Answer: Option D
D. 880 = 45d + 70; 18 days
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call d the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
The answer is the option D

Multiply each variable quantity by 2 and combine.
The midpoint formula is basically (averaging the x coordinates, averaging the y coordinates).
Point A: (3, 7)
Point B: (2, -1)
Midpoint x: (3 + 2) / 2 = 5 / 2
Mindpoint y: (7 - 1) / 2 = 3
Therefore, the midpoint of the segment is choice C (5/2, 3)
Answer:
B
Step-by-step explanation:
Three ways you can use an electric current:
1. in a battery to power a flashlight or other devices
2. to produce heat
3. using a power tool
4. chargers
If the two requirements of an electric<span> circuit are met, then charge will flow through the external circuit. Causing a </span> flow of electric charge to power any machine or device, etc.
