Answer:

-2.9375

Step-by-step explanation:

2x-14x+47=0

16x+47=0

16x=-47

x=-2.9375

Answer:

x=7+√ 2 or x=7-√ 2

Step-by-step explanation:

x^2-14x+47=0

Completing the square,

x^2-14x+49-2=0

x^2-14x+49=2

x^2-7x-7x+49=2

x(x-7)-7(x-7)=2

(x-7)^2=2

x-7=√ 2 or x-7=-√ 2

x=7+√ 2 or x=7-√ 2

Answer:

Richel could earn $ 85 if she works 10 hours

Step-by-step explanation:

As given

Richel earns in 4 hours = $34

Hence, Richel could earn $ 85

Answer:

x = -2

Step-by-step explanation:

Step 1: Write equation

2(x - 6) + 6 = 4x - 2

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

2(-2 - 6) + 6 = 4(-2) - 2

2(-8) + 6 = -8 - 2

-16 + 6 = -10

-10 = -10

Answer:

distribute the 2. add -12+6. add 2 to both sides. decide both sides by 2. x= -2

Answer:

4

Step-by-step explanation:

Answer:

The answer is

[tex] \huge y = \frac{5}{3} x - 4[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)\\[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (6,6) and slope 5/3

We have

[tex]y - 6 = \frac{5}{3} (x - 6) \\ y - 6 = \frac{5}{3} x - 10 \\ y = \frac{5}{3} x - 10 + 6 \\ [/tex]

We have the final answer as

[tex]y = \frac{5}{3} x - 4 \\ [/tex]

Answer: 594 and 30888

Step-by-step explanation:

5400 x 0.11 = 594

594 dollars in commission of one week

52 weeks in a year

52 x 594 = 30888 dollars made in 2011

594 dollars in commission of one week.

$30888 he make in commission in​ 2011.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Stocks sold= $5400

Commission each week = 11%

So, Commission on Stocks sold

= 5400 x 0.11

= 594

Thus, 594 dollars in commission of one week.

As, 1 Year = 52 weeks

So, He can make in 2011 = 52 x 594 = $30888

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every [tex]\dfrac12[/tex] cup of mustard.

That means , for [tex]\dfrac12[/tex] cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for  [tex]\dfrac12\times 2[/tex] cup of mustard. we need [tex]3\times 2[/tex] cups of ketchup.

⇒ for  [tex]1[/tex] cup of mustard. we need [tex]6[/tex] cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard

The  rate in cups of ketchup per cup of mustard is 6.

Given that,

Based on the above information, the calculation is as follows:

c = √58

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

Because we have a right triangle, we can use the Pythagorean Theorem to help us solve for missing side lengths:

7² + 3² = c²

49 + 9 = c²

58 = c²

c = √58

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

To solve, move all the x’s to one side and all the numbers. Remember when moving numbers to the other side of an equation, the sign changes from either a positive to a negative or vise versa.

9 + 3 = 4/3x + 2/3x

Next, add the like terms.

9+3=12

When adding fractions, add the numerator (top number), but first change denominator (bottom number) if not the same. Here, we don’t need to.

4/3x+2/3x=6/3x

So,

12 = 6/3x

Then, we have to divide each side by 6/3 to make the x alone.

12/6/3 = 6/3x/6/3

To divide with fractions, multiply the reciprocal (opposite number on number line):

12/1·3/6 = x

36/6 = x

6 = x
