Answer:
There are 5 pages.
5
You read p pages.
5 - p,
or
(5 - p) ≤ 0
The answer to this expression will equal the amount you read.
The number of pages left to read will be = 5 - P.
We have a five page article.
We have to determine number of pages of this article left to read if you read P pages in the form of expression.
Express the amount of questions left to solve if you have a total of 'x' questions to solve and you have solved 'y' number of question (y < x) in the form of expression.Assume the number of questions left be n. Then -
n = x - y
According to the question, we have -
The number of pages in the article = 5
The number of pages completed = P
Hence, the number of pages left to read will be = 5 - P.

You drive 351.6 miles using 16.4 gallons of gasoline. At this rate, how many gallons of gasoline would you need to drive 1000 miles? Round your answer to the tenth place (one place after the decimal).
Answer:
46.6 gallons
Step-by-step explanation:
351.6 miles = 16.4 gallons
1000 miles = x gallons
simply cross multiply
351.6 × x = 1000× 16.4 gallons
351.6x = 16400 gallons
x = 16400÷ 351.6
x= 46.643913538
x = 46.6 gallons (rounded to the tenth place)

Evaluate k ^5 · m If k=2 and m=5
Answer:
160
Step-by-step explanation:
We are given the equation:
k^5 * m
and asked to evaluate for k=2 and m=5. Therefore, we must substitute 2 for k and 5 for m.
(2)^5 * 5
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Evaluate the exponent first.
—> (2)^5 = 2*2*2*2*2= 32
32 *5
Multiply 32 and 5.
160
The expression: k^5 * m when evaluate for k=2 and m=5 is equal to 160.

Given,
4 + y = 9.5
Equation : 4 + y = 9.5
Let's simplify this equation
To solve this equation, we must first subtract 4 from both sides of the equation.
Resultant equation :
4 - 4 + y = 9.5 - 4
0 +y = 5.5

What is the equation of the line passing through the points (4,8) and (-1,-12)
Answer:
y=4x-8 hope this helps:)
Step-by-step explanation:
Hey there!!
You can find the equation of a st.line passing through points using one point formula if only one point is given and slope is given , else find it by using two point formula (if 2 points are given).
Here, the points are, (4,8) and (-1,-12).
Using two point formula,
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Keep all values,
[tex](y - 8) = \frac{ - 12 - 8}{ - 1 - 4} (x - 4)[/tex]
Now, simplify them.
[tex](y - 8) = 5(x - 4)[/tex]
y - 8 = 5x -20
5x -y -20+8 = 0
Therefore, 5x - y -12 = 0 is the required equation.
Hope it helps...

The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of Arabica and Robusta beans is modeled by the equation below, where A = the pounds of Arabica and R = pounds of Robusta: (2 points) 700A + 1200R = 1,000,000 If a mixture contains 1000 pounds of Arabica beans, how many pounds of Robusta beans should be in the mixture?
Answer:
If a mixture contains 1000 pounds of Arabica beans, there should be 250 pounds of Robusta beans in the mixture.
Step-by-step explanation:
700A+1,200R=1,000,000
700(1000) +1,200R=1,000,000 - First, plug in the A value and simplify .
700000+1,200R=1,000,000 - Then, subtract 700,000 from both sides.
1,200R=300,000 - Finally, divide by 1,200 on both sides of the equation.
R=250 - This is your value for R, or the Robusta beans.
250 pounds of Robusta beans

When you switch your 8.5”x11” page from a portrait with 1” margins to landscape with 2” margins you lose how many square inches of writing space
Answer:
16.5 Squared Inches
Step-by-step explanation:
A 8.5''x11'' paper would be 7.5 in by 10 in with 1 inch margins. 7.5 x 10=75 in^2.
A landscape paper is 11''x8.5'' which would be 9 in by 6.5 in with 2 inch margins. 9 x 6.5=58.5 in^2.
75 inches squared-58.5 inches squared is 16.5 inches squared.
Therefore, you would lose 16.5 squared inches of writing space.

A temperature recorded in Antarctica was −123°F. The temperature recorded in the Sahara Desert was 135°F. How many degrees warmer is 135°F than −123°F
Answer:
The Sahara Desert is 258 °F warmer that Antarctica.
Step-by-step explanation:
Temperature at Antarctica = -123 °F
Temperature at the Sahara desert = 135 °F
The difference in temperature = 135 - (-123) = 135 + 123 = 258 °F
This means that the Sahara Desert is 258 °F warmer that Antarctica.

Jenna traveled to Mexico. Before returning home, she converted all her pesos back into dollars. How much did she receive if she exchanged 1047.5 pesos at a rate of 5 dollars = 115.21 pesos?
Answer:
Dollars= $45.46
Step-by-step explanation:
Giving the following information:
Pesos= 1,047.5
Exchange rate:
5 dollars= 115.21
First, we need to determine the exchange rate for 1 dollar:
1 dollar= 115.21/5
1 dollar= 23.042 pesos
Now, for 1,047.5 pesos:
Dollars= total pesos / exchange rate
Dollars= 1,047.5/23.042
Dollars= $45.46
Answer:
45.46 dollars
Step-by-step explanation:
what are the three integers all less than 25 whose range is 10 and mean is 13
Let x be the first integer , y be the second integer , and z be the third integer
x < y < z < 25
We know that
Median=13
Median=(x+y+z)/3
13=(x+y+z)/3
x+y+z=39------> equation 1
Range=10
The range is the difference between the largest number within the set and the smallest number in the set
So range=z-x
z-x=10------> z=x+10-----> equation 2
to find the solution we will assume different values of x (See the attached table)
terms
x < y < z < 25
z=x+10
y=39-z-x
The solution can be
7,15,17
8,13,18
9,11,19
