Step-by-step explanation:

Because the answer is "1" it is positive. Negative and negative equals to positive. Positive and positive equals to positive.

Answer: 4 hours

Step-by-step explanation:

Assume x is the number of hours taken.

Garage A would therefore charge a total of:

= $9 + $1.50 * x

= 9 + 1.50x

Garage B would charge:

= $5 + $2.50 * x

= 5 + 2.50x

To find the number of hours it would take for them to be the same, equate both equations:

9 + 1.50x = 5 + 2.50x

9 - 5 = 2.50x - 1.50x

4 = 1x

x = 4 hours

That cost would be:

= 9 + 1.50 * 4

= 9 + 6

= $15

Answer:

x = -5 , y = 10

Step-by-step explanation:

As given ,

a = ( x₁ , y₁ ) = ( -6, 7)

b = ( x₂ , y₂ ) = (-1, -3)

For a -b = ( x₁ - x₂ , y₁ - y₂ )

            = ( -6 - (-1) , 7 - (-3) )

            = ( -6 + 1 , 7 + 3 )

            = ( -5 , 10 )

⇒ a - b = ( -5, 10 ) = ( x, y)

∴ we get

x = -5 , y = 10

Answer: $50,700 is the profit

If 150 televisions are sold, the profit is $50,700.

Profit is the total revenue less the total cost.

Profit = total revenue - total cost

Profit = (3x^2 + 180x) - (3x2 – 160x + 300)

Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)

27,000 + 24,000 - 300

Profit = $50,700

Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.

Step-by-step explanation:

I just did this question and got it right.

Answer:

The brother is 36 years old.

Step-by-step explanation:

b = brothers age

b - 18 = 18 | Given

b = 36 | Add 18 to both sides to cancel out -18 and get his age.

Answer:

36 years old or b-18 = 18

Step-by-step explanation:

Since there is an 18 year difference between the brother and the sister, all you have to do is subtract 18 from how hold the brother is. Since we know that the age of the sister is 18, the equation needs to be equal to 18. Using this, we know the equation is b - 18 = 18. When we add 18 to both sides we get that b=36.

Answer: 24

Step-by-step explanation:

The other information regarding the question is that the Medium pizza cost $9 while the Large pizza cost $15.

The number of medium sized pizza that Wright sold will be represented by x.

(5 × $15) + ($9 × x) = $291

$75 + 9x = $291

9x = $291 - $75

9x = $216

x = $216/9

x = 24

He sold 24 medium pizza

Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. With the help of decimals, we can write more precise values of measurable quantities like length, weight, distance, money, etc. The numbers to the left of the decimal point are the integers or whole numbers and the numbers to the right of the decimal point are decimal fractions. If we go right from ones place, the next place will be (1/10) times smaller, which will be (1/10)th or tenth place value.

Given:

8 4/9

Change the mixed fraction in normal fraction

=9*8+4/9

=72+4/9

=76/9

Step-by-step explanation:

since 3 x x is 3x and the sign in the bracket is addition you place it there then place 3 x 2.3

being 6.9.

1/3 x 9is 9/3 and 3 can multiply both sides to get 3/1 or 3 then bring the minus and 1/3 x 12 is 12/3 3 can multiply both sides to get 4/1 or 4

Answer:

$23780

Step-by-step explanation:

Given data

Let the original price be x

discount= 20%

price= $19,024

so that

20/100*x=x-19,024

0.2x= x-19,024

19,024=x-0.2x

19,024=0.8x

x= 19,024/0.8

x=23780

Hence the original price is $23780
