3(2x+3y)=3(16)

-2(3x+4y)=-2(22)

--------------------------

6x+9y=48

-6x-8y=-44

------------------

y=4

2x+3(4)=16

Write a function rule for the table.


A. p = 7.50h

B. p = h + 15

C. p = 15h

D. h = 7.50p

Answers

Answer:

p = 7.50h

I got this correct, the answer is A. p= 7.50h

Step-by-step explanation:

The answer would be d because every two hours someone works they get $15 and for the equation we must know how much they work for one hour so that it works with the equation (we'd have to simplify it down do how much paid up per hour). so half of 15 is 7.5 so the equation would be p=7.50h (standing for $7.50 per hour).

The correct answer is:  [D]:   " p = 7.50 h " .

________________________________________________

The pay, "p" , is a function of the hours worked.

When h = 2,  (h = number of hours);  

        the pay, "p" ,  is equal to " 7.50 * 2 "  = 15.00 dollars" ; as shown on table.

When h  = 4  ;  p = " 7.50 * 4 = 30.00 dollars" ; as shown on table .

When h = 6 ; p = " 7.50 * 6 = 45.00 dollars" ; as shown on table.

When h = 8 ; p = " 7.50 * 8 = 60.00 dollars" ; as shown on table.

Addition in math is a process of combining two or more numbers.

Given that, A class spent hour on art and 1 /3 hours on art and [tex]1\frac{1}{3}[/tex] hour  on mathematics.

To find the total time, will add both the time,

[tex]=\frac{1}{3} + 1\frac{1}{3}\\ = \frac{1}{3} + \frac{4}{3} \\= \frac{5}{3} \\= 1\frac{2}{3}[/tex]

Hence, the students in total spend [tex]1\frac{2}{3}[/tex] hours in both the classes.

A tabletop in the shape of a trapezoid has an area of 5029 square cenimeters. Its longer base measures 123 cenimeters, and the shorter base is 65 cenimeters. What is the height?​

Answers

Answer:

Length of height = 53.5 cm

Step-by-step explanation:

Given:

Area of trapezoid = 5,029 cm²

Length of longer base = 123 cm

Length of shorter base = 65 cm

Find:

Length of height

Computation:

Area of trapezoid = [(a+b)/2]h

5,029 = [(123 + 65)/2]h

5,029 = [(188)/2]h

5,029 = [94]h

Length of height = 53.5 cm

Você precisa colocar suas renas, Raposa, Trovão, Cometa e Relâmpago, em uma fila única para puxar o seu trenó. No entanto, Cometa e Raposa são melhores amigos e precisam ficar juntos. De quantas maneiras você pode organizar as renas?

Answers

Answer:

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.

Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.

Hope this helps.    :)

Step-by-step explanation:

Spanish:

Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.

De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.

Four friends are all working in summer jobs. Their names are LaTisha, Zack, Steve and Michelle. The jobs they have found this summer include food server, lifeguard, construction worker and clerk at a grocery store. Determine who is working which job by using the clues below. 1.The person doing the food-serving job really like his work. 2.Zack and the lifeguard have known each other for years. 3.Both Michelle and the lifeguard are outside most of the time, and the other two are inside most of the time. 4.LatTisha and the person working construction met on their job last summer. 5.Neither Zack nor the food server worked last summer.

Answers

Answer:

LatTisha works as a Lifeguard

Zack works as a clerk at a grocery store

Steve works as a food server

Mitchel is a construction worker

Step-by-step explanation:

The parameters of the question are;

The names of the four friends are; LaTisha, Zack, Steve, and Michelle

The jobs found are; Food server, Lifeguard, Construction worker, and Clerk at a grocery store

1. The food server person likes his work

2. Zack and the lifeguard have known each other for years

3. Mitchel and the lifeguard are outside most of the time

4. LaTisha and the person working construction met on their job last summer

5. Neither Zack nor the food server worker worked last summer

We have;

Using known names,

Famale names are; LaTisha and Michelle

Male names are; Steve and Zack

Therefore

The food server worker is a guy, not Zack but  likely Steve

Mitchel works outdoors, therefore, she works in the other outdoor employment which is construction

The remaining two occupations are;

Lifeguard and Clerk at a grocery store

Given that Zack is not the lifeguard, we have;

Zack is the clerk at a grocery store

LatTisha is the Lifeguard
