Answer: $40.95

2)156.25/50= 3.125
3.125x16=50
x=50

3) 210     42
    ------ = -----
       x       100

210x100= 21000
21000÷42=500

500 people were surveyed

Answer: 1) Final price of the jacket = $40.95

2)  x = 50

3)  Total number of people is 500

Step-by-step explanation:

since we have given that

1) Original price of jacket = $65.00

Discount rate on jacket = 40%

Discount is given by

\frac{40}{100}\times 56\\\\=0.4\times 65\\\\=\$26

So, the price becomes

\$65-\$26\\\\=\$39

Rate of sales tax = 5%

Amount of sales tax is given by

\frac{5}{100}\times 39\\\\=0.05\times 39\\\\=\$1.95

Final price of the jacket is given by

39+1.95\\\\=$40.95

2) \frac{16}{50}=\frac{x}{156.25}

We need to solve for 'x':

\frac{16}{50}=\frac{x}{156.25}\\\\16\times 156.25=50\times x\\\\2500=50x\\\\\frac{2500}{50}=x\\\\x=50

Hence, x = 50

3)Number of people who like football = 210

Percent of people who like football = 42%

Let the total number of people be x

According to question,

\frac{42}{100}\times x=210\\\\0.42x=210\\\\x=\frac{210}{0.42}\\\\x=500

Hence, total number of people is 500.

Answer:

k = 9/4

Step-by-step explanation:

To find k, use the equation

y = kx

Pick a point

72 = k *32

Divide each side by 32

72/32 = k

Solve the following System of Three Equations:<br> x−3y+z=−15<br> 2x+y−z=−2<br> x+y+2z=1
SashulF [63]

Answer:

x = -3 , y = 4 , z = 0

Step-by-step explanation:

Solve the following system:

{x - 3 y + z = -15

2 x + y - z = -2

x + y + 2 z = 1

Hint: | Choose an equation and a variable to solve for.

In the first equation, look to solve for z:

{x - 3 y + z = -15

2 x + y - z = -2

x + y + 2 z = 1

Hint: | Solve for z.

Subtract x - 3 y from both sides:

{z = 3 y + (-x - 15)

2 x + y - z = -2

x + y + 2 z = 1

Hint: | Perform a substitution.

Substitute z = -15 - x + 3 y into the second and third equations:

{z = -15 - x + 3 y

15 + 3 x - 2 y = -2

x + y + 2 (-15 - x + 3 y) = 1

Hint: | Expand the left hand side of the equation x + y + 2 (-15 - x + 3 y) = 1.

x + y + 2 (-15 - x + 3 y) = x + y + (-30 - 2 x + 6 y) = -30 - x + 7 y:

{z = -15 - x + 3 y

15 + 3 x - 2 y = -2

-30 - x + 7 y = 1

Hint: | Choose an equation and a variable to solve for.

In the second equation, look to solve for x:

{z = -15 - x + 3 y

15 + 3 x - 2 y = -2

-30 - x + 7 y = 1

Hint: | Isolate terms with x to the left hand side.

Subtract 15 - 2 y from both sides:

{z = -15 - x + 3 y

3 x = 2 y - 17

-30 - x + 7 y = 1

Hint: | Solve for x.

Divide both sides by 3:

{z = -15 - x + 3 y

x = (2 y)/3 - 17/3

-30 - x + 7 y = 1

Hint: | Perform a substitution.

Substitute x = (2 y)/3 - 17/3 into the third equation:

{z = -15 - x + 3 y

x = (2 y)/3 - 17/3

(19 y)/3 - 73/3 = 1

Hint: | Choose an equation and a variable to solve for.

In the third equation, look to solve for y:

{z = -15 - x + 3 y

x = (2 y)/3 - 17/3

(19 y)/3 - 73/3 = 1

Hint: | Isolate terms with y to the left hand side.

Add 73/3 to both sides:

{z = -15 - x + 3 y

x = (2 y)/3 - 17/3

(19 y)/3 = 76/3

Hint: | Solve for y.

Multiply both sides by 3/19:

{z = -15 - x + 3 y

x = (2 y)/3 - 17/3

y = 4

Hint: | Perform a back substitution.

Substitute y = 4 into the first and second equations:

{z = -x - 3

x = -3

y = 4

Hint: | Perform a back substitution.

Substitute x = -3 into the first equation:

{z = 0

x = -3

y = 4

Hint: | Sort results.

Collect results in alphabetical order:

Answer:  {x = -3 , y = 4 , z = 0
