Answer:
Amount of gas = 3.2 gallons
Required coordinate pair is (3.2, 12)
Step-by-step explanation:
Let x be the number of gallon of gas.
Given:
Berto has ⇒ y = $12
Gas cost per gallon ⇒ $3.75
Solution:
Using below formula.
Number of gallon of gas =
Now, we substitute total cost and gas cost per gallon.
Therefore, Berto can buy 3.2 gallon of gas and required coordinate pair is (3.2, 12).
To add 1/2 and 1/4 you need a common denominator. The common denominator is 4. Multiply 1/2 × 2/2 and you get 2/4
Now you have 6 2/4 + 2 1/4
6+2=8 and 2/4+1/4=3/4
Your answer is 8 3/4 or 8.75
Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school
Answer:
The total number of cups of coffee is 12x - 3 ⇒ last answer
Step-by-step explanation:
- Madden and Jenn both worked at the coffee shop today
- Madden's total cups of coffee made is represented by f(x) = 7x - 4
- Jenn's total cups of coffee made is represented by g(x) = 5x + 1
- We want to write a function represents the total cups of coffee they
made together
∵ f(x) represents the number of cups of coffee that Madden made
∵ f(x) = 7x - 4
∵ g(x) represents the number of cups of coffee that Jenn made
∵ g(x) = 5x + 1
- To find the total cups they made together we will add the two
functions f(x) and g(x)
∵ f(x) + g(x) = (7x - 4) + (5x + 1)
- Add like terms
∴ f(x) + g(x) = (7x + 5x) + (-4 + 1)
∴ f(x) + g(x) = 12x + (-3)
-Remember (+)(-) = (-)
∴ f(x) + g(x) = 12x - 3
* <em>The total number of cups of coffee is 12x - 3</em>
