Please help- What is the value of X ?

sasho [114]

Answer:

$x=12\sqrt 2$

x = 100

Step-by-step explanation:

$\sin \: 45 \degree = \frac{12}{x} \\ \\ \frac{1}{ \sqrt{2} } = \frac{12}{x} \\ \\ \huge \red{ x = 12 \sqrt{2} } \\ \\ \\ \sin \: 45 \degree = \frac{x}{100 \sqrt{2} } \\ \\ \frac{1}{ \sqrt{2} } = \frac{x}{100 \sqrt{2} } \\ \\ x = \frac{100 \sqrt{2} }{ \sqrt{2} } \\ \\ \huge \purple{ x = 100 }$

Which of the following ordered pairs is a solution of the given system of

Artist 52 [7]

Answer:

x=-14 and y = 9

Step-by-step explanation:

hello

4x + 8y = 8 <=> divide by 4 both parts

(1) x + 2y = 4

(2) x + 3y = 13

(2) - (1) gives

x + 3y -x - 2y = 13 - 4 = 9

<=> y = 9

we replace in (1) x + 2*9 = 4

<=> x = 4 - 18 = -14

so x = -14

hope this helps

Can someone help me solve this :

Answer:

The total cost of 5 pillows and 7 sheets is $205.345

Step-by-step explanation:

Let x be the price of pillow case

We are given that the price of the pillows is 3 times as much as the price of a pillow case

Price of pillow = 3x

Price of 2 pillows = 2(3x)=6x

Price of 3 pillow case = 3x

At a store, 2 pillows and 3 pillow cases together cost $73.08.

So, 6x+3x=73.08

9x=73.08

$x=\frac{73.08}{9}$

x=8.12

So, Price of 1 pillow case = 8.12

Price of 1 pillow = 3x=3(8.12)=24.36

Price of 3 pillow =3(24.36)=73.08

Let y be the cost of 1 sheet

The total cost of 3 pillows and 4 sheets is $120.82

So, 73.08+4y=120.82

$y=\frac{120.82-73.08}{4}$

y=11.935

Price of 1 sheet = 11.935

Price of 7 sheets = 7(11.935)=83.545

Price of 5 pillows =5(24.36)=121.8

So,the total cost of 5 pillows and 7 sheets=83.545+121.8=205.345

Hence the total cost of 5 pillows and 7 sheets is $205.345
