if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?

Answers

Answer:

$63

Step-by-step explanation:

I believe you meant Richard worked for 7 hours and made $9 per hour.

In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.

7 hours x 9 dollars/hour = $63

Therefore, Richard earned $63 for his 7-hour work.

Additional Information

Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.

10 hours x 9 dollars/hour = $90

after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3

Answers

Answer:

x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 5 x - 6 = 3

Hint: | Solve the quadratic equation by completing the square.

Add 6 to both sides:

x^2 - 5 x = 9

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 25/4 to both sides:

x^2 - 5 x + 25/4 = 61/4

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 5/2)^2 = 61/4

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2

Hint: | Look at the first equation: Solve for x.

Add 5/2 to both sides:

x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2

Hint: | Look at the second equation: Solve for x.

Add 5/2 to both sides:

Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Answer:

  19.25 miles

Step-by-step explanation:

Antoine's rate before lunch was ...

  (5.25 mi)/(3 h) = 1.75 mi/h

Then his rate after lunch was ...

  2×(1.75 mi/h) = 3.5 mi/h

The distance he hiked after lunch was ...

  distance = speed × time

  (4 h)×(3.5 mi/h) = 14 mi

The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:

  5.25 mi + 14 mi = 19.25 mi

What is the sales tax on a jacket priced at $675 if the sales tax rate is 6%? The sales tax is $​

Answers

Answer:

$ 37.50

Step-by-step explanation:

We can rewrite this problem as: What is 6% of $625?

"Percent" or "%" means "out of 100" or "per 100",

Therefore 6% can be written as 6/100.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the sales tax we are looking for "t".

Putting this altogether we can write this equation and solve for t while keeping the equation balanced:

t=6100×$625

t=$3750100

t=$37.50

Answer:

40.50

Step-by-step explanation:

Sales price x sales tax rate = sales tax

675 x .06 (6%) = 40.50

Substitution method

Answers

Answer:

x=4 and y=−2

Step-by-step explanation:

y=−3x+10;y=−2x+6

Step: Solve y=−3x+10for y:

Step: Substitute−3x+10foryiny=−2x+6:

y=−2x+6

−3x+10=−2x+6

−3x+10+2x=−2x+6+2x(Add 2x to both sides)

−x+10=6

−x+10+−10=6+−10(Add -10 to both sides)

−x=−4

-x/-1 = -4/-1 (Divide both sides by -1)

x=4

Step: Substitute4forxiny=−3x+10:

y=−3x+10

y=(−3)(4)+10

y=−2(Simplify both sides of the equation)

Answer:

Solution is the point (4, -2)

Step-by-step explanation:

use the expression for y from the first equation in the second equation:

then the equation y = - 2 x + 6 becomes:

- 3 x + 10 = - 2 x + 6

add 3 x to both sides

10 = 3 x - 2 x + 6

10 = x + 6

subtract 6 from both sides

x = 4

Now replace x with 4 in the first equation to find y:

y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2

Therefore this is the point solution to the system:

(4, -2)

ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution

Answers

Answer:

Substitution is when you isolate a variable-

3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).

4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).
