You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.
Let x = the number of miles traveled and y = the total cost for the trip.
Answer:
Uber: y = .25x + 3
Lyft: y = .75x

Shelter A has a capacity of 300 beds and is 60% occupied. Shelter B is 30% occupied. The ratio of the occupancy of Shelter A to Shelter B is 1 : 2. How many beds are in Shelter B?
Answer:
1200 beds
Step-by-step explanation:
Shelter A has a capacity of 300 beds and is 60% occupied.
The amount of beds occupied =
60% × 300 beds
= 60/100 × 300
= 180 beds
Shelter B is 30% occupied.
Let the number of beds in Shelter B = x
30% × x = 0.30x beds
Hence:
180 beds + 0.30x beds
The ratio of the occupancy of Shelter A to Shelter B is 1 : 2.
Let the sum of the proportion = 1 + 2 = 3
Hence:
Number of beds in Shelter B =
2/3(180 beds + 0.30x beds) = 0.3x
2/3(180 + 0.30x) = 0.3x
Cross Multiply
2(180 + 0.30x) = 0.3x × 3
360 + 0.6x = 0.9x
Collect like terms
360 = 0.9x - 0.6x
360 = 0.3x
x = 360/0.3
x = 1200 beds
Therefore, the number of beds that are in Shelter B is 1200 beds

Write an algebraic expression that models the given situation.
24 more than the product of 2 and a number.
Enter the correct answer in the box.
Answer:
2x + 24
Step-by-step explanation:
The product of 2 and a number is: 2x
because product means multiply. 2 and a number means 2 times an unspecified number represented as x. 24 more than that product just means to add 24 to the product of 2x.
Answer:2x + 24

Bridget is 5 years older than Angad. Paul is 4 years younger than Angad. If the total of their
ages is 49, how old is the eldest of them?
Answer: Bridge is 21 years old
Step-by-step explanation:
Ok so after reading the question I already know that B (Bridget), A (Angad) and P (Paul) is 49 in the sum of age. I also know that B=A+5 and P=A-4. After that I can assume B=P+5+4. So now after we gather everything, the age of all of them is the same if we delete 5, 4, 4 (From B=P+5+4 and P=A-4). 49-5-4-4=36. So now lets assume they are all 12 (36/3=12). B is 5 years older so lets add 5 to B. B=17, A=12 and P=8. 8+12+17= 37. We now know that but 37 is 12 under 49, so lets add the average 12/3=4 so we add 4 to all of them. B=21 A=16 P=12. 21+16+12=49. So Bridge is 21 years old, Angad is 16 years old and Paul is 12 years old
15 point question
The pressure P of a gas varies inversely as its
volume V and directly as the temperature T. A
certain gas has a pressure of 2.7 atm, a
volume of 3.6 L, and a temperature of 324 K.
If the volume of the gas is kept constant and
the temperature is increased to 396 K, what
will the new pressure be?
Answer:
The new pressure P₂ is 3.3 atm
Step-by-step explanation:
Pressure of gas = 2.7 atm
Volume = 3.6 L
Temperature = 324 K
Now we are given that volume of the gas is kept constant.
Temperature is increased to 396 K
We need to find the pressure.
The formula used is: [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
We have P₁ = 2.7
T₁ = 324 K
T₂ = 396 K
P₂ = ?
Putting values in the formula and finding P₂
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}\\\frac{2.7}{324}=\frac{P_2}{396}\\P_2=\frac{2.7}{324}\times 396\\P_2=0.0083 \times 396\\P_2=3.3[/tex]
So, the new pressure P₂ is 3.3 atm

A city has a population of 330,000 people. Suppose that each year the population grows by 3.75%. What will the population be after 7 years?
Use the calculator provided and round your answer to the nearest whole number.
people
5
?
Answer:
429 058 people
Step-by-step explanation:
We will use the population growth formula.
Initial population * e ^ (rate * time)
With the information given, the equation will look like this:
[tex]330000 * e^(0.0375*7)[/tex]
(The numbers in the parantheses are exponents.)
Plug this into the calculator and you will get:
429 058 people.

Show that x=1 is not a solution to 4x+2 2 = 13.
Answer:
Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13
=> 5 +22 = 13 => 27 [tex]\neq[/tex] 13
So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

Company A rents a bounce house for $100 rental fee plus $20 per hour. Company B rents a bounce house for $40 per hour . Let h=the number of hours the bounce house is rented.Write an expression that shows the cost of renting a bounce house from each company
Answer:
A= 100+20h B=40h
Step-by-step explanation:
A=100+20h
B= 40h
Answer:
For company A:
100 + (20h)
OR
100 + (20 x h)
For company B:
40h
OR
40 x h
Step-by-step explanation:
For company A, you are multiplying 20 by h because you must pay $20 per hour. Then, you have to add 100 to that because there is a $100 dollar rental fee.
For company B, you are multiplying 40 by h because you must pay $40 per hour. There is no rental fee, so that means you don't have to add anything.

Choose the symbol that makes the following sentence true:
⅝ __ ⁷/12
<
=
>
5/8 is greater then 7/12.
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 12 is 24
For the 1st fraction, since 8 × 3 = 24,
5/8=5x3/8x3=15/24
Likewise, for the 2nd fraction, since 12 × 2 = 24,
7/12= 7x2/12x2=14/24
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
15/24>14/24 or 5/8>7/12

-3y+4x=13
-5y-6x=-67
Answer:
{x,y} = {67/16,-15/4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -8x + 26
[2] y = -4x + 13
// Plug this in for variable y in equation [1]
[1] 4x + 5•(-4x+13) = -2
[1] -16x = -67
// Solve equation [1] for the variable x
[1] 16x = 67
[1] x = 67/16
// By now we know this much :
x = 67/16
y = -4x+13
// Use the x value to solve for y
y = -4(67/16)+13 = -15/4
