Novosadov [1.4K]

Answer:

$\frac{4}{5}$ hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

We will equate both speeds as:

$\frac{1\frac{3}{10}}{x}=\frac{3\frac{1}{4}}{2}$

$\frac{\frac{13}{10}}{x}=\frac{\frac{13}{4}}{2}$

$\frac{13}{10\cdot x}=\frac{13}{4\cdot 2}$

Cross multiply:

$13\cdot 10\cdot x=13\cdot 4\cdot 2$

$10\cdot x=4\cdot 2$

$\frac{10\cdot x}{10}=\frac{4\cdot 2}{10}$

Therefore, it will take $\frac{4}{5}$ hour to complete $1\frac{3}{10}$ mile state fair race.

tickets were sold at four different gates. Gate D sold 24%. Gate A sold 36%. Gate C sold 14%. Gate B sold 26%. If 39 tickets wer

Drupady [299]

Answer:

150 tickets

Step-by-step explanation:

Given: Tickets sold at four different gates

Gate B sold 26 % tickets

Tickets sold at Gate B = 39

Let take x as total number of tickets sold at all four gates.

Now, using the value of gate B to find total number of tickets

∴ $26\% \times total\ ticket\ sold = 39$

⇒ $\frac{26}{100} \times x = 39$

Next, cross multiply both side

⇒ $x= \frac{39\times 100}{26} = 150\ tickets$

∴ Total tickets sold at all the four gates is 150

How do I get the answer

Ronch [10]

Answer:

Step-by-step explanation:

$- |3a + \sqrt{b} |$

By putting the values of a = -4 , b = 9,

$= - |3 \times ( -4) + \sqrt{9} |$

$= - | - 12 + 3|$

$= - | - 9|$

= -(9)

= -9 (Ans)

slavikrds [6]

Answer:

Step-by-step explanation:

2x - y = 8

x + y = - 2

3x = 6

3x /3 = 6/3 Dividing bot sides by 3 to find x.

x = 2

Plug in the value of x to find y.

2 ( 2) - y = 8

4 - y = 8

-y = 8 - 4

- y = 4

y = -4

The solution: ( 2, -4)
