledge of the speed of a wave in air (which is approximately 340 m/s at room temperatures). The graphic below depicts the relationships between the key variables in such calculations. These relationships will be used to assist in the solution to problems involving standing waves in musical instruments.
