Answer:
so bro according to my calculations it's b good luck
just put it to slope or standard form
Answer:
23, 69 and 123
Step-by-step explanation:
let the first number be x then the second number is 3x ( 3 times the first) and the third number is x + 100 ( 100 more than the first number)
The sum of the three numbers is
x + 3x + x + 100 = 215
5x + 100 = 215 ( subtract 100 from both sides )
5x = 115 ( divide both sides by 5 )
x = 23
The 3 numbers are
x = 23, 3x = 3 × 23 = 69 and x + 100 = 23 + 100 = 123

Answer:
Step-by-step explanation:
Given vectors:
When subtracting vectors, we subtract the elements in the same position from one vector from the elements in the same position of the other vector. Therefore, subtracting vector b from vector c gives:
When multiplying a vector by a constant, we multiply each component of the vector by that constant. Therefore, multiplying vector a by 3 gives:
Multiply (c - b) by 1/4:
Finally, subtract the vectors:
Answer: The Van needs 18 gallons of gas to travel 360 miles.
Step-by-step explanation: Given that a Van travels 300 miles on 15 gallons of gas.
We are to find the number of gallons that the Van needs to travel 360 miles.
We will be using the UNITARY method to solve the given problem.
Number of gallons needed to travel 300 miles = 15.
So, number of gallons needed to travel 1 mile will be
Therefore, the number of gallons needed to travel 360 miles is given by
Thus, the Van needs 18 gallons of gas to travel 360 miles.
Amount of gas required to travel is .
Further explanation:
The word problems can be solved from the unitary method.
The unitary method is a method in which we have to first find the value of a single unit then further find the required value by multiplying the single unit value.
Given:
A van travelled on of gas.
Calculation:
Step 1:
First we have to find the number of gallons in one mile.
It is given that the number of gallons needed to travel is equal to .
Use the unitary method to calculate the number of gallons in one mile.
It is calculated as follows:
Step 2:
Now, we have to calculate the number of gallons needed to travel in .
Use the unitary method to calculate the required value by multiplying the single unit value.
The number of gallons in one mile is .
Therefore, the number of gallons in is calculated as follow:
Thus, the Van requires of gas to travel .
