If he used 3 gallons of gas. Then the amount of the gas in the tank after driving for 2 hours will be 9 gallons.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.
Then the amount of the gas in the tank after driving for 2 hours will be
The amount of gas used in 2 hours will be
Used gas = 2 x 1.5
Used gas = 3 gallons of gas
Then the remaining amount will be
Remaining amount of gas = 12 - 3
Remaining amount of gas = 9 gallons

8. Melody subscribes to a coffee service. For $10 a month, Melody is able to purchase a cup of coffee for the
discounted price of $2 for each cup. This situation can be modeled by the function f(x) = 2x+10, where x
represents the number of cups of coffee Melody can purchase. This membership caps the number of cups of
coffee that can be purchased each month at 6.

Answer:
Domain: 0 <= x <= 6
Range: 10 <= x <= 22
Step-by-step explanation:
There is no minimum to the number of cups she can purchase, thus x > 0 or x >= 1. The maximum amount she can purchase is x = 6 or x <= 6, thus 0 <= x <= 6. Plugging these two values into the function we get a range of 10 <= x <= 22.
The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?
Answer:
134 people
Step-by-step explanation:
80 / .6 = 133.333
Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people
A box of chocolates contains bars of milk chocolate and dark chocolate. The weight of each bar of milk chocolate and dark chocolate is 150 ounces and 100 ounces respectively. If the number of bars of dark chocolate is 12 more than the number of bars of milk chocolate, and the total weight of the chocolates in the box is 2950 ounces, find the number of bars of milk and dark chocolate.
Answer:
7 milk chocolate
19 dark chocolate
Step-by-step explanation:
It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.
Number of bars of milk chocolate: 17
Number of bars of dark chocolate: 29
Let's use algebraic equations to solve the problem. Let's denote the number of bars of milk chocolate as "x" and the number of bars of dark chocolate as "y."
1. Weight equation: The total weight of the chocolates in the box is 2950 ounces.
We can express this as an equation:
150x + 100y = 2950
2. Quantity equation: The number of bars of dark chocolate is 12 more than the number of bars of milk chocolate.
We can express this relationship as:
y = x + 12
Now, we have a system of two equations with two variables:
Equation 1 : 150x + 100y = 2950
Equation 2 : y = x + 12
To find the values of x and y, we can use substitution or elimination. Let's use substitution in this case.
From Equation 2, we can substitute the value of "y" in terms of "x" into Equation 1:
150x + 100(x + 12) = 2950
Now, we can solve for "x":
250x + 1200 = 2950
250x = 1750
x = 7
Now that we have the value of "x," we can find the value of "y" using Equation 2:
y = x + 12
y = 7 + 12
y = 19
So, the number of bars of milk chocolate (x) is 7, and the number of bars of dark chocolate (y) is 19.

A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
Answer:
0
Step-by-step explanation:
By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.
If line 1 is parallel to line 2, it means their slopes are the same.
So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].
A manufacturer has a monthly fixed cost of $40,000 and a product cost of $8 for each unit produced. The products sells for $12/unit.
Answer:
48,000
Step-by-step explanation:
The cost function by the given data is C(x) = 40,000 + 8x.
We are given that;
Monthly fixed cost = $40,000
The product cost for each unit produced= $8
Now,
The cost function is a function that gives the total cost of producing a certain number of units. The cost function depends on the fixed cost and the variable cost per unit. The fixed cost is the amount of money that the manufacturer has to pay regardless of how many units are produced, such as rent, salaries, utilities, etc. The variable cost per unit is the amount of money that the manufacturer has to pay for each unit produced, such as materials, labor, etc.
In this case, the fixed cost is $40,000 and the variable cost per unit is $8. To find the cost function, we need to add the fixed cost and the product of the variable cost per unit and the number of units.
We can use x to represent the number of units and C(x) to represent the cost function.
Then we have:
C(x) = fixed cost + (variable cost per unit)(number of units)
C(x) = 40,000 + (8)(x)
Therefore, by algebra the answer will be C(x) = 40,000 + 8x.

Find two consecutive even integers such that 4 times the smaller integer is 44 less than 7 times the larger integer
Answer:
let x be the smaller number.
let x + 2 be the larger number.
4 times the smaller number is 2 more than 3 times the larger number.
in equation form, this becomes:
4x = 3 * (x+2) + 2
simplify this to get:
4x = 3x + 6 + 2 which becomes:
4x = 3x + 8
subtract 3x from both sides of this equation to get:
x = 8
this means that x+2 = 10
the smaller number is 8 and the larger number is 10.
4 times the smaller number is equal to 32.
3 times the larger number + 2 is equal to 32.
requirements of the problem check out ok, so the solution is good.

Answer:
-155.15
-223.75
Step-by-step explanation:
Transaction 1 was a deposit of 360. The account had nothing in it before that deposit. After the 360 deposit the balance is 360.
Transaction 2 is -22.50. That means 22.50 was withdrawn (taken out) from the account. The balance after transaction 2 is 360 - 22.50 = 337.50.
Before transaction 3 takes place, the balance is 337.50.
After transaction 3 takes place, the balance is lower. It is now 182.35.
The amount of money taken out in transaction 3 is 337.50 - 182.35 = 155.15. Transaction 3 is -155.15.
The balance after transaction 3 is 182.35. The balance after transaction 4 is -41.40 which is lower than 182.35, so transaction 4 is again withdrawing money from the account.
The amount of transaction 4 is:
182.35 - (-41.40) = 223.75
Transaction 4 is: -223.75
Answer:
-155.15
