Answer:

$30

Step-by-step explanation:

$38-$8=$30

Answer: 30

Since Eugene just got $8, and the question is asking how much he had before that, we have to subtract 8 from 38.

38 - 8 = 30

So, the answer is 30. Hope this helps!

Answer:

3 1/9

Step-by-step explanation:

28/9=

9*3=27 r1

3 1/9

Answer: 3 1/9  

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 28 by 9 and keep only what is to the left of the decimal point:  28 / 9 = 3.1111 = 3

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.  28 - (9 x 3) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer.

Answer:

REEEEE ( i had to answer bc every time i refresh it brings me to this -_- sorry :(

Step-by-step explanation:

Step-by-step explanation:

From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.

If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;

v = change in distance/change in time

v = ΔS/Δt

v = 700-600/0.5-1.5

v = 100/-1

v = -100mi/hr

Since Speed = Distance/Time

-100 = 480/Time

Time = 480/-100

Time = -4.8s

Hence it will take the car 4.8seconds to travel 480miles.

Answer:

1.62 pounds

Step-by-step explanation:

Let x be the pounds of Arabica

Take the number of pounds times the cost of each of the coffees individually

This must be equal to the number of pounds times the cost together

x * 28 + 8.75 *3 = ( x+3) 15.50

28x+26.25=(x+3)15.50

Distribute

28x+ 26.25 = 15.50x + 46.50

Subtract 15.50x from each side

28x-15.50x +26.25 = 15.50x +46.50-15.50x

12.50x + 26.25 = 46.50

Subtract 26.25 from each side

12.50x +26.25-26.25 = 46.50-26.25

12.50x = 20.25

Divide each side by 12.5

12.5x/12.5 = 20.25/12.5

x =1.62

Answer:

[tex]\boxed {\angle 1 = 45\textdegree}[/tex]

Step-by-step explanation:

First you need to write an expression by using the following equations from both [tex]\angle 1[/tex] and [tex]\angle 2[/tex] and solve for [tex]x[/tex]:

[tex]\angle 1 = 2x + 13[/tex]

[tex]\angle 2 = 8x - 83[/tex]

[tex]2x + 13 = 8x - 83[/tex]

-Solve:

[tex]2x + 13 = 8x - 83[/tex]

[tex]2x + 13 - 8x = 8x - 8x - 83[/tex]

[tex]-6x + 13 = -83[/tex]

[tex]-6x + 13 - 13 = -83 - 13[/tex]

[tex]-6x = -96[/tex]

[tex]\frac{-6x}{-6} = \frac{-96}{-6}[/tex]

[tex]x = 16[/tex]

After you have found the value of [tex]x[/tex], you need to apply the value of [tex]x[/tex] to the equation of [tex]\angle 1[/tex] and solve for the measurement of [tex]\angle 1[/tex]:

-The value of [tex]x[/tex]:

[tex]x = 16[/tex]

-Solve for the measurement of [tex]\angle 1[/tex]:

[tex]2x + 13[/tex]

[tex]2(16) + 13[/tex]

[tex]32 + 13[/tex]

[tex]45\textdegree[/tex]

-The measurement of [tex]\angle 1[/tex]:

[tex]\boxed {\angle 1 = 45\textdegree}[/tex]

Answer:

Price of Adult tickets =$ 13

Price of student tickets =$ 8

Step-by-step explanation:

Lets us represent the price of adult tickets = x

The price of student tickets = y

On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.

= 10 × x + 13 × y = $234

= 10x + 13 y = 234

The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.

5 × x + 4 × y = $97

= 5x + 4y = 97

Hence:

10x + 13y = 234......Equation 1

5x + 4y = 97......... Equation 2

We solve by elimination method

Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x

10x + 13y = 234......Equation 1 × 5

5x + 4y = 97......... Equation 2 × 10

50x + 65y = 1170......Equation 3

50x + 40y = 970..... Equation 4

Subtract Equation 4 from Equation 3

25y = 200

y = 200/25

y = 8

Therefore the price of student ticket = $8

Note that

5x + 4y = 97......... Equation 2

5x + 4 × 8 = 97

5x = 97 + 32

5x = 65

x = 65/5

x = 13

Therefore price of adult tickets = $13

Answer:

63

Step-by-step explanation:

Jason age will be 63 years.

What is an expression?

Expression in math is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

The condition is given as;

'' Jason says that 10 less than one third of his age is 11 years old. ''

Now,

Let age of Jason = x years

Then, By the given condition we formulate;

1/3 x - 10 = 11

Solve for x as;

1/3 x - 10 = 11

Add 10 both side;

1/3 x - 10 + 10 = 11 + 10

1/3 x = 21

Multiply by 3;

x = 63

Thus, Jason age will be 63 years.
