First one; substitute x into the equation and see if the result equal y in the coordinate
Answer:let x be the number of cars, and 7-x be the number of trucks.
25x + 30(7-x) = 195
25x + 210-30x = 195
5x = 15
x = 3
So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks
4 Trucks were not rented.
Step-by-step explanation:
Answer:
Amount of milk in each milkshake = 7 2/3 gallons
Step-by-step explanation:
Gallons of milk = 23 (given)
Number of Milkshakes = 3
Because the gallons of milk were shared equally,
Amount of milk in each milkshake = 23/3 = 7 2/3 gallons of milk
y = -13, 13
There are two answers because you are taking the square root of a number. If we go the other way, to check our work, (-13)^2 = 169 and (13)^2 = 169.
Hope this helps! :)
