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:
-8x+4=36
-4 -4
-8x=32
divde be -8 on both sides
x=-4
A=35+5t, b=100-8t, a=b when:
35+5t=100-8t subtract 35 from both sides
5t=65-8t add 8t to both sides
13t=65 divide both sides by 13
t=5 minutes
a=35+5(5)=60 gallons
So the tanks have an equal volume of 60 gallons after five minutes.
Because the base (2) is positive and greater than 1, the function / graph is increasing. To find the y-intercept, let x= 0 and find y: y = 3(2)^0 = 6, so the y-intercept is (0,6). There is no x-ntercept because the graph and the function are always positive / above the x-axis.
Answer:
If they're equal set them equal to each other if they're supplementary you set up an equation. Where you add them up and set them equal to 180. And then you just want to solve for X.
