Since you know:

c = 30           substitute/plug it into the equation

f=(\frac{9}{5} )c+32       Plug in 30 for "c" in the equation

f=(\frac{9}{5} )(30)+32

f=(\frac{270}{5} )+32

f = 54 + 32

f = 86          (86°F if you need to add units)

The length of the side of a square is equal to the perimeter of the square divided by four. Which shows the correct graph relati
serious [3.7K]

Answer:

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Step-by-step explanation:

Let

x ----> the perimeter of the square

y ---> the side length of the square

Remember that

The perimeter of the square is given by the expression

P=4b

where

b is the length side of the square

solve for b

b=\frac{1}{4}P

That means

A ordered  pair in the coordinate plane following the rule

(x,y) -----> (x,x/4)

The y-coordinate is equal to the x-coordinate divided by 4

y=x/4

therefore

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Because

For the point (4,1)

substitute in the linear equation the value of x

y=4/4=1 ----> is ok

For the point (8,2)

substitute in the linear equation the value of x

y=8/4=2 ----> is ok

Jason owns a small textile company that produces shirts. On a particular day, Jason has one worker come into the shop to make sh
Vesna [10]

Answer:

Variables:

x → The number of hours the worker worked

y → The number of shirts the worker made.

System fo equations:

\left \{ {{25x+1.75 y=270} \atop {y=5x}} \right.

Step-by-step explanation:

Let be x the number of hours the worker worked and y the number of shirts the worker made.

Since:

  • Jason must pay the worker $25 per hour (which can be represented with 25x).
  • He must pay $1.75 per shirt for material costs (which can be represented with 1.75y).
  • The total expenses were $270.

You can write the following equation:

25x+1.75 y=270

Knowing that the worker created an average of 5 shirts per hour, you can write the other equation:

y=5x

Therefore, with this equations you can set up the following system of equations, which could be used to determine the number of hours the worker worked and the number of shirts the worker made:

\left \{ {{25x+1.75 y=270} \atop {y=5x}} \right.

Anthony wants to buy the same number of hats for 3 of his friends. He has $57 dollars, and each hat cost $5. What is the largest
Leona [35]
3 hats each is the largest amount Anthony can buy.

to get this answer i multiplied 3 friends by $5 ( amount of each hat) and got $15.
i divided that into $57 and got 3.8. So he can only afford to get each friend 3 hats each. Anthony should have $12 left

To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled.You Spent exactly $20 on a taxi which includes the $1 t
Helen [10]
<h3>Answer:  8 miles</h3>

=======================================================

Work Shown:

x = number of miles

2x = cost of traveling x miles, at $2 per mile, without including the $3 fee

2x+3 = total cost now including the $3 entrance fee, without tip

2x+3+1 = total cost plus $1 tip

2x+4 = amount you spent

2x+4 = 20

2x = 20-4

2x = 16

x = 16/2

x = 8

You traveled 8 miles.
