Answer:
4
Step-by-step explanation:
If ten people each get three slices, they will need 30 pieces.
10 x 3 = 30
Each pizza has 8 slices, so we divide 30 by 8 to get the number of pizzas needed.
30 / 8 = 3.75
You can't buy 3.75 pizzas, so you must get 4 to ensure everyone gets enough.
Answer:
x=4
Step-by-step explanation:
13x+1 = 11x+9
13x-11x = 9-1
2x = 8
x = 4
Answer:
Step-by-step explanation:
To find the inverse of a function f (x) follow the steps below:
1) Make y = f (x)
2) Solve for the variable x
3) Exchange the variable x with the variable y
4) Make
Finally, the inverse of the function f (x) is:
Answer:
The inverse is g(x) = 3x + 6
Step-by-step explanation:
f(x) = x/3 - 2
y = x/3 - 2
To find the inverse, swap x and y, then put it in y = mx + b
x = y/3 - 2
y/3 = x + 2
y = 3x + 6
g(x) = 3x + 6
Answer:
The area of the triangular garden is
Step-by-step explanation:
we know that
The equilateral triangle has three equal sides and three equal internal angles (the measure of each internal angle is 60 degrees)
The area of a triangle applying the law of sines is equal to
In this problem we have a equilateral triangle
therefore
substitute
