A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first
ludmilkaskok [199]

Answer:

The hotel charge in city one before tax is $3750 and the hotel charge in city two before tax is $2250.

tep-by-step explanation:

Let a = the charge in 1st city before taxes

Let b= the charge in 2nd city before taxes

 

Based on the information given . We can have the following equation (1).

 

y = x - 1500  ......(1).

 

Interms of the information given , the following is formulated based on taxed paid .

 

0.065x + 0.06y = 378.75  .....(2).

Now we substitute equation (1) into (2).

 

0.065x + 0.06(x - 1500) = 378.75

0.065x + 0.06x - 90 = 378.75

0.125x - 90 = 378.75

0.125x = 468.75

        Therefor x=3750

Now x value into equation (1)

 

y = 3750 - 1500

y = 2250

 

 

The hotel charge in city one before tax is $3750 and the hotel charge in city two before tax is $2250.

You are baking a cake. The recipe asks for \frac{3}{5} 5 3 ​ cup of butter and you want to make \frac{1}{5} 5 1 ​ of the origina
MrRa [10]

Answer:

3/25 cup of butter

Step-by-step explanation:

You are baking a cake. The recipe asks for 3/5 cup of butter and you want to make 1/5 of the original recipe.

The calculation for the above question is given below:

1 recipe = 3/5 cup of butter

1/5 recipe = x

Cross Multiply

x × 1 recipe = 1/5 recipe × 3/5 cup of butter

x = 1/5 recipe × 3/5 cup of butter /1 recipe

x = 3/25 cup of butter

Therefore, you will need 3/25 cup of butter

Hey there (again)

x = 2y  \\ y = -2  \\ x = 2(-2) \\x= -4 \\ \\ \\ w + xy + 4x^2  = 2\\ w+-4(-2) + 3(-4)^2 = 2 \\ w + 8 + 3(16) = 2 \\ w + 8 + 48 = 2 \\ Subtract56: w + 56 =2 \\ 56 - 56 (Cancel) \\ 2 - 56 = -54 \\ w = -54

Answer: B  the simplification performed in step 2 is invalid or incorrect

Good luck on your assignment and enjoy your day

Misaka solved the radical equation x – 3 = square root of 4x-7 but did not check her solutions. (x – 3)2 = square root of 4x-7^2
Minchanka [31]

Answer:

x=8 is a true solution of the radical equation

Step-by-step explanation:

we have

x-3=\sqrt{4x-7}

Solve for x

squared both sides

(x-3)^{2}=4x-7\\\\x^{2}-6x+9=4x-7\\\\ x^{2}-10x+16=0

Convert to factored form

x^{2}-10x+16=(x-2)(x-8)

The solutions are x=2 and x=8

<u><em>Verify the solutions</em></u>

For x=2

Substitute in the original equation

2-3=\sqrt{4(2)-7}

-1=1 ----> is not true

therefore

x=2 is not a true solution of the radical equation

For x=8

Substitute in the original equation

8-3=\sqrt{4(8)-7}

5=5 ----> is true

therefore

x=8 is a true solution of the radical equation
