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:

(1,-1)

Step-by-step explanation:

if its asking for a reflection on the x-axis, change the y's to the opposite of what it is.

Example, (5,6) change it to (5,-6)

its the same thing for the reflection on the y-axis

(7,-8) change it to (-7,-8)

Answer:

therefore z is 5

Step-by-step explanation:

2x+y- Z=17

2(10)+2-Z=17

20+2 -Z=17

22-Z =17

22-17=Z

5=Z

Z=5

Answer:

331.705 I believe

Step-by-step explanation:

You just move the decimal point as many times as it is moved in the first problem. So 1793 to 1.793 means you moved the decimal to the left 3 times.

Answer:

0.170940171

Step-by-step explanation:

The required divide of 7.2 divided by 42.12 is 0.170940171 which is none terminating recurring decimal.

Given that,
To evaluate the solution of the numeral 7.2 divided by 42.12.

A recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

Here,
According to the question,
7.2 / 42.12 = 0.170940171
Which is a recurring decimal.

Thus, the required divide of 7.2 divided by 42.12 is 0.170940171 which is none terminating recurring decimal.

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: 7

Step-by-step explanation:

(3(2)-4)+(-(2)+7)

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:

I think its 1.62 pounds

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!
