Answer:
n = 13
Step-by-step explanation:
374 = 11(2n+8)
Expand the right side
374 = 11* 2n + 11 * 8
374 = 22n + 88
Subtract 88 from both sides
374 - 88 = 22n
286 = 22n
divide both sides by 22
n = 13
Answer:
Raquel should adjust the number of rotations to 115.81 rotations
Step-by-step explanation:
step 1
Find the circumference of the wheels that are 2.5 cm in diameter
The circumference is equal to
we have
assume
substitute
step 2
Find the number of rotations
Divide 10 meters by the circumference
step 3
For a diameter of 2.75 cm find how should she adjust the number of rotations so that the robot travels the same distance
Find the circumference of the wheels
The circumference is equal to
we have
assume
substitute
step 4
Find the number of rotations
Divide 10 meters by the circumference
G(-1) = -1
g(1) = - (1 + 1)² + 1 = 5
g(3) = - 1/2 (3) + 2 = 3 1/2
Answer: -1, 5 , 3 1/2
I think it’s gonna be 3 and 5 to make 8
2x + 6 = 5x - 14
5x - 2x = 6 + 14
3x = 20
x = 20/3
