In order to solve this equation you could use guess and check with multiple choice, or you can set up a system of equations.
First we must define our variables:
x=price of taco
y=price of burrito
Michael bought 4 tacos (4x) and (+) and Burrito (y) for $9.50 (=9.5)
4x+y=9.50
Noah bought two tacos (2x) and (+) three burritos (3y) for (=) $11 (11)
2x+3y=11
To solve this system of equations you can easily see substitution as the easiest method. For substitution we must isolate one variable:
4x+y=9.50
y=-4x+9.5
We can now replace the y in the other equation:
2x+3(-4x+9.5)=11
Then solve this equation to get the price of a taco (x)
2x-12x+28.5=11
-10x=-17.5
x=1.75
The price of a taco would be $1.75
Answer: 10
Step by Step Solution:
You have x and y as your axis’s and that as your table with x being time and y being percent bounded. As for that you got (0, 0) and (5, 50).
Then you plug those numbers into the equation to finding slope: m = y2 - y1 / x2 - x1 to have m = 50 - 0 / 5 - 0
Then you have to simply the equation to have m = 50 / 5 and then you divide them as the line of a fractions means division and you will have m = 10
Answer:
V = 314
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 5
h = 12
Work:
V = πr²(h/3)
V = 3.14(5²)(12/3)
V = 3.14(25)(4)
V = 314
Answer:
63.6m²
Step-by-step explanation:
The radius is 4.5m because it's half of the diameter.
Area = πr²
Area = π(4.5)² = 63.6m²
